FOREWORD
This Military Standard sets forth practices for the preparation,
interpretation, change, and revision of program-peculiar specifications prepared
by or for the Departments and Agencies of the Department of Defense.
This Military Standard was prepared to establish uniform specification
practices in response to the need for a document comparable to DOD-STD-100
covering engineering drawing practices and in recognition of the configuration
identification concepts of the DOD Configuration Management Program established
by DOD Directive 5010.19 and DOD Instruction 5010.21.
This Military Standard is arranged in six sections and 15 appendixes. Section
1 states the scope of the standard. Section 2 lists the referenced documents.
Section 3 states broad requirements, concepts, and practices applicable to
specifications in general. Section 4 states general requirements for each of the
six sections of a specification. The second digit of the paragraph numbering of
Section 4 corresponds with the numbering of the six specification sections.
Section 5 invokes the detailed requirements of the appendixes which are outlines
for various types of specifications. Section 6 contains a list of Data Item
Descriptions (DIDs) applicable to this standard.
This Standard, although primarily intended for use in preparation of
program-peculiar specifications, recognizes the probability that some items,
processes, or materials covered by specifications prepared to this Standard will
be subject to conversion by Government agencies to Federal or Military
specifications for use as a Mandatory Specification as required by FAR
1-1202(a). Therefore, specifications prepared in accordance with this Standard,
when subject to all pertinent conversion requirements of DOD 4120.3-M and
assigned Federal or Military specification numbers, will be in full compliance
with requirements for Federal and Military specifications.
Although this standard is specifically applicable to MIL-S-83490 Form 1a
specifications only, its use as a guidance document for the preparation of other
forms is encouraged.

C3 Non-Complex Item Fabrication
C4 Inventory Item
C5 Software
Type D - Process Specification
Type E - Material Specification
1.4.1 Program-peculiar. Configuration items, processes and materials as
used in this standard, include all configuration items, processes and
materials conceived, developed, reduced to practice or first documented for
the development, procurement, production, assembly, installation, testing or
support of the system/equipment/software/end product (including their
components and supporting configuration items) developed or initially procured
under a specific program. For all Army applications of this standard, this
paragraph shall read as follows:
1.4.1 PROGRAM-PECULIAR items, processes and materials as used in this
standard, include only those items, processes and materials conceived,
developed, reduced to practice or first documented for the development,
procurement, production, assembly, installation, testing and support of the
system/ equipment/end item (including their components and supporting items)
developed or initially procured under a specific program for which there would
be judged to be no potential for use by subsequently developed systems. In
other words, program-peculiar items, processes and materials will be only
those which are obviously only one-of-a-kind and, therefore, little or no
potential exists for elimination through Item Reduction Studies or for any
future use."

3. REQUIREMENTS
3.1 Introduction. Specifications prepared in accordance with this standard
are intended for use in design and procurement of configuration items and for
services required for program-peculiar application.
3.1.1 Configuration identification. Current configuration identification is
established by baseline configuration identification documents and all
effected changes. Configuration identification documents include all those
necessary to provide a full technical description of the characteristics of
the configuration item that require control at the time that the baseline is
established (see 6.2).
3.1.1.1 Functional Configuration Identification (FCI).
Functional configuration identification (functional baseline and approved
changes) will normally include a Type A specification or a Type B
specification supplemented by other specification types as necessary to
specify: (1) all essential system functional characteristics; (2) necessary
interface characteristics; (3) specific designation of the functional
characteristics of key configuration items; and (4) all of the tests required
to demonstrate achievement of each specified characteristic (see 6.2).
3.1.1.2 Allocated Configuration Identification (ACI).
Allocated configuration identification (allocated baseline and approved
changes) normally consists of a series of Type B specifications defining the
requirements including functional, for each major configuration item. These
may be supplemented by other types of specifications, engineering drawings and
related data, as necessary, to specify: (1) all of the essential configuration
item characteristics including delineation of interfaces;(2) physical
characteristics necessary to assure compatibility with associated systems,
configuration items and inventory items; and (3) all of the tests required to
demonstrate achievement of each specified functional characteristic (see
6.2).
3.1.1.3 Product Configuration Identification (PCI). The product
configuration identification (product baseline and approved changes) will
normally include specification Types C, D, and E, engineering drawings and
related data, as necessary, to provide a set of documents adequate for the
procurement, production, test, evaluation, and acceptance of a configuration
item without requiring further development work. This set of documents
provides that technical description which describes the required physical
characteristics of a configuration item; the functional characteristics
designated for production acceptance testing; and required acceptance
tests.
3.1.2 Coverage of specifications. Specifications may be prepared to cover a
group of products, services or materials, or a single product, service or
material, and are general or detail specifications, respectively, and either may
be prepared as any of the types specified herein.
3.1.2.1 General specification. A general specification covers requirements
common to two or more types, classes, grades, or styles of products, services,
or materials; this avoids repetition of common requirements in detail
specifications. It also permits changes to common requirements to be readily
effected. General specifications may also be used to cover common requirements
for weapon systems and subsystems.
3.1.2.2 Detail specification. A detail specification covers all
requirements for one or more types of configuration items or services so as
not to require preparation and reference to a general specification for the
common requirements. A detail specification may also take the form of a
specification sheet, which is incomplete without reference to a general
specification. The detail and referenced general specification (which contains
the requirements common to the family configuration items) then constitute the
total requirements. In either instance, detail specifications shall be
prepared in six-section format described in Section 3 and 4 of this
standard.
3.1.3 Types. General Requirements for specification types are as follows:
3.1.3.1 Type A - System/segment specification. This type of specification
states the technical and mission requirements for a system/segment as an
entity, allocates requirements to functional areas, documents design
constraints, and defines the interfaces between or among the functional areas.
Normally, the initial version of a system/segment specification is based on
parameters developed during the Concept Exploration phase. This specification
(initial version) is used to establish the general nature of the system that
is to be further defined and finalized during the Demonstration and Validation
phase. The system/segment specification is maintained current during the
Demonstration and Validation phase, culminating in a revision that forms the
future performance base for the development and production of the prime items
and configuration items. The System/Segment Specification shall be prepared by
the contractor and shall be in accordance with the format and content of the
System/ Segment Specification Data Item Description (see 6.2).
3.1.3.2 Type B - Development specifications. Development specifications
state the requirements for the design or engineering development of a product
during the development period. Each development specification shall be in
sufficient detail to describe effectively the performance characteristics that
each configuration item is to achieve when a developed configuration item is
to evolve into a detail design for production. The development specification
should be maintained current during production when it is desired to retain a
complete statement of performance requirements. Since the breakdown of a
system into its elements involves configuration items of various degrees of
complexity which are subject to different engineering disciplines or
specification content, it is desirable to classify development specifications
by sub-types. The characteristics and some general statements regarding each
sub-type are given in the following paragraphs (see
6.2).
3.1.3.2.1 Type B1 - Prime item development specification.
(See Appendix II for outline of form). A prime item development
specification is applicable to a complex item such as an aircraft, missile,
launcher equipment, fire control equipment, radar set, training equipment,
etc. A prime item development specification may be used as the functional
baseline for a single configuration item development program or as part of the
allocated baseline where the configuration item covered is part of a larger
system development program. Normally configuration items requiring a Type B1
specification meet the following criteria:
a. The prime item will be received or formally accepted by the contracting
agency on a DD Form 250, sometimes subject to limitations prescribed
thereon.
b. Provisioning action will be required.
c. Technical manuals or other instructional material covering operation and
maintenance of the prime item will be required.
d. Quality conformance inspection of each prime item, as opposed to
sampling, will be required.
3.1.3.2.2. Type B2 - Critical item development specification.
(See Appendix III for outline of form.) A Type B2 specification is
applicable to a configuration item which is below the level of complexity of a
prime item but which is engineering critical or logistics critical.
a. A critical item is engineering critical where one or more of the
following applies:
(1) The technical complexity warrants an individual specification.
(2) Reliability of the critical item significantly affects the ability of
the system or prime item to perform its overall function, or safety is a
consideration.
(3) The prime item cannot be adequately evaluated without separate
evaluation and application suitability testing of the critical item.
b. A critical item is logistics critical where the following apply:
(1) Repair parts will be provisioned for the item.
(2) The contracting agency has designated the item for multiple source
reprocurement.
3.1.3.2.3 Type B3 - Non-Complex item development specification. (See
Appendix IV for outline of form.) This type of specification is applicable to
configuration items of relatively simple design which meet all of the
following criteria:
a. During development of the system or configuration item, the non-complex
item can be shown to be suitable for its intended application by inspection or
demonstration.
b. Acceptance testing to verify performance is not required.
c. Acceptance can be based on verification that the item, as fabricated,
conforms to the drawings.
d. The end product is not software.
Examples of configuration items which normally meet the above criteria are:
special tools, work stands, fixtures, dollies, and brackets. Many such simple
configuration items can be defined adequately during the development phase by a
sketch and during production by a drawing or set of drawings. If drawings will
suffice to cover all requirements, and unless a specification is required by the
Government contracting agency, a specification for a particular non-complex item
need not be prepared. However, when it is necessary to specify several
performance requirements in a formal manner to ensure development of a
satisfactory configuration item or when it is desirable to specify detailed
verification procedures, the use of a specification of this type is
appropriate.
3.1.3.2.4 Type B4 - Facility or ship development specification. (See
Appendix V for outline of form.) A facility or ship development specification
is applicable to each HWCI which is both a fixed (or floating) installation
and an integral part of a system. Examples of facility/ship requirements are:
basic structural, architectural or operational features designed specifically
to accommodate the requirements unique to the system and which must be
developed in close coordination with the system; the facility or ship services
which form complex interfaces with the system; facility or ship hardening to
decrease the total system’s vulnerability; and ship speed, maneuverability,
etc. A development specification for a facility or ship establishes the
requirements and basic restraints/constraints imposed on the development of an
architectural and engineering design for such facility or ship. The product
specifications for the facility or ship are prepared by the
architectural/engineering activity, and their type and format are not
prescribed by this standard.
3.1.3.2.5 Type B5 - Software development specification (see 6.2). Software
development specifications are applicable to the development of computer
software and consist of a Software Requirements Specification and Interface
Requirements Specification(s).
3.1.3.2.5.1 Software Requirements Specification. This type of specification
describes in detail the functional, interface, quality factor, special, and
qualification requirements necessary to design, develop, test, evaluate and
deliver the required Computer Software Configuration Item (CSCI). The Software
Requirements Specification shall be prepared by the contractor and shall be in
accordance with the format and content of the Software Requirements
Specification Data Item Description (See 6.1).
3.1.3.2.5.2 Interface Requirements Specification. This type of
specification describes in detail the requirements for one or more CSCI
interfaces in the system, segment, or prime item. The specified requirements
are those necessary to design, develop, test, evaluate, and deliver the
required CSCI. The interface requirements may be included in the associated
Software Requirements Specifications under the following conditions: (1) there
are few interfaces, (2) few development groups are involved in implementing
the interface requirements, (3) the interfaces are simple, or (4) there is one
contractor developing the software. The Interface Requirements Specification
shall be prepared by the contractor(s) and shall be in accordance with the
format and content of the Interface Requirements Specification Data Item
Description (see 6.2).
3.1.3.3 Type C - Product Specifications. Product specifications are
applicable to any configuration item below the system level, and may be
oriented toward procurement of a product through specification of primarily
functional (performance) requirements or primarily fabrication (detailed
design) requirements. Sub-types of product specifications to cover equipments
of various complexities or requiring different outlines of form are covered in
paragraphs 3.1.3.3.1 through 3.1.3.3.5.
a. A product function specification states (1) the complete performance
requirements of the product for the intended use, and (2) necessary interface
and interchangeability characteristics. It covers form, fit, and function.
Complete performance requirements include all essential functional
requirements under service environmental conditions or under conditions
simulating the service environment. Quality assurance provisions for hardware
include one or more of the following inspections: qualification evaluation,
preproduction, periodic production, and quality conformance.
b. A product fabrication specification will normally be prepared when both
development and production of the HWCI are procured. In those cases where a
development specification (Type B) has been prepared, specific
reference to the document containing the performance
requirements for the HWCI shall be made in the product fabrication
specification. These specifications shall state: (1) a detailed description of
the parts and assemblies of the product, usually by prescribing compliance
with a set of drawings, and (2) those performance requirements and
corresponding tests and inspections necessary to assure proper fabrication,
adjustment, and assembly techniques. Tests normally are limited to acceptance
tests in the shop environment. Selected performance requirements in the normal
shop or test area environment and verifying tests therefore may be included.
Preproduction or periodic tests to be performed on a sampling basis and
requiring service, or other, environment may reference the associated
development specification. Product fabrication specifications may be prepared
as Part II of a two-part specification (See 3.1.4) when the contracting agency
desires close relationships between the performance and fabrication
requirements.
3.1.3.3.1 Type C1 -Prime item product specifications. Prime item product
specifications are applicable to configuration items meeting the criteria for
prime item development specifications (Type B1) as stated in paragraph
3.1.3.2.1. They may be prepared as function or fabrication specifications as
determined by the procurement conditions.
3.1.3.3.1.1 Type C1a - Prime item product function specification. (See
Appendix VII for outline of form.) A type C1a specification is applicable to
the procurement of prime items when a "form, fit and function" description is
acceptable. Normally, this type of specification would be prepared only when a
single procurement is anticipated and training and logistic considerations are
unimportant.
3.1.3.3.1.2 Type C1b - Prime item product fabrication specification. (See
Appendix VIII for outline of form.) Type C1b specifications are normally
prepared for procurement of prime items when: a detailed design disclosure
package needs to be made available; it is desired to control the
interchangeability of lower level components and parts; and service
maintenance and training are significant factors.
3.1.3.3.2 Type C2 - Critical item product specifications.
Type C2 specifications are applicable to engineering or logistic critical
items as specified in paragraph 3.1.3.2.2, and may be prepared as function or
fabrication specifications.
3.1.3.3.2.1 Type C2a - Critical item product function specification. (See
Appendix IX for outline of form.) A type C2a specification is applicable to a
critical item where the critical item performance characteristics are of
greater concern than part interchangeability or control over the details of
design, and a "form, fit and function" description is adequate.
3.1.3.3.2.2. Type C2b - Critical item product fabrication specification.
(See Appendix X for outline of form.) A C2b specification is applicable to a
critical item when a detailed design disclosure needs to be made available or
where it is considered that adequate performance can be achieved by adherence
to a set of detail drawings and required processes.
3.1.3.3.3 Type C3 - Non-complex item product fabrication specification.
(See Appendix XI for outline of form.) A non-complex item product fabrication
specification is applicable to non-complex items as specified in paragraph
3.1.3.2.3. Where acquisition of a non-complex item to a detailed design is
desired, a set of detail drawings may be prepared in lieu of a
specification.
3.1.3.3.4 Type C4 - Inventory item specification. (See Appendix XII for
outline of form.) This type of specification identifies applicable inventory
items (including their pertinent characteristics) that exist in the DOD
inventory and which will be incorporated in a prime item or in a system being
developed. The purpose of the inventory specification is to stabilize the
configuration of inventory items in the DOD inventory on the basis of both
current capabilities of each inventory item and the requirements of the
specific application, or to achieve equipment/component item standardization
between or within a system or prime item. This puts the Government on notice
as to the performance and interface characteristics that are required, so that
when ECP’s for an inventory item are evaluated the needs of the various
applications may be kept in mind. If this is not done, design changes may make
an inventory item unsuitable for the system. A separate inventory item
specification should be prepared, as required, for each system, subsystem,
prime item or critical item in which inventory items are to be installed or
which require the support of inventory items.
3.1.3.3.5 Type C5 - Software Product Specification (see 6.2).
The Software Product Specification is applicable to the delivered CSCI and
is sometimes referred to as the "as built" software specification. This
specification consists of the final updated version of the Software Top-Level
Design Document, the Software Detailed Design Document, the Data Base Design
Document(s), the Interface Design Document(s), and the source and object
listings of the software. The Software Product Specification shall be prepared
by the contractor and shall be in accordance with the format and content of
the Software Product Specification Data Item Description (see 6.2).
3.1.3.3.5.1 Software Top Level Design Document. The Software Top Level
Design Document describes how the top-level computer software components
(TLCSCs) implement requirements allocated from the Software Requirements
Specification and, if applicable, Interface Requirements Specification(s). The
Software Top Level Design Document shall be prepared by the contractor and
shall be in accordance with the format and content of the Software Top Level
Design Document Data Item Description (see 6.2).
3.1.3.3.5.2 Software Detailed Design Document. The Software Detailed Design
Document describes the detailed decomposition of TLCSCs to lower level
computer software components (LLCSCs) and units. The Software Detailed Design
Document shall be prepared by the contractor and shall be in accordance with
the format and content of the Software Detailed Design Document Data Item
Description (see 6.2).
3.1.3.3.5.3 Data Base Design Document. The Data Base Design Document
describes one or more data base(s) used by the CSCI. If there is more than one
data base, each data base may be described in a separate Data Base Design
Document. The Data Base Design Document(s) shall be prepared by the contractor
and shall be in accordance with the format and content of the Data Base Design
Document Data Item Description (see 6.2).
3.1.3.3.5.4 Interface Design Document. The Interface Design Document
provides the detailed design of one or more CSCI interfaces. When Interface
Requirements Specifications have been prepared, associated Interface Design
Documents shall be prepared as well. The Interface Design Document shall be
prepared by the contractor and shall be in accordance with the format and
content of the Interface Design Document Data Item Description (see 6.2).
3.1.3.4 Type D - Process specifications. (See Appendix XIV for outline of
form.) This type of specification is applicable to a service which is performed
on a product or material. Examples of processes are: heat treatment, welding,
plating, packing, microfilming, marking etc. Process specifications cover
manufacturing techniques which require a specific procedure in order that a
satisfactory result may be achieved. Where specific processes are essential to
fabrication or procurement of a product or material, a process specification is
the means of defining such specific processes. Normally, a process specification
applies to production but may be prepared to control the development of a
process.
3.1.3.5 Type E - Material specifications. (See Appendix XV for outline of
form.) This type of specification is applicable to a raw material (chemical
compound), mixtures (cleaning agents, paints), or semi-fabricated material
(electrical cable, copper tubing) which are used in the fabrication of a
product. Normally, a material specification applies to production but may be
prepared to control the development of a material.
3.1.4 Two-part specifications. Two-part specifications, which combine both
development (performance) and product fabrication (detail design)
specifications under a single specification number as Part I and Part II
respectively, may be selected as a contracting agency option. This practice
requires both parts for a complete definition of both performance requirements
and detailed design requirements governing fabrication. Under this practice,
the development specification remains alive during the life of the HWCI as the
complete statement of performance requirements. Proposed design changes must
be evaluated against both the product fabrication and the development parts of
the specification. To emphasize the fact that two parts exist, both parts
shall be identified by the same specification number and each part shall be
further identified as Part I or Part II, as appropriate. Two-part
specifications are not applicable when the product specification is a product
function specification or when it is a computer software specification.
3.2 Style, format and identification of specifications.
3.2.1 General. This section covers style, format, and general instructions
for preparing a specification. This includes material arrangement,
paragraphing, numbering, heading, and concluding material.
3.2.2 Sectional arrangement of specifications. Specifications shall contain
six numbered sections, and appendixes as required, titled and numbered as
shown below.
1. SCOPE
2. APPLICABLE DOCUMENTS
3. REQUIREMENTS
4. QUALIFICATION REQUIREMENTS (for software) or QUALITY ASSURANCE PROVISIONS
(for hardware)
4. PREPARATION FOR DELIVERY
6. NOTES
10. APPENDIX
Subject matter shall be kept within the scope of the sections so that the
same kind of requirements or information will always appear in the same section
of every specification. Except for appendixes, if there is no information
pertinent to a section, the following shall appear below the section
heading:
"This section is not applicable to this
specification."
3.2.3 Language style. The paramount consideration in a specification is its
technical essence, and this should be presented in language free of vague and
ambiguous terms and using the simplest words and phrases that will convey the
intended meaning. Inclusion of essential information shall be complete,
whether by direct statements or references to other documents (See 3.1.4).
Consistency in terminology and organization of material will contribute to the
specification’s clarity and usefulness. Sentences shall be as short and
concise as possible. Punctuation should aid in reading and prevent misreading.
Well-planned word order requires a minimum of punctuation. When extensive
punctuation is necessary for clarity, the sentence(s) shall be rewritten.
Sentences with compound clauses shall be converted into short and concise
sentences.
3.2.3.1 Capitalization, spelling, etc. Except where DOD requirements
differ, the United States Government Printing Office Style Manual shall be
used as a guide for capitalization, spelling, punctuation, syllabification,
etc. Merriam-Webster’s New International dictionary (latest revision) will be
consulted when the Style Manual does not provide the guidance needed.
3.2.3.2 Abbreviations. The applicable standard abbreviations listed in
MIL-STD-12 shall be used, except that abbreviations in titles of
specifications shall be in accordance with Cataloging Handbook H6-1. The only
other abbreviations employed shall be those in common usage and not subject to
misinterpretation. The first time an abbreviation is used in text, it shall be
placed in parentheses following the word or term spelled out in full; e.g.,
pounds per square inch (psi). This rule does not apply to abbreviations used
for the first time in tables and equations; uncommon abbreviations so used
shall be explained in the text or footnotes.
3.2.3.3 Symbols. Symbols shall not be used in text, but may be used in
equations and tables. Graphic symbols, when used in figures shall be in
accordance with military standards. (Any symbol formed by a single character
should be avoided if practicable, since an error destroys the intended
meaning.)
3.2.3.4 Proprietary names. Trade names, copyrighted names, or other
proprietary names applying exclusively to the product of one company shall not
be used unless the configuration item(s) require source control or cannot be
adequately described because of the technicality involved, construction, or
composition. In such instances, one, and if all pertinent requirements are
specified, several, commercial products may be included by inserting the words
"or equal" after the trade name to assure wider competition and that bidding
will not be limited to a particular make specified. The same applies to
manufacturer’s part numbers or drawing numbers for minor parts when it is
impractical to specify all detail requirements in the specification. In all
instances where "or equal" is permitted, the particular characteristics
required shall be included to define "or equal".
3.2.3.5 Commonly used words and phrasing. Certain words and phrases are
frequently used in a specification. The following rules shall be followed:
a. Referenced documents shall be cited thus "conforming to ..." "as
specified in ..." or "in accordance with ...".
b. "Unless otherwise specified" shall be used to indicate an alternative
course of action. The phrase shall always come at the beginning of the
sentence, and if possible, at the beginning of the paragraph. This phrase
shall be used only when it is possible to clarify its meaning by providing a
reference such as to Section 6 of the specification for further clarification
in the contract or order or otherwise.
c. When making reference to a requirement in the specification and the
requirement referenced is rather obvious or not difficult to locate, the
simple phrase "as specified herein" is sufficient and should be used.
d. The phrase "... to determine compliance with ..." or "... to determine
conformance to ..." should be used in place of "... to determine compliance to
...". In any case use the same wording throughout.
e. In stating positive limitations, the phrase shall be stated thus: "The
diameter shall be no greater than
...".
f. The emphatic form of verb shall be used throughout the specification;
i.e., state in the requirements section that "The indicator shall be
designated to indicate ...", and in the section containing test provisions
"The indicator shall be turned to zero and 230 volts alternating current
applied." For specific test procedures, the imperative form may be used
provided the entire method is preceded by "the following tests shall be
performed," or related wording. Thus, "Turn the indicator to zero and apply
230 volts alternating current."
g. Capitalize the words "drawing," "bulletin," etc., only when they are
used immediately preceding the number of a document. However, Federal and
military standards, and handbooks shall be identified in the text only by
their symbol and number; thus "MIL-E-000," not, "specification MIL-E-OOO."
3.2.3.6 Use of "shall," will," "should," and "may". Use "shall" whenever a
specification expresses a provision that is binding. Use "should" and "may"
wherever it is necessary to express non-mandatory provisions. "Will" may be used
to express a declaration of purpose on the part of the contracting agency. It
may be necessary to use "will" in cases where the simple future tense is
required, i.e., power for the motor will be supplied by the ship.
3.2.3.7 Use of "flammable" and "nonflammable". The terms "flammable" and
"nonflammable" shall be used in specifications in lieu of the terms
"inflammable", "uninflammable", and
"noninflammable".
3.2.4 Paragraph numbering. Each paragraph and subparagraph shall be numbered
consecutively within each section of the specification, using a period to
separate the number representing each breakdown. Example for Section 3 of
specification:
3. REQUIREMENTS
3.2 Second Paragraph
Or:
3. REQUIREMENTS
Itemization with a paragraph or subparagraph shall be identified by lowercase
letters to avoid confusion with paragraph numerals. For clarity of text,
paragraph numbering shall be limited to seven levels.
3.2.5 Paragraph identification. If practicable, each paragraph and
subparagraph shall be given a subject identification. the first letter of the
first word in the paragraph identification shall be capitalized. Paragraph
identifications in any one section shall not be duplicated. Primary paragraphs
identifications shall be in boldfaced type and subparagraph identifications
italicized when typeset. When typewritten, paragraph identification shall be
underlined.
3.2.6 Underlining. Do not underline any portion of a paragraph or
capitalize phrases or words for the sake of emphasis with the exceptions noted
in 3.2.5. All of the requirements are important in obtaining the desired
product or service.
3.2.7 Cross references. Cross references, that is references to parts
within the specification, shall be held to a minimum. Cross references shall
be used only to clarify the relationship of requirements within the
specification and to avoid inconsistencies and unnecessary repetition. When
the cross reference is to a paragraph, subparagraph, etc., within the
specification, the cross reference shall be only to the specific paragraph
number. The word paragraph shall not appear.
3.2.8 Figures. A figure is a picture or graph, and constitutes an integral
part of the specification. It shall be clearly related to, and consistent
with, the text of the associated paragraph. Figures should not be confused
with numbered and dated drawings referenced in the text which shall be listed
in Section 2 and not physically incorporated in the specification.
3.2.8.1 Location of figures in specification. Each figure shall be placed
following, or within, the paragraph containing a reference to it. If figures
are numerous and their location, as indicated above, would interfere with
correct sequencing of paragraphs and cause difficulty in understanding or
interpretation, they may be placed in numerical sequence at the end of the
specification before any appendix or index.
3.2.8.2 Preparation of figures. All figures shall be titled, and they shall
be numbered consecutively with Arabic numerals in the order in which they are
initially referenced in the specification.
3.2.9 Tables. A table is an arrangement of data in lines and columns. It
shall be used when data can thus be presented more clearly than text. Elaborate
or complicated tables shall be avoided. References in the text shall be
sufficiently detailed to make the purpose of the table clear, and the table
shall be restricted to data pertinent to the associated
text.
3.2.9.1 Location of tables in specifications. A table shall be placed
following, or within, the paragraph containing a
reference to it. If space does not permit, a table shall
be
placed at the beginning of the succeeding page, or if extensive, on a
separate page. If tables are numerous and their location, as indicated above,
would interfere with correct sequencing of paragraphs and cause difficulty in
understanding or interpretation, they may be placed in numerical sequence at
the end of the specification before any appendix or index.
3.2.9.2 Preparation of tables. The tables shall be numbered consecutively
with Roman numerals in the order in which they are initially referenced in the
specification. The number and title shall be placed above the table. The
contents of a table shall be organized and arranged to show clearly the
significance and relationship of the data. Data included in the text shall not
be repeated in the table. Tables shall be boxed in and ruled. When a table is
of such width as to make it impracticable to place it in normal position on
the page, it shall be rotated counterclockwise 90 degrees.
3.2.10 Foldouts. Foldouts shall be avoided except where required for
legibility. Large tables or figures may be broken out so that they may be
printed on facing pages. Where foldouts are required, they should be grouped in
one place, preferably at the end of the specification (in the same location as
figures) and suitable reference to their location shall be included in the
text.
3.2.11 Footnotes.
3.2.11.1 Footnotes to text. Footnotes to the text shall be avoided if
possible. Their purpose is to convey additional information that is not
properly a part of the text. A footnote to the text shall be placed at the
bottom of the page containing the reference to it.
3.2.11.2 Footnotes to tables and figures. Footnotes to a table or figure
shall be placed below the table or figure. The footnotes may contain mandatory
information that cannot be presented as data within a table. Footnotes shall
be numbered separately for each table. Where numerals will lead to ambiguity
(for example in connection with a chemical formula), superior letters,
asterisks, daggers, and other symbols may be used.
3.2.12 Contractual and administrative requirements. A specification shall not
include contractual requirements which are properly a part of the contract; such
as cost, time of delivery, instructions on reworking or resubmitting rejected
items or lots method of payment, liquidated damages, provision for configuration
items damaged or destroyed in tests, etc. Contractual, administrative, and
warranty provisions such as those covered in general provisions of contracts,
shall not be made part of the requirements in the specification. Contractual and
administrative provisions not covered in the general provisions, but considered
essential for procurement, may be indicated as "ordering data" or "features to
be included in bids or in contract" in Section 6. This provision shall be
exercised with caution and limited to essential matters.
3.2.13 Definitions in specifications. The inclusion of a definition can be
avoided if requirements are properly stated. When the meaning of one or more
terms must be established in the specification, definitions shall be placed in
the text. However, it is often clearer to list one or more definitions in
Section 6, especially where the terms are used in many places throughout the
specification. When this is done, a parenthetical reference to the applicable
paragraph in Section 6 shall follow the terms to indicate the existence of a
definition.
3.2.14 References to other documents. Referencing is the approved method for
including requirements in specifications where this eliminates the repetition of
requirements and tests that are adequately set forth elsewhere. However, chain
referencing should be avoided. References shall be restricted to documents that
are specifically and clearly applicable to the specification, and are current
and available. Care shall be taken in writing the specification to indicate in a
positive manner the extent to which a referenced document is applicable. The
specification shall also include any special details called for by the
referenced document.
Reference to paragraph numbers in other documents shall not be
made. The reference shall be to a title, method number, specifically
identified requirement, or other definitive designation.
3.2.14.1 Limitation on references. A specification shall not contain
anything in conflict with provisions in referenced documents unless it is
desirable to make special exceptions to such provisions, in which case the
specific provision to which exception is made shall be stipulated or the
application of a specific portion of the referenced document shall be clearly
defined. It is not intended that other documents be made a part of a
specification by reference unless the items, materials, tests, or other
services in the referenced documents are required in the quality and detail
which these documents are designed to produce. The applicability of all
referenced documents listed in Section 2 of a specification shall be defined
in Section 3, 4, or 5, as appropriate. The extent of applicability of
referenced documents shall also be specifically indicated. The whole of a
referenced document shall not be made applicable by reference unless all of
its provisions are clearly required.
3.2.15 Security marking of specifications. Specifications containing
classified information shall be marked and handled in accordance with current
security regulations as specified in the DOD 5220.22-M.
3.2.16 Identification of specifications. Each specification shall be numbered
and dated on each page. The identification number, with the date below it shall
always appear at the top of the page opposite the binding edge.
This series of specifications shall be identified by the code identification
of the Government design agency as listed in Cataloging Handbook H4 and by a
number assigned by the Government design agency. Such number may be either a
number or a combination of letters, numbers and dashes. The number shall not
contain more than fifteen characters, excluding dashes and revision letter.
Specifications for HWCIs, materials or processes intended for multiple
application may be identified by a military specification number. In such
instances, the number shall be applied in accordance with Defense
Standardization Manual 4120.3-M and no design agency code identification is
used.
3.2.16.2 Identification of contractor specifications. This series of
specifications shall be identified by the manufacturer’s code identification
of the design contractor as listed in Cataloging Handbook H4 and by a number
assigned by the contractor. The assigned number shall not contain more than
fifteen characters, excluding dashes and revision letter.
3.2.16.3 Revision symbols. Revision letters, starting with "A" for the
first revision, and assigned alphabetically for each succeeding revision,
shall follow the specification number. Letters, such as I, O, Z, which can be
confused with numerals shall not be used.
3.2.16.4 Identification of two-part specifications. When a two-part
specification concept (See 3.1.4) is used, the parts shall be identified on
the title page and both parts shall be assigned the same specification number
(See figure 1). Revision status of each part shall be separately
maintained.
3.2.16.5 Identification of specification sheet. The specification sheet is
identified by the same number and code identification, as the associated
applicable general specification followed by a virgule (slant) and a
sequentially assigned Arabic numeral for the sheet. The sheet number shall be
assigned by the contracting agency for the general specification and the total
number of characters for the specification excluding specification sheet
numbers shall not exceed fifteen.
Example: Code Ident 10001 WS 1967B/1A designates revision A of sheet 1 issued
for the B revision of general specification, numbered WS
1967.
3.2.16.6 Designation of FSC Code. If applicable, Federal Supply
Classification (FSC) code shall appear in the lower right-hand corner of the
first page of the specification. FSC codes shall be as assigned in Cataloging
Handbook H2.
3.2.16.7 Titling the specification. The approved basic name of the
material, product or service covered by the specification shall be the first
part of the title.
Configuration item names in titles shall make maximum use of
Cataloging Handbook H6. However, the basic noun in the title
shall be in the singular form if the specification covers only
one product, and in the plural form if the specification
covers more than one product, i.e., various types, grades,
classes, sizes or capacities, etc. except where SPECIFICATION

the only form is plural or where the nature of the product unavoidably
requires the plural form. Where there is no approved configuration item name,
the title shall be developed in accordance with DOD-STD-100. For general
specifications the words "General Specifications For" shall be the closing
phrase of the title.
3.2.16.7.1 Modifiers. The title of the specification shall include, where
appropriate, and in addition to the approved basic name, the minimum number of
modifiers, including Type Designators, as are necessary for distinction and
ready identification of the coverage of the specification. Nondefinitive
modifiers shall not be used. Modifiers shall be arranged in reverse order and
separated from each other and the noun name by punctuation.
3.2.16.8 Type of specification. The type of specification shall be included
above the specification title. As a minimum, the type shall be specified as
"SYSTEM/SEGMENT," "DEVELOPMENT," "PRODUCT," "PROCESS," or "MATERIAL." Subtype
may be specified when desired by the contracting agency.
3.3 CHANGES AND REVISIONS
3.3.1 General. Specifications shall be corrected or updated when necessary,
by means of either a change or revision. A change is accomplished by the issue
of a Specification Change Notice (SCN) and attached change pages. A revision
consists of a complete reissue of the entire specification, all pages being
identified by the same applicable revision letter. In general, corrections to
only a small portion of a specification should be accomplished by a change,
whereas extensive corrections requiring revision occur when: (a) over 50
percent of the pages have been, or will be involved in the intended correction
plus outstanding SCNs; or (b) a revision is economically more practicable than
issue of page changes by SCN. As a general rule, no more than five (5) SCNs
shall be issued against a particular revision (or original issue); when the
sixth modification or correction is required the outstanding changes should
normally be incorporated in a revision of the specification (see 6.2).
3.3.2 Changes. Changes to specifications shall be proposed by SCN and
issued by SCN. Specification sheets shall be changed by revision only. As
required by DOD-STD-480, a separate SCN shall be submitted as an enclosure
with an Engineering Change Proposal (ECP) for each specification to be
changed. SCNs so submitted will be issued and incorporated only after approval
of the ECP and the engineering change ordered. An SCN shall also be used to
issue corrections to a specification unrelated to an ECP (see 6.2).
3.3.2.1 Specification change notice. The SCN is a document used to propose,
transmit and record changes to a specification. The SCN form (figure 2) is
used as a cover sheet and letter of transmittal, the page changes associated
with that SCN shall be attached and shall constitute an integral part of the
SCN (see 6.2).
3.3.2.1.1 Proposed SCN. A proposed SCN shall be used to propose to the
specification approving agency the exact change in specification paragraphs,
figures or other content that will be distributed to users if the SCN is
approved. Such modification in content in this proposed form of the SCN may be
submitted in final specification change form or as an enclosure on which the
proposed changes in sentences, paragraphs, figures, tables, etc., are
described.
3.3.2.1.2 Approved SCN. An approved SCN, is used to transmit the change
after approval by the contracting agency. It also provides a summary of pages
affected by all approved changes. SCNs are not cumulative insofar as
transmittal of previous changes is concerned, and changes distributed with
previous SCNs remain in effect unless changed or canceled by a SCN of later
issue. However, the summary of current changes is a cumulative summary as of
date of approval of the latest SCN.
3.3.2.2 Changed pages. Updated and reissued pages shall be complete
reprints of pages suitable for incorporation by removal of old pages and
insertion of new pages. All portions affected by the change shall be indicated
by a symbol in the right hand margin adjacent to, and encompassing all changed
portions. When change pages are issued for specifications with pages printed
on both sides of a sheet, and only the page on one side of a sheet is affected
by the change, both sides of the sheet shall be reissued. The unaffected page
side shall be reprinted without change and shall not carry the date of the
change or be included in the change summary as being affected by the
change.
3.3.2.3 Change numbering. SCN numbers shall be assigned in sequence,
beginning with 1, against the original issue or current revision of a
specification. Thus, when a specification is revised, the SCN numbers begin
again with 1. The proposed SCN, and approved SCN shall carry the same number.
Once an SCN has been submitted to the contracting agency, its SCN sequence
number shall not thereafter be changed or assigned to another SCN. However,
SCNs may be approved by the contracting agency out of sequence. Hence, an SCN,
proposed after a previously proposed but not yet approved SCN, may require
revision if the later one is approved prior to the earlier one or an earlier
SCN is not approved; in which case the numbers assigned will not change,
however, the contents of the change pages may require a change (see 6.2).
3.3.2.4 Identification and numbering of changed pages.
3.3.2.4.1 Identification. Each changed page shall be identified by means of
the specification number and the applicable revision letter. Under such number
shall be entered the date of issue of the SCN, which shall agree with the date
entered in the upper right hand corner of the SCN
form.
Example: Assume that the current revision of the specification is A, the date
of issue of such revision is 20 June 1966, and two SCNs have been approved. If
SCN-2 is issued on 5 June 1967, the pages changed by SCN-2 would carry the
following identification on each page.
18D4739A
5 June 1967
3.3.2.4.2 Page numbers. The changed pages furnished with an SCN shall be
numbered with the same page numbers as the pages they replace. If it is
necessary to replace one page with more than one, the additional pages shall
carry the same number as the affected page plus a suffix letter in
alphabetical order beginning with "a". Thus, the numbers of changed pages to
change page 5, would be 5, 5a, 5b, etc. If a page is deleted, that number
shall be omitted in the current page sequence.
3.3.3 Revisions. A revision of a specification is a reissue of a complete
specification and shall be prepared, issued, and identified in the same manner
as the specification that it supersedes, except that the identification number
shall be followed by an appropriate revision letter. Letters shall be assigned
in alphabetical order for each succeeding revision. Revision letter "A" shall
be assigned to the first revision. Each revision shall incorporate all
outstanding approved changes against the previous issue as well as approved
changes proposed by the SCN that creates the need for revision. Revisions of
specification will include symbols in the right hand margins of the pages to
indicate where changes have been made with respect to the prior issue,
including changes. The following note will be included in the Notes, Section
6, of the specifications:
"The margins of this specification are marked with a (symbol) to indicate
where changes (additions, modifications, corrections, deletions) from the
previous issue were made. This was done as a convenience only and the
Government assumes no liability whatsoever for any inaccuracies in these
notations. Bidders and contractors are cautioned to evaluate the requirements
of this document based on the entire content irrespective of the marginal
notation and relationship to the last previous
issue."
The following note may be used in lieu of the above, if applicable.
"Symbols are not used in this revision to identify changes with respect to
the previous issue, due to the extensiveness of the changes."
Specification revisions shall be issued in the same manner as the original
issue and do not require an SCN for promulgation (see 6.2).
4. GENERAL REQUIREMENTS FOR SECTIONS OF
SPECIFICATIONS
4.1 Specification 1 - SCOPE. General information pertaining to the extent
of applicability of a configuration item, material or process covered by a
given specification and, when necessary, specific detailed classification
thereof, shall be placed in the appropriate subdivision of Section 1 of
specifications. However, this section shall not contain requirements properly
part of other sections of the specification.
4.1.1 Scope. A statement of the scope shall consist of a clear, concise
abstract of the coverage of the specification and may include, where
necessary, information as to the use of the configuration item other than
specific detailed applications covered under "Intended use" in Section 6 of
the specification. This brief statement shall be sufficiently complete and
comprehensive to describe generally the configuration item, material or
process covered by the specification in terms that may be easily interpreted
by manufacturers, contractors, suppliers, or others familiar with applicable
terminology and trade practices. As applicable,
reference may be made to information contained in Section 6 of
the specification.
4.1.2 Classification. Where a specification covers more than one category
of a configuration item, designations of classification such as types, grades,
classes, etc. shall be listed under this heading and shall be in accordance
with accepted industry practice. The same designation shall be used throughout
the specification. The name of the configuration item covered by the
specification shall be followed by the words "shall be of the following types,
grades, classes, etc., as specified", listing only the applicable
designations. When more than one type, grade, class, etc., is listed, each
shall be briefly defined. When only one (type, grade or other) is covered, a
statement to this effect shall be included in the scope paragraph, and the
classification paragraph omitted. The types, grades, classes, etc., shall not
change when the specification is changed or revised except when industry
practice changes, or for other good reason a change is required. Where the
characteristics of a configuration item change enough to affect
inter-changeability, the original designation shall be deleted and a new type,
grade, class, etc. shall be added. Whenever it becomes necessary to change the
designation without changing the characteristics of the configuration item, a
cross
reference shall be included in Section 6 indicating
the
relationship between the new and old designations. Since such changes may
require cataloging and other record changes, such changes shall be kept to a
minimum.
4.1.2.1 Classification definitions. For the purpose of preparing
specifications, "type," "class," "grade," "composition," and "style" are
defined as indicated below. However, the actual classification used in a
specific specification will be in accordance with accepted practice as
indicated in 4.1.2.
4.1.2.1.1 Type. This term implies differences in like configuration items
or processes as to design, model, shape, etc., and generally will be
designated by Roman numerals, thus "type I," etc.
4.1.2.1.2 Class. This term provides additional categorization of
differences in characteristics other than afforded by type classification that
do not constitute a difference in quality or grade; but are for specific,
equally important uses, and generally will be designated by Arabic numerals;
thus; "class 1," "class 2," etc.
4.1.2.1.3 Grade. This term implies differences in quality of a
configuration item and generally will be designated by capital letters; thus
"grade A," "grade B," etc.
4.1.2.1.4 Composition. This term is used in classifying configuration items
that are differentiated strictly by their respective chemical composition, and
generally will be designated in accordance with accepted trade practice when
satisfactory to the Government design agency.
4.1.2.1.5 Style. This term is used to denote differences in design or
appearance.
4.1.2.1.6 Other classifications. If the terms ‘types,’ ‘grades,’ and
‘classes’ do not serve accurately to classify the differences as indicated
above, other terms such as color, form, weight, size, power supply,
temperature rating, condition, unit, enclosure, rating, duty, insulation,
kind, variety, etc., suitable for reference, may be used.
4.1.2.2 Classification for reliability level identification.
When a specification contains a multilevel reliability requirement, Section 1
of the specification shall identify the levels
covered.
4.2 Section 2 - APPLICABLE DOCUMENTS. All and only those documents referenced
in Section 3, 4, 5 and Appendixes of the specification shall be listed in
Section 2 of the specification. If numerous, Section 2 may reference an appendix
or other appropriate document containing a complete listing. References shall be
confined to documents currently available at the time of issuance of the current
revision of the specification. Figures bound integrally with the specification
shall not be listed in Section 2.
4.2.1 Government documents. Federal and military specifications (as well as
Government design agency specifications), standards, drawings, and other
Government publications may be referenced in specifications. Government
regulations or codes that are mandatory on the military services (such as:
Federal Insecticide, Fungicide, and Rodenticide Act; Drug and Cosmetic Act;
Federal Hazardous Substances Labeling Act; Atomic Energy Act; Department of
Transportation Regulations; and Screw-Thread Standards for Federal Services)
shall be referenced in specifications, where applicable.
4.2.2 Non-Government documents. Reference may be made to non-Government
specifications, standards, and publications promulgated by commercial
organizations, technical societies and other non-Governmental agencies when
such documents are accepted by the using Governmental agency. Care shall be
taken in referencing non-Governmental publications so as to assure the
availability of copies and prior approval of the copyright owner.
4.2.3 Listing of references. References shall be listed by document numbers
and titles, and may include specific issue or revision where necessary to
rigidly control the configuration or implementation of the configuration item,
material or process. The title of each document shall be that appearing on the
document itself rather than that shown in an index.
4.2.3.1 Government documents. Government SPECIFICATIONS STANDARDS,
DRAWINGS, and other PUBLICATIONS intended to be made available to bidders
shall be listed under the appropriate preceding headings and in
alphabetical-numerical order in individual groups, such as Federal, Military,
and Departmental agency (such as Weapons Command, etc.). These listings shall
be included under a paragraph similar to one of the following:
Example 1:
Example 2:
2.1 Government documents. The following documents of the exact issue shown
form a part of this specification to the extent specified herein. In the event
of conflict between the documents referenced herein and the contents of this
specification, the contents of this specification shall be considered a
superseding requirement.
Government documents shall be listed in the following
order:
SPECIFICATIONS:
Federal
Military
Other Government Agency
STANDARDS:
Federal
Military

DRAWINGS:
(Where detailed drawings referred to in a specification are listed on an
assembly drawing, it is only necessary to list the assembly
drawing.)
OTHER PUBLICATIONS:
Manuals
Regulations
Handbooks
Bulletins
etc.
(Copies of specifications, standards, drawings, and publications required by
suppliers in connection with specified procurement functions should be obtained
from the contracting agency or as directed by the contracting officer).
4.2.3.2. Non-Government documents. Non-Government documents shallbe listed
in appropriate order under a paragraph similar to one of the following
subparagraphs:
Example 1:
Example 2:
2.2 Non-Government documents. The following documents of the exact issue
shown form a part of this specification to the extent specified herein. In the
event of conflict between the documents referenced herein and the contents of
this specification, the contents of the specification shall be considered a
superseding requirement.
Non-Government documents shall be listed in the following order:
SPECIFICATIONS:
STANDARDS:
DRAWINGS:
OTHER PUBLICATIONS:
(list source for all documents not available through normal Government
stocking activities.)
The following source paragraph shall be placed at the bottom of the list when
applicable.
"Technical society and technical association specifications and standards are
generally available for reference from libraries. They are also distributed
among technical groups and using Federal agencies."
4.3 Section 3 - REQUIREMENTS. The essential requirements and descriptions
that apply to performance, design, reliability, personnel subsystems, etc. of
the configuration item, material or process covered by the specification shall
be stated in this section. These requirements and descriptions shall define as
applicable, the character or quality of the materials, formula, design,
construction, performance, reliability, transportability, and product
characteristics, chemical, electrical, and physical requirements, dimensions,
weight, color, nameplates, product marking, workmanship, etc. This section is
intended to indicate, as definitively as practicable, the minimum requirements
that a configuration item, material or process must meet to be acceptable. The
Requirements section shall be so written that compliance with all requirements
will assure the suitability of the configuration item, material or process for
its intended purpose, and non-compliance with any requirement will indicate
unsuitability for the intended purpose. Only those requirements shall be
specified that are necessary and practicably attainable.
a. Section 3 of a general specification shall contain all requirements that
are common to a family of systems, configurations items, materials or
processes. When detail specifications are to be prepared to supplement the
general specification to fully define an individual configuration item, etc.,
the following paragraph shall be included in Section 3 of the general
specification:
3.x.x Detail Specification. Requirements for individual
(insert the proper term from among the following) parts,
configuration items, materials, process, systems shall be as
specified herein and in accordance with the applicable detail
specification.
b. Section 3 of a detail specification shall contain the requirements only
for the particular system, configuration item, material or process covered by
that specification. However, if the specification does cover more than one
type, class, grade, etc., it should first specify the general requirements for
all types, classes, grades, etc. The differentiating requirements may then be
specified for the individual types, classes, grades, etc., in the proper
sequence. In general, each requirement shall be covered in a separate
paragraph; and where one requirement differs for the various types, classes,
grades, etc., a separate paragraph immediately following the general
requirements shall be devoted to each type, class, grade, etc. The various
detailed requirements shall be contained in appropriate subparagraphs. Where
it is necessary to include additional data, descriptive and appropriate
headings shall be used and assigned in logical order.
c. Section 3 of system or development specifications (Type A or B) shall
set forth requirements in terms or performance, reliability, design
constraints, functional interfaces, etc., that are necessary to assure a
practical and reasonable development effort. Development specifications may
include design goals in addition to minimum requirements, but in such case,
goals and requirements shall be clearly identified to avoid confusion. Only
essential design constraints shall be included as requirements, such as
restriction of use of certain materials due to toxicity, dimensional or
functional restrictions to assure compatibility with associated equipments,
etc.
d. Section 3 of a product, process or material specification (Type C,D,E)
shall contain all requirements necessary to assure delivery of an acceptable
end product. Requirements in product function specifications shall include
both physical (dimensional and interface characteristics) and performance
requirements in sufficient detail to assure procurement of interchangeable,
but not necessarily identical HWCIs. Requirements in a product fabrication
specification shall include all requirements necessary to assure delivery of
identical HWCIs from suppliers. This is normally accomplished by invoking a
set of drawings (DOD-D-1000 Level 3) as a primary requirement. Product
fabrication specification requirements may also set forth requirements for
performance, reliability, workmanship, etc., when such features or
characteristics are not completely controlled by detail drawings.
4.3.1 Definition. Where applicable, a definition of the system or
configuration item shall be provided in the form of a brief description, and
shall: identify major physical parts, functional areas and functional and
physical interfaces; and shall include system logic diagrams, block diagrams,
schematic diagrams, and pertinent operational, organizational and logistic
considerations and concepts.
4.3.2 Characteristics. Development, product and material specifications,
shall specify all required performance characteristics, physical
characteristics, and requirements for reliability, maintainability,
environmental consideration, and, as appropriate, relative priority of design
disciplines or characteristics.
4.3.2.1 Performance characteristics. These characteristics shall include
general and detail requirements, under appropriate sub-headings, for all
performance requirements, i.e., what is expected of the system, configuration
item, or material.
4.3.2.2 Physical characteristics. These characteristics in a development,
product, or material specification shall set forth requirements such as weight
limits, dimensional limits, etc., necessary to assure physical compatibility
with other elements and not determined by other design and construction
features or referenced drawings. They shall also include considerations such
as transportation and storage requirements, security criteria, durability
factors, health and safety criteria, command control equirements, and
vulnerability factors.
4.3.2.2.1 Protective coating. Where applicable, protective coating
requirements shall be specified under this heading to assure protection from
corrosion, abrasion, or other deleterious action. Where feasible, color and
protective coating should be combined.
4.3.2.3 Reliability. Reliability requirements shall be stated numerically
with confidence levels, if appropriate, in terms of mission success or hardware
mean time between failures. Initially, reliability may be stated as a goal and a
lower minimum acceptable requirement. During contract definition, or equivalent
period, realistic requirements shall be determined and incorporated in the
specification with requirements for demonstration. Reliability requirements
shall never be stated as a goal in Type C (product) specifications.
4.3.2.4 Maintainability. Numerical maintainability requirements shall be
stated in such terms as mean-time-to-repair (MTTR) or maintenance man-hours per
flight/operational hour. Determination of realistic requirements shall be made
as discussed in 4.3.2.3 for reliability. Qualitative requirements for
accessibility, modular construction, test points, and other design requirements
may be specified as required.
4.3.2.5 Environmental conditions. Environments that the system or equipment
is expected to experience in shipment, storage, service, and use shall be
specified. Where applicable, it shall be specified whether the equipment will be
required to meet or be protected against specified environmental conditions.
Subparagraphs shall be included as necessary to cover environmental conditions
such as: climate, shock, vibration, noise, noxious gases, etc.
4.3.2.6 Transportability. Any special requirements for transportability and
materials handling shall be specified under this
heading.
4.3.3 Design and construction. Minimum or essential requirements that are not
controlled by performance characteristics, interface requirements, or referenced
documents shall be specified. They shall include appropriate design standards,
requirements governing the use or selection of materials, parts and processes,
interchangeability requirements, safety requirements, and the like.
4.3.3.1 Materials. Requirements for materials to be used in the item or
service covered by the specification shall be stated under this heading,
except where it is more practicable to include the information in other
paragraphs. Requirements of a general nature should be first, followed by
specific requirements for the material. Definitive documents shall be
referenced for the material when such documents cover materials of the
required quality.
4.3.3.1.1 Toxic products and formulations. Specifications requiring or
permitting toxic products and formulations shall demand compliance with the
requirements of the applicable regulations promulgated by the appropriate
Federal regulatory agency or the official compendia governing such products
and formulations.
4.3.3.2. Electromagnetic radiation. Where applicable, requirements pertaining
to electromagnetic radiation shall be stated in terms of the environment which
the item must accept and the environment which it generates.
4.3.3.3. Nameplates or product markings. The nameplate or markings in some
cases may be the only means of identification of a product after delivery. Such
identification is important from the standpoint of stock, replacements, and
repair parts. All requirements pertaining to nameplates or markings shall be
placed under this, or other appropriate heading, referencing applicable
specifications (e.g., MIL-STD-130), drawings, or standards.
4.3.3.4 Workmanship. Where applicable, reference to workmanship shall be
stated and shall include the necessary requirements relative to the standard of
workmanship desired, uniformity, freedom from defects, and general appearance of
the finished product. This paragraph is intended to indicate as definitively as
practicable the standard of workmanship quality that the product must meet to be
acceptable. The requirements shall be so worded as to provide a logical basis
for rejection in those cases where workmanship is such that the time is
unsuitable for the purpose intended. Generally, no definite tests other than
visual examination of workmanship will be applicable to the requirements of this
paragraph.
4.3.3.5 Interchangeability. This paragraph shall specify the requirements for
the level at which components shall be interchangeable or replaceable. Entries
in this paragraph are for the purpose of establishing a condition of design, and
are not to define the conditions of interchangeability that are required by the
assignment of a part number.
4.3.3.6 Safety. This paragraph shall specify requirements to preclude or
limit hazard to personnel, equipment, or both. To the extent practicable, these
requirements shall be imposed by citing established and recognized standards.
Limiting safety characteristics peculiar to the item due to hazards in assembly,
disassembly, test, transport, storage, operation or maintenance shall be stated
when covered neither by standard industrial or service practices nor the system
specification.
"Fail-safe" and emergency operating restrictions shall be
included when applicable. These shall include interlocks and
emergency and standby circuits required to either prevent injury or provide
for recovery of the item in the event of failure.
reference. This paragraph should also specify any special or
unique requirements, e.g., constraints on allocation or functions to
personnel, and communications and personnel/ equipment interactions. Included,
should be those specified areas, stations, or equipment that require
concentrated human engineering attention due to the sensitivity of the operation
or criticality of the task, i.e., those areas where the effects of human error
would be particularly serious.
4.3.4 Documentation. Where applicable, requirements for documenting the
design shall be specified in general terms in development specifications.
Requirements shall specify types of documents required for design review and
approval, manufacture or procurement, testing, inspection installation,
operation, maintenance, and logistic support as appropriate. This paragraph is
not intended as a requirement for procurement or delivery of data, which shall
be accomplished by use of DD Form 1423.
4.3.5 Logistics. Where applicable, logistic considerations and conditions
that will apply to the system or configuration item shall be specified in
development specifications and, if applicable, in product specifications.
Logistic conditions such as maintenance considerations, modes of
transportation, supply system requirements, and impact on existing facilities
and equipments shall be considered.
4.3.6 Personnel and training. Where applicable, requirements imposed by or
limited by personnel or training considerations shall be specified in
development specifications. Training considerations shall include existing
facilities, equipment, special/emergency procedures (associated with hazardous
tasks) and training simulators, as well as the need for additional facilities,
equipment, and simulators.
4.3.7 Characteristics of subordinate elements. Subsequent paragraphs shall
be added as necessary to system, development, or product specifications to
specify requirements for subordinate elements of the subject system or
configuration item. Requirements for each selected subordinate element shall
be grouped under a major heading titled with the name of the subordinate
element and shall include all of the pertinent types of requirements discussed
in previous paragraphs for the parent system or configuration item.
Requirements imposed directly on the subelement by a requirement on the parent
system or configuration item shall not be repeated.
Allocation or apportionment of a parent system (or configuration item)
requirement may be specified for the subelement. Subelements may be
functionally or physically integrated portions of the parent system (or
configuration item), but would not usually be both in a single
specification.
4.3.8 Precedence. A paragraph shall specify the order or precedence of
requirements; such as, specification over drawings, functional requirements
over physical requirements, adherence to specified processes over other
requirements, etc. The paragraph shall also require that the contractor notify
the contracting agency of each instance of conflicting, or apparently
conflicting, requirements.
Alternatively, this paragraph may specify that the requirements of the
specification shall take precedence over referenced documents. In system or
development specifications, this paragraph shall specify the relative
importance of requirements (or goals) to be achieved by the design.
4.3.9 Qualification. Qualification, as used in this Standard, refers to the
verification or validation of item performance in a specific application. This
qualification results from design review, test data review, and configuration
audits. Where performance qualification of a design or an end configuration
item (including its components) is required, either on a one-time basis or a
periodic basis, to achieve design approval, proof of producibility, assessment
of production or other reason, provisions for such qualification testing shall
be stated in this paragraph. Requirements shall be included which state the
conditions for testing, the time (program phase) of testing, period of
testing, number of units to be tested, and other requirements relating to
qualification or requalification.
Qualification, as used in Defense Standardization Manual 4120.3-M, refers
to the testing or review of test data to judge configuration items from
various sources as being suitable for general application, and is intended to
lead to the establishment of a Qualified Products List (QPL). Therefore, this
type of qualification is subject to the provisions of Manual 4120.3-M and is
not within the scope of this Standard.
4.3.10 Standard sample. A standard sample is one considered essential to
supplement or illustrate certain requirements of the specification. Use of
standard samples should be kept to a minimum, since their use can create
problems in determining the acceptability of HWCIs subsequently produced.
Adequate inspection requires that all requirements be made available such as
the approved tolerances of dimensions, performance, etc. A standard sample
does not provide all this information but must be supported by specification
requirements and drawings. The use of the standard sample shall be limited to
the illustration of qualities and characteristics that cannot be readily
described because detailed test procedures or design data are not available,
or because certain qualities and characteristics cannot be definitely
expressed, such as the texture of fur, the color of cloth, or the grain of
wood. Further, the specification should state the specific characteristics and
the degree to which these characteristics are to be observed in the standard
sample. When a standard sample is to be furnished, it shall be so stated in
Section 3.
Means of obtaining or viewing standard samples shall
be
specified in Section 6.
4.3.11 Preproduction sample, periodic production sample, pilot, or pilot
lot. Where it is essential that a preproduction or periodic production sample,
a pilot model, or a pilot lot be tested for design approval prior to or during
regular production on a contract or order, the requirements shall be specified
in this section under the appropriate paragraph identification.
4.4. Section 4 - QUALITY ASSURANCE PROVISIONS.
For software, this section shall be titled Qualification
Requirements and shall specify the qualification requirements,
including methods, levels of testing, tools, facilities, test
formulas, algorithms, and acceptance tolerance limits required
to show that the requirements stated in Section 3 and 5 have
been met. The Software Requirements and Interface
Requirements Specification Data Item Descriptions contain
further information for specifying qualification requirements
(See 6.2). For software embedded in firmware devices, the application of
quality assurance provisions or requirements depends on whether the software is
designated as a CSCI or part of an HWCI. When the software is designated as a
CSCI, Qualification Requirements apply, but when designated as part of an HWCI,
Quality Assurance Provisions apply. For hardware, this section shall include all
of the examinations and tests (by reference where applicable) to be performed in
order to ascertain that the product, material or process to be developed or
offered for acceptance conforms to the requirements in Sections 3 and 5 of the
specification.
Section 4 shall be arranged in an orderly sequence which will
indicate clearly which inspections (examinations and tests)
apply directly to the process, material, HWCIs, or lots of
HWCIs that were developed or produced and which apply to
requirements such as evaluation, qualification (See 4.3.9),
preproduction sample, pilot model, or pilot lot. The
order
of presentation of Section 4 material shall, insofar as practicable, follow
the order of requirements as presented in Section 3 of the specification, or
alternatively in the most logical order of conducting the examinations and
tests listed.
4.4.1 General. Where applicable, the general test and inspection philosophy
shall be described with a statement of responsibility for inspection,
classification of examinations and tests, sampling, lot formation, and other
information pertinent to the quality assurance provisions but not directly
associated with a specific test or examination.
4.4.1.1 Responsibility for inspection. The DOD concept of quality assurance
places primary responsibility for quality assurance of delivered products,
materials or services on the supplier who is responsible for offering to the
contracting agency only those products, materials or services that conform to
all specified requirements. In system specifications, however, where assembly
of the system/segment is at a Government facility or on a Government-owned
vessel involving Government-furnished property and personnel, responsibility
for the conduct of tests will probably be split between the contracting agency
and the contractor. Accordingly, the supplier’s responsibility for inspection
shall be clearly stated and the contracting agency’s role, either as a partner
or monitor, shall be specified. A typical statement of responsibility is as
follows:
4.1.1 Responsibility for inspection. Unless otherwise specified in the
contract or order, the supplier is responsible for the performance of all
inspection requirements as specified herein. Except as otherwise specified,
the supplier may utilize his own facilities or any commercial laboratory
acceptable to the contracting agency. The contracting agency reserves the
right to perform any of the inspections set forth in the specification where
such inspections are deemed necessary to assure supplies and services conform
to prescribed requirements.
4.4.1.2 Special tests and examinations. Any special tests and examinations or
associated actions required for sampling, lot formation, qualification
evaluation, etc., shall be covered under an appropriate heading, for
example:
4.1.2 Preproduction sample, pilot model, or pilot run. When Section 3
specifies a requirement for preproduction sample, pilot model, or pilot run,
Section 4 shall include under an appropriate identification, a description of
the testing routine, sequence of tests, number of units to be tested, data
required, and the criteria for determining conformance to specified
requirements.
4.1.2 Qualification provisions. When the requirements for HWCIs covered in
Section 3 contain a qualification provision, the applicable examinations and
tests shall be listed under appropriate headings in Section 4.
These inspections shall be specified for initial and higher
levels (reliability levels) of qualification including the test
methods for continuous testing, and periodic qualification
re-evaluation as covered in Section 3 of the specification.
When a tabular form of presentation will provide a better understanding of
the correlation between tests of Section 4 and requirements of Section 3, or
would clarify the test requirements for acceptance, performance, qualification,
preproduction, etc., a tabular presentation similar to that below shall be
made.

4.4.2 Quality conformance inspections. This section shall list all
examinations and tests required to verify that all requirements of Section 3
and 5 have been achieved in the HWCI, material, or process offered for
acceptance. These examinations, and tests shall include, or reference as
appropriate:
a. Tests and checks of the performance and reliability requirements.
b. A measurement of comparison of specified physical characteristics.
c. Verification, with specific criteria, for workmanship.
d. Test and inspection methods for assuring compliance, including
environmental conditions for performance.
e. Classification of characteristics as critical, major or minor, as
defined in MIL-STD-109. When required for
reference purposes in reporting inspection results,
the
characteristics may be numbered. When numbered, numbers shall be in
accordance with the following:
1 through 99 - critical characteristics
101 through 199 - major characteristics
201 through 299 - minor characteristics
4.5 Section 5 - PREPARATION FOR DELIVERY. This section is generally
applicable to product specifications only, and shall include applicable
requirements for preservation, packaging, and packing the configuration item,
and markings of packages and containers.
4.5.1 General. This section shall state the general requirements for
preservation, packaging, packing, and package marking. If more than one level
of preservation and packaging is included, the conditions for selection of
levels shall be explained. See FED-STD-102.
4.5.2 Specific requirements. The specific requirements for materials to be
used in preservation, packaging, and packing a product shall be covered in
Section 5, either directly or by
reference to other specifications, publications, or drawings.
reference to other specifications and applicable standards or,
where these do not exist or are not applicable, by detailed
instructions. The requirements shall be included with
appropriate headings, as required, for disassembly, cleaning,
drying, preservation, packaging, packing, and shipment
marking. These requirements shall be specifically related to
each required level of preparation in a manner which will
leave no doubt regarding requirements applicable to such
level. Detailed preparation for delivery
requirements
should be covered as far as practicable in four basic categories, as
follows.
4.5.3.1 Preservation and packaging. The requirements for preservation and
packaging shall cover cleaning, drying, and preservation methods adequate to
prevent deterioration, appropriate protective wrapping, package cushioning,
interior containers, and package identification-marking up to but not
including, the shipping container. Where no suitable
reference is available, step-by-step procedures for
preservation and packaging shall be included.
4.5.3.2 Packing. The requirements for packing shall cover the exterior
shipping container, the assembly of configuration items or packages therein,
necessary blocking, bracing, cushioning, and weatherproofing.
4.5.3.3 Marking for Shipment. Normally, marking requirements shall be
established by reference to MIL-STD-129. Markings essential to safety and to
the protection or identification of the configuration item which are not
required by MIL-STD-129, or are required on a "When specified" basis by that
standard, shall be specified in detail under this heading. In any instance
where reference to MIL-STD-129 is not applicable, requirements in detail or by
reference to recognized documents shall include: appropriate identification of
the product, both on packages and shipping containers; all markings necessary
for delivery and for storage, if applicable; all markings required by
regulations, statutes, and common carriers; and all markings necessary for
safety and safe delivery.
4.6 Section 6 - NOTES. Section 6 of specifications shall contain
information of a general or explanatory nature, and no requirements shall
appear therein. It shall contain information, not contractually binding,
designed to assist in determining the applicability of the specification and
the selection of appropriate type, grade, or class of the configuration item,
such as additional supersession data, changes in product designations (grades,
class, etc.), standard sample (if required), etc. This section should include
the following, as applicable, in the order listed:
Intended use
Ordering data
Preproduction sample, pilot model, or pilot lot, if any
Standard sample, if any
Definitions, if any
Qualification provisions
Cross reference of classifications
Miscellaneous notes
4.6.1 Intended use. Information relative to the use of the configuration item
covered by the specification should be included under this heading. The
difference among types, grades, and classes in the specification shall be
explained herein. If particular applications exist for which the material is not
well adapted, this information also may be included.
4.6.2 Ordering data. Detailed information to be incorporated in invitations
for bids, contracts, or other purchasing documents shall be stated in this
paragraph. Reference shall be made to all parts of the specification where it is
required that options be exercised, such as requirements for preproduction
sample for qualification, selection of grade, type, class, level of preservation
and packaging, etc. When helpful, further information shall be furnished.
4.6.3 Instructions for models and samples.
4.6.3.1 Instructions for preproduction sample, pilot model, etc. If Section
3 specifies a preproduction sample, a pilot model, or a pilot lot, the
necessary instructions for the arranging for its examination, test, and
approval shall be stated in this section under an appropriate paragraph
identification.
4.6.3.2 Standard sample. If Section 3 specifies a standard sample,
information for obtaining or examining the standard sample (source and
address) shall be stated under this paragraph identification.
4.6.4 Qualification provisions. Where provisions for qualification of a
product is a requirement of the specification, information concerning such
qualification shall be stated in this section.
4.6.5 Cross-reference of classifications. A cross-reference of old to new
classification (types, grades, classes, etc.) of configuration item, material or
service shall be included if such changes are made by specification revision. If
new classes, grades or types or configuration items or materials are being added
to, and others are being removed from, the coverage of the specification, a
cross-reference showing substitutability relationships shall be included.
4.7 APPENDIX AND INDEX
4.7.1 General. Where required, Appendixes and an Index may be included as
an integral part of a specification.
4.7.2 Appendix. An appendix, identified by the heading ‘APPENDIX’, is a
section of provisions added at the end of a specification. An appendix may be
used to append large (multi-page) data tables, plans pertinent to the
submittal of the configuration item, management plans pertinent to the subject
of the specification, classified information or other information or
requirement related to the subject configuration item, material or process
that would normally be invoked by the specification but would, by its bulk or
content, tend to degrade the usefulness of the specification. In all cases
where an appendix is used, reference to the appendix shall be included in the
body of the specification.
4.7.2.1 Numbering. Appendixes to a specification shall be numbered as
Sections 10, 20, etc. in multiples of 10 for each succeeding appendix.
Divisions and paragraphs within an appendix shall be numbered, such as 10.1,
10.1.1, etc. Page numbers for the appendixes normally will be consecutive and
in sequential order with the page numbers used throughout the specification.
Each page of the appendix shall be identified with the specification number as
in the specification.
4.7.2.2 Scope. An appendix shall have a statement of scope to indicate the
limitations of the appendix and to insure its proper application and use.
4.7.2.3 Headings. Headings should be used as necessary, but need not
duplicate the structure of the specification of which the appendix is a
part.
4.7.2.4 References. References which may be required and which relate to
the appendix shall be listed in Section 2 of the basic specification and may
also be listed in a section of applicable documents in the appendix
itself.
4.7.3 Index. An alphabetical index may be placed at the end of a
specification to permit ready reference to contents. Its use shall be limited to
lengthy specifications.
5. DETAIL REQUIREMENTS
5.1 General. Detail requirements for the various types and subtypes of
specifications are contained in Appendixes I through XV. Requirements for any
configuration item, material, or process that do not properly fall under a
paragraph number or title in the applicable appendix may be added as
additional paragraphs in the appropriate section. If the outline of the
applicable appendix is not made mandatory by contract provisions (Form 1a),
the additional paragraphs may be inserted at any point in the proper section,
and paragraph headings and numbers not applicable may be omitted.
If the outline of the applicable appendix is made mandatory by
contract provisions, additional necessary requirements
headings shall be inserted at the end of the proper section,
except for Types A and B1, where such requirements shall be
inserted between 3.6 and 3.7 (3.7 and subsequent paragraphs
being suitably renumbered), for requirements limited to a
single functional area or major component. The notation "Not
applicable" shall be entered after each paragraph number and title that is
not applicable. Subordinate paragraph headings may be added under the most
suitable major paragraph heading in the outline prescribed by any appendix.

This paragraph shall list the Government furnished property required for
fabrication of the prime item. This list shall identify the property by
reference to its nomenclature, specification number and part number. If the
list is extensive, it may be included in an appendix, which shall be
referenced in this paragraph.
80.3.2 Paragraph 3.2, Characteristics.
80.3.2.1 Paragraph 3.2.1, Performance. This paragraph shall include those
performance requirements that are to be demonstrated by the quality
conformance inspections in Section 4 of the specification. It may also include
requirements for performance, reliability, etc., when such requirements are
not completely controlled by drawings. In no instance should contradicting
requirements be specified.
All requirements included herein shall, in most cases and as excepted by
80.3.4, be limited to performance at environmental conditions normal to the
place of acceptance and shall not attempt to simulate service environment.
Requirements included herein shall be specified in physically measurable
quantitative terms with tolerances. Such performance shall be in terms of the
prime item itself without reference to equipments or facilities with which it
must be compatible.
80.3.3 Paragraph 3.3, Design and construction. This paragraph shall include
any essential requirements that are not controlled by the drawings or
referenced documents.
80.3.3.1 Paragraph 3.3.1, Production drawings. This paragraph shall contain
a statement similar to the following: "This (prime item name) shall be
fabricated and assembled in accordance with the drawings, parts lists, and
other documents listed on (insert identification of data lists, index lists,
parts lists or top drawing depending on which is the highest level listing of
the applicable data)."
80.3.3.2 Paragraph 3.3.2, Standards of manufacture. This paragraph shall
include those standards or essential processes that, because of their
significance, must be set forth as a requirement for the manufacture of the
prime item. Requirements specified herein shall be to the level of detail
necessary to clearly establish limits for the inspections included in Section
4 of the specification.

(*)80.3.4 Paragraph 3.4, Preproduction sample. (See 4.3.11) This paragraph,
if appropriate, shall specify that a preproduction sample(s) shall be tested
prior to regular production to demonstrate the adequacy and suitability of the
contractor’s processes and procedures in achieving the performance that is
inherent in the design. Whereas in a function specification the purpose of
preproduction tests is to provide a basis for design approval, in a fabrication
specification preproduction tests, like periodic production tests, are intended
to show that the manufacturing and production techniques employed do not degrade
the design. Preproduction tests in a fabrication specification are particularly
necessary when a contract is awarded to a new source that has not previously
produced the prime item. Selected performance requirements in the service
environment may be added to paragraph 3.2 of a fabrication specification to
provide requirements upon which preproduction tests in Section 4 of the
specification are to be based. However, since all such performance requirements
should be in the development specification for the prime item, it will reduce
the bulk of the fabrication specification if performance requirements in the
service environment are invoked by referencing the associated development
specification. In addition, the titles and requirements of this paragraph may be
made to cover samples for periodic production tests if such tests are considered
necessary.
80.4 Section 4, Quality Assurance Provisions. Requirements for formal
tests/verifications of the prime item performance and physical characteristics
shall be specified in this section. In general, this section shall conform to
the requirements of 4.4.

in section 4, such as location or conditions for preproduction and periodic
production testing, requirements for special testing of prime item components,
etc.
80.4.1.1 Paragraph 4.1.1, Responsibility for inspection. This paragraph
shall usually state that the responsibility for performing all specified
tests/verifications rests with the supplier, and that the contracting agency
reserves the right to witness or separately perform all tests specified or
otherwise inspect any or all tests and inspections.
80.4.1.2 Paragraph 4.1.2, Special tests and examinations.
This paragraph shall cover the testing routine, sequence of tests, number
of prime items to be tested, data required, etc. for all testing requirements
for other than acceptance inspection. It shall also include, preferably in
tabular form, a correlation between each requirement, its test, and the type
of unit on which the test shall be performed.

80.6.1 Paragraph 6.1, Intended use. (See 4.6.1)
80.6.2 Paragraph 6.2, Ordering data. (See 4.6.2) This paragraph shall
contain the following:
a. If preproduction inspection is specified, a paragraph shall be provided
suggesting the number of samples to order for such tests. The ordering of
samples for preproduction tests may be limited to contracts awarded to new
sources with no previous production or development experience on the prime
item. Disposition of the preproduction models after testing should be covered,
e.g., replace all damaged parts and deliver for service use, scrap, or hold
for use in future development programs, etc.
b. If preproduction tests are based on requirements in a development
specification (Type B1), the fact that the development specification as well
as this specification must be supplied to bidders should be stated.
80.7 Section 10, Appendix I. This section of the specification shall contain
requirements which are contractually a part of the specification but which, for
convenience in specification maintenance, are incorporated herein, e.g.,
requirements of a temporary nature or for limited effectivity. Appendixes may be
bound as separate documents for convenience in handling, e.g., where only a few
parameters of the prime item are classified, an appendix containing only the
classified material may be established. Where parameters are placed in an
appendix, the appropriate paragraph of Section 10 shall be referenced in the
main body of the prime item specification in the place where the parameter would
normally have been specified.

number. If the list is extensive, it may be included in an appendix which
shall be referenced in this paragraph.
100.3.2 Paragraph 3.2, Characteristics.
100.3.2.1 Paragraph 3.2.1, Performance. This paragraph shall include those
performance requirements which are to be demonstrated by the quality
conformance inspections in Section 4 of the specification. It may also include
requirements for performance, reliability, etc., when such requirements are
not completely controlled by detail drawings. In no instance should
contradicting requirements be specified. All requirements included herein
shall, in most cases, be limited to performance at environmental conditions
normal to the place of acceptance and shall not attempt to simulate service
environment. Requirements included herein shall be specified in physically
measurable quantitative terms with tolerances. Such performance shall be in
terms of the critical item itself without reference to equipments or
facilities with which it must be compatible.
(*) (Omit if not applicable)
100.3.3 Paragraph 3.3, Design and construction. This paragraph shall include
any essential requirements that are not controlled by the drawings or referenced
documents.

"This (critical item name) shall be fabricated and assembled in accordance
with the drawings, parts list, and other documents listed on (insert
identification of data lists, index lists, parts lists or top drawing
depending on which is the highest level listing of the applicable data)."
100.3.3.2 Paragraph 3.3.2, Standards of manufacture. This paragraph shall
include those standards or essential processes that, because of their
significance, must be set forth as a requirement for the manufacture of the
critical item. Requirements specified herein shall be to the level of detail
necessary to clearly establish limits for the inspections included in Section
4 of the specification.
100.3.3.3 Paragraph 3.3.3, Workmanship. This paragraph shall specify the
general requirements for workmanship that are incident to the manufacture of the

cover:
a. Burrs and sharp edges
b. Presence of foreign matter
c. Uniformity and general appearance.
(*)100.3.4 Paragraph 3.4, Preproduction sample. (See 4.3.11)
This paragraph, if provided, shall specify that a
preproduction sample(s) shall be tested prior to regular
production to demonstrate the adequacy and suitability of the
contractor’s processes and procedures in achieving the
performance that is inherent in the design. Although in a
function specification, the purpose of preproduction tests is
to provide a basis for design approval, in a fabrication
specification preproduction tests, like periodic production
tests are intended to show that the techniques employed do not
degrade the design. Preproduction tests in a fabrication
specification are particularly necessary when a
contract is awarded to a new source that has not previously produced the
critical item. Selected performance requirements in the service environment
may be added to paragraph 3.2 of a fabrication specification to provide
requirements upon which preproduction tests in Section 4 of the specification
are to be based. However, since all such performance requirements should be in
the development specification for the critical item, it will reduce the bulk
of the fabrication specification if performance requirements in the service
environment are invoked by referencing the associated development
specification. In addition, the titles and requirements of this paragraph may
be made to cover samples for periodic production tests if such tests are
considered necessary.
100.4 Section 4, Quality Assurance Provisions. Requirements for formal
tests/verifications of the critical item performance and physical
characteristics shall be specified in this section. In general, this section

all specified tests/verifications rests with the supplier, and that the
Government reserves the right to witness or separately perform all tests
specified or otherwise inspect any or all tests and inspections.
100.4.1.2 Paragraph 4.1.2, Special tests and examinations.
This paragraph shall cover the testing routine, sequence of tests, number of
critical items to be tested, data required, etc. for all testing requirements
for other than acceptance inspection. It shall also include, preferably in
tabular form, a correlation between each requirement, its test, and the type of
unit on which the test shall be performed.
