evaluation of most types of redundancy design configurations with which a
reliability engineer is faced. The
report contains a number of alternative evaluation approaches, both classical
and unique. Closed form results and
algorithms are derived for the evaluation of the reliability of various types
of redundant configurations.
DOD3235.1H Test & Evaluation of System Reliability, Availability, and
Maintainability—A Primer ,
March 1982. 287 Pages.
The purpose
of this primer is to provide instruction in the analytical assessment of system
reliability, availability, and maintainability (RAM) performance. This text presents concepts and techniques
for designing test plans which can verify that previously established system
suitability requirements have been achieved.
Test resource availability may be adversely affected by cost, schedule
and operational urgency constraints. In
such cases, alternate test plans which represent the most meaningful, timely
and cost effective approach, consistent with these constraints, must be
develop. It is essential that all
participants understand the critical issues being addressed and the acquisition
risks inherent in conducting a limited test program. The design and execution of sound test
programs is no accident. It requires
numerous hours of research and planning and a thorough understanding of testing
techniques, the test system and its operating scenario. Further, the test results must support the
development of realistic performance estimates for the entire production run,
after having tested relatively few systems.
Herein lies the usefulness of the statistical
concepts contained in this text. Topics
addressed in this text will familiarize the reader with the statistical
concepts relevant to test design and performance assessment. In short, these topics, when combined with
common sense and technical expertise formulate the basis of all sound test
programs.
DOD-HDBK-791 Maintainability
Design Techniques, March 1988. 232
Pages
The
purpose of this handbook is to provide Army design engineers with guidelines to
assist them in incorporating maintainability into
Army materiel early in research and development. Information collected from maintenance
records provides practical examples—good and bad—that illustrate the design
principles that result in maximum maintainability. The designer can use these principles to
build maintainability into materiel and thereby contribute substantially to
solving the Army’s maintenance problem.
Chapter
1 is an introduction to the principle of maintainability, its importance, and
methods of achieving it. The following
10 chapters refer to simplification, standardization and interchangeability,
accessibility, modularization, identification and labeling, testability and
diagnostics techniques, prevention maintenance, human factors, and
environmental factors—describe in detail their role in achieving the
maintainability principles.
Data
includes ergonomic details.
DOE-NE-STD-1004-92 Root Cause Analysis Guidance Document, February 1992. 69 Pages.
DOE Order
5000.3A, “Occurrence Reporting and Processing of Operations Information,”
requires the investigation and reporting of occurrences (including the performance
of root cause analysis [RCA]) and the selection, implementation, and follow-up
of corrective actions. The level of
effort expended should be based on the significance attached to the occurrence. Most off-normal occurrences need only a
scaled-down effort while most emergency occurrences should be investigated
using one or more of the formal analytical models. A discussion of methodologies, instructions,
and worksheets in this document guides the analysis of occurrences as specified
by DOE Order 5000.3A.
DOD-STD-1701(NS) Hardware Diagnostic Test System Requirements, June 1985, Pages 11 (This is NOT an authentic copy)
This
document establishes the general procedures, terms and conditions governing the
preparation and completion of a hardware diagnostic test system (HDTS). The purpose of this Standard is to establish
the development criteria for the preparation and completion of the hardware
diagnostic test system for systems, subsystems, and equipments.
DOD-STD-2167A Defense System Software
Development, February 1988, Pages 49
This
standard establishes uniform requirements for software development that are applicable
throughout the system life cycle. The
requirements of this standard provide the basis for Government insight into a
contractor’s software development, testing and evaluation efforts.
This
standard is not intended to specify or discourage the use of any particular
software development method. The
contractor is responsible for selecting software development methods (for
example, rapid prototyping) that best support the achievement of contract
requirements.
This
standard, together with the other DOD and military documents referenced in
Section 2, provides the means for establishing, evaluating, and maintaining
quality in software and associated documentation.
Data
Item Descriptions (DIDs) applicable to this standard
are listed in Section 6. These DIDs describe a set of documents for recording the
information required by this standard.
Production of deliverable data using automated techniques is encouraged.
Per
DODD 5000.43, Acquisition Streamlining, this standard must be appropriately
tailored by the program manager to ensur that only
cost-effective requirements are cited in defense solicitations and
contracts. Tailoring guidance can be
found in DOD-HDBK-248, Guide for Applicable and Tailoring of Requirements for
Defense Material Acquisitions.
The
predecessor document
is available. Also available is the cancellation
document. The referenced document MIL-STD-498 is
also available along with the cancellation
document.

review of Criticality Safety Evaluations across the DOE complex and compliance
with either DOE Order 5480.24 or DOW Order 420.1 requirements.
MIL-HDBK-5 Metallic Materials And Elements For Aerospace
Vehicle Structures, Rev MIL-HDBK-5H, 1 December 1988. 1653 pages (37 Meg PDF file size!)
[Metallic
Materials Properties Development and Standardization (MMPDS) prepared by
Battelle makes MIL-HDBK-5 obsolete and MMPDS-03 is the current version
available in 6 volumes for US$599 for hard copy or US$499 for downloads—please
note MMPDS-03 is covered under US Copyright—see http://mmpds.org
for further information.]
MIL-HDBK-5H
is intended primarily as a source of design allowables,
which are those strength properties of metallic materials and elements
(primarily fasteners) that are widely used in the design of aerospace
structures. These metallic materials
include all systems potentially useful in aerospace and aircraft applications,
including those involving reinforcing components. This document also contains information and
data for other properties and characteristics, such as fracture toughness
strength, fatigue strength, creep strength, rupture strength, fatigue-crack
propagation rate, and resistance to stress corrosion cracking. The use of this type of information is not
mandatory.
In
addition to the properties of the materials and elements themselves, there are
some of the more commonly used methods and formulas by which the strengths of
various structural elements or components are calculated. In some cases, the methods presented are
empirical and subject to further refinements.
MIL-HDBK-H108 Sampling Procedures And Tables For Life And Reliability Testing (Base
on Exponential Distribution), April 1960. 78 Pages
This
handbook has been prepared to meet a growing need for the use of standard
sampling procedures and tables for life and reliability testing in Government
procurement, supply, and maintenance quality control operations as well as in
research and development activities where applicable.
A
characteristic feature of most life tests is that the observations are ordered
in time to failure. If, for example, 20
radio tubes are placed on life test, an t1
denotes the time where the ith tube fails,
the data occur in such a way that t1≤t2≤…≤ t20. The same kind of ordered observations will
occur whether the problem under consideration deals with the life of electric
bulbs, the life of electronic components, the life of all bearings, or the
length of life of human beings after they are treated for a disease. The examples just given all
involved ordering in time.
In
destructive testing involving such situations as the current needed to blow a
fuse, the voltage needed to break down a condenser, the force needed to rupture
a physical material, the test can often be arranged in such a way that every
item in the sample is subjected to precisely the same stimulus (current,
voltage, stress). If this is done, then
clearly the weakest item will be observed to fail first, the second weakest
next, etc. While the random variable
considered mostly in this handbook is time to failure, it should be emphasized,
however, that the methodology provided herein can be adopted
to the testing situations mentioned above where the random variable is current,
voltage, stress, etc.
MIL-HDBK-189 Reliability Growth Management, February 1981. 155 Pages.
This handbook
provides procuring activities and development contractors with an understanding
of the concepts and principles of reliability growth, advantages of managing
reliability growth, and guidelines and procedures to be used in managing
reliability growth. It should be noted
that this handbook is not intended to serve as a reliability growth plan to be
applied to a program without any tailoring.
This handbook, when used in conjunction with knowledge of the system and
its development program, will allow the development of a reliability growth
management plan that will aid in developing a final system that meets its
requirements and lowers the life cycle cost of the fielded systems. [This
document describes the Duane method of reliability growth and becomes the Duane
AMSAA methodology which today is described as the Crow-AMSAA reliability growth
model.]
MIL-HDBK-217F Reliability Prediction Of
Electronic Equipment, January 1990. 205 Pages.
The
purpose of this handbook is to
establish and maintain consistent and uniform methods for estimating the
inherent reliability (i.e., the reliability of a mature design) of military
electronic equipment and systems. It provides
a common basis for reliability predictions during acquisition programs for
military electronic systems and equipment.
It also establishes a common basis for comparing and evaluating
reliability predictions of related or competitive designs. The handbook is intended to be used as a tool
to increase the reliability of the equipment being designed.
The application of this handbook contains two methods of reliability
prediction – “Part Stress Analysis” in Sections 5 through 23 and “Parts Count”
in Appendix A. These methods vary in
degree of information needed to apply them.
The
MIL-HBK-251 Reliability/Design Thermal Applications, January
1978, 697 Pages. (54 Meg file size!)
This
handbook has been prepared specifically to guide engineers in the thermal
design of electronic equipment with improved reliability. The primary purposes are: to permit engineers
and designers, who are not heat transfer experts, to design electronic
equipment with adequate thermal performance with a minimum of effort; to assist heat transfer experts, who are not
electronic experts; to aid designers in better understanding the thermal
selection of Department of Defense specification and standards for equipment;
and to assist Navy personnel in evaluating thermal design during the various
stages of equipment procurement and development.
This
handbook recommends and presents electronic parts stress analysis methods which
lead to the selection of maximum safe temperatures for parts so that the
ensuing thermal design is consistent with the required equipment
reliability. These maximum parts
temperatures must be properly selected since they are the goals of the thermal
design, a fact with is often overlooked.
Many thermal designs are inadequate because improper maximum parts
temperatures were selected as design goals.
Consequently, the necessary parts stress analysis procedures have been
emphasized.
MIL-HDBK-259 Life Cycle Cost In
Navy Acquisitions, April 1983. 71 Pages.
This handbook provides basic
information on life cycle cost analysis as a management tool for controlling
and reducing total costs. The emphasis
is on what the life cycle cost techniques are rather than on how to implement
them. The intent is to furnish an
overview of the points to address and the procedures to use when performing
life cycle cost analysis so that the analyst, wheter
government or contractor, will be better able to conform to the acquisition
manger’s objectives. Without going into
great depth, those issues of most interest to the beginner are discussed, thus
making this handbook particularly used as an initial step in learning about and
understand life cycle cost in Navy acquisitions. These issues are:
a. what is life cycle cost
b. what are the objectives and requirements of
life cycle cost
c.
what costs are relevant and significant
d.
what are the analysis procedures
e.
what data sources and estimating techniques
should be used
f.
when and how to choose or develop a
computerized model
Experience has show that these are the most
pressing questions for those who are undertaking their first life cycle costing
effort, and a document which addresses these questions can, in some measure,
help to instill a cost management discipline which will result in more
efficient cost reduction and cost control efforts in Navy acquisitions.
MIL-HDBK-263B Electrostatic
Discharge Control Handbook For Protection Of
Electrical And Electronic Parts, Assemblies and Equipment (Excluding
Electrically Initiated Explosive Devices), July 1994. 171 Pages.
This
handbook provides guidance, not mandatory requirements, for the establishment
and implementation of an Electrostatic Discharge (EDS) Control Program in
accordance with the requirements of MIL-STD-1686. This document is applicable to the protection
of electrical and electronic parts, assemblies and equipment from damage due to
ESD. It does not provide information for
the protection of electrically initiated explosive devices.
Various
segments of industry are aware of the damage static electricity can impose on
metal oxide semiconductor (MOS) parts.
The sensitivity of other parts to electrostatic discharge damage has
also become evident through use, testing, and failure analysis. Trends in technology utilizing new materials,
processes and design techniques, including increased packaging densities result
in some parts being more susceptible to ESD.
Electrical
and electronic parts which have been determined to be ESD sensitive (ESDS)
include: microelectronic discrete and integrated semiconductor devices; thick
and thin film resistors, chips and hybrid devices; and piezoelectric
crystals. Subassemblies, assemblies and
equipment containing these parts are also ESDS.
Materials
which are prime generators of electrostatic voltages include, but are not
limited to, common plastics such as polyethylene, vinyls,
foam, polyurethane, synthetic textiles, fiberglass, glass, rubber, and other
commonly used materials. Damaging
electrostatic voltage levels are commonly generated by contact and subsequent
separation of these materials by industrial processes and personnel movement.
MIL-HDBK-276-1 Life Cycle Cost Model For Defense Materiel Systems Data Collection
Workbook, February 1984. 407 Pages.
This handbook describes the elements
to be considered in determining the life cycle cost of a materiel system. These cost elements and cost factors form the
input and output structure of the Life Cycle Cost Model for Defense Materiel
Systems. The handbook is meant to be a
workbook for determining life cycle costs.
Normally, a subset of the cost structure contained in this handbook and
the Model will be prescribed for any given procurement. The emphasis is on what costs should be
considered in developing life cycle cost estimates for controlling and reducing
total costs. The handbook and the Model
are specifically designed to give the analyst and the program manger complete
control over the subset of the Model’s cost elements which is applicable to the
system being costed and to select the most
appropriate cost estimating methodology for each cost element.
MIL-HDBK-287 A

MIL-HDBK-344A Environmental
Stress Screening (ESS) Of Electronic Equipment, August 1993 102 Pages.
This
Handbook provides uniform procedures, methods and techniques for planning,
monitoring and controlling the cost effectiveness of ESS programs for
electronic equipment. It is intended to
support the requirements of MIL-STD-785,
Task 301, “Environmental Stress Screening” and/or MIL-STD-781,
Task 401, “Environmental Stress Screening: and to implement Air Force R &M
2000 ESS recommendations and guidelines.
The
Handbook is intended for use by procuring activities and contractors during
development and production. It is not
intended that the Handbook procedures and techniques be used in a cookbook
fashion. Knowledge of the equipment and
the manufacturing process is essential for a properly planned and tailored ESS
program. The data base needed for a
systematic approach to ESS application is not fully developed. Use of the Handbook by Government procuring
agencies and equipment manufacturers will foster the development of an improved
and broader data base.
A
properly applied ESS program can significantly impact the quality and
reliability of electronic products delivered to the Government. ESS is interrelated with the requirements set
forth in MIL-Q-9858, MIL-STD-785,
MIL-STD-781,
and MIL-HDBK-781. Quality Control is a manufacturing function
and Reliability Engineering is a design function. Although the Quality and Reliability disciplines
are related, in practice, they are conducted as separate programs without
common objectives. The Handbook uses the
ESS program as a means for integrating Quality Control and Reliability
Engineering tasks so as to assure achievement of reliability objectives during
manufacture. Supporting software is
available from Rome Laboratory that fully automates the details manual
procedures contained herein.
MIL-HDBK-454 General
Guidelines For Electronic Equipment, November
2000. 194 Pages.
This
handbook is the technical baseline for the design and construction of
electronic equipment for the Department of Defense. It captures in one document, under suitable
subject heading, fundamental design guidelines for multiple general electronic
specifications. The opportunity to focus
on a single document, afforded to contractors, results in substantial savings
to the Government.
This
handbook provides guidance and lessons learned in the selection of
documentation for the design of electronic equipment. This hand book is for guidance only. The handbook cannot be cited as a
requirement. If it is, the contractor
does not have to comply.
MIL-HDBK-470A Designing
And Developing Maintainable Products And Systems,
Volume 1 & Volume 2, August 1997.
716 Pages.
This
handbook is approved for use by all Departments and Agencies of the Department
of Defense (DoD).
It was developed by the DoD with the
assistance of the military departments, federal agencies, and industry and
replaces in their entirety Military Handbooks 470 and 471 (both formerly
military standards). The handbook
provides guidance to maintainability managers and engineers in developing and
implementing a sound maintainability program for all types of products.
This
handbook is for guidance only. This
handbook cannot be cited as a requirement.
If it is, the contractor does not have to comply.
Maintainability
is a discipline that has become more important over the past 30 years as
military systems became more complex, support costs increased, and defense
budgets decreased. It is also important
in the commercial sector, where high levels of maintainability are increasingly
becoming an important factor in gaining customer loyalty. In fact, American products that once were
shunned in favor of foreign alternatives recently have made or are making a
comeback. This shift in consumer
preferences has been directly attributed to significant improvements in the
quality of the American products, a quality that includes good maintainability.
MIL-HDBK-472 Maintainability Prediction, May 1966. 176 Pages.
The
purpose of the Maintainability Prediction Handbook is to familiarize project
managers and design engineers with current maintainability prediction
procedures. To achieve this objective,
particular care has been exercised in selecting and including only those
procedures which are currently used in predicting the maintainability of
equipment and systems. The highlights of
each maintainability prediction procedure are presented in a clear, lucid and
intelligible manner and include useful supplementary information applicable to
specific procedures.
The
prediction of the expected number of hours that a system or device will be in
an inoperative or “down state” while it is undergoing maintenance is of vital
importance to the user because of the adverse effect that excessive downtime
has on mission success. Therefore, one
the operational requirements of a system are fixed, it is imperative that a
technique be utilized to predict its maintainability in quantitative terms as
early as possible during the design phase.
This prediction should be updated continuously as the design progresses
to assure a high probability of compliance with specified requirements.
A
significant advantage of using a maintainability prediction procedure is that
it highlights for the designer, those areas of poor maintainability which
justify product improvement, modification, or a change of design. Another useful feature of maintainability
prediction is that it permits the user to make an early assessment of whether
the predicted downtime, the quality, quantity of personnel, tools and test
equipment are adequate and consistent with the needs of system operational
requirements.
MIL-HDBK-502 Acquisition
Logistics, May 1997. 139 Pages.
The
Department of Defense is focusing on total cost of ownership throughout the
life cycle. Achieving affordable support
depends upon effective acquisition logistics management and planning.
This
handbook offers guidance on acquisition logistics as an integral part of the
systems engineering process. The
information contained herein is applicable, in part or in whole, to all types
of materiel and automated information systems and all acquisition strategies. However, this handbook does not present a
“cookbook” approach to acquisition logistics—such an approach would not
accommodate the vast, widely varying array of potential materiel
acquisitions. It does offer examples and
points to consider to help you shape your overall thought process. It addresses:
·
How systems engineering fits into the
acquisition process
·
Supportability analyses as part of the
systems engineering process
·
How to develop supportability requirements
·
The acquisition and generation of support
data
·
Logistics considerations for contracts.
·
The logisticians role on integrated product
teams.
MIL-HDBK-512 Parts Management, October
2000. 13 Pages.
This handbook
provides guidance for implementing an effective Parts Management Program (PMP)
on Department of Defense (DoD), industry and
commercial acquisitions. The guidance in
this document supports acquisition strategies and systems engineering practices
of DoD 5000.2-R.
This document provides performance-based parts management process
guidance which is intended to e adapted to individual program needs and which
provides appropriate latitude for innovative approaches and design solutions by
the contractors. The objectives of a PMP
are to reduce total cost of ownership and increase logistics readiness, and are
achieved through:
·
Promoting interoperability.
·
Enhancing the interchangeability,
reliability, and availability of parts
·
Minimizing diminishing source impacts and
parts obsolescence.
·
Assisting in meeting end item performance.
·
Assisting with parts selection and
qualification procedures.
·
Becoming compatible with the business
environment and trends.
·
Minimizing the proliferation of parts and
drawings through standardization.
MIL-HDBK-764 System
Safety Engineering Design Guide For Army Materiel,
January 1990, 346 Pages.
Most
all of the disciplines involved in the design, engineering, production, and
deployment of Army systems are concerned in some way with system safety. Accordingly, one of the primary functions of
the system safety engineer is to integrate the safety-related planning done by
various other disciplines. These other
disciplines are responsible for specific categories of safety planning, but
their primary responsibilities are for other services. For example, reliability engineers are
concerned with the failure rates of all components in a piece of equipment,
whether or not such failures are safety related.
System
safety engineers have found that accidents are caused by adverse environmental
effects and by errors in design, production, operations, maintenance, and
disposal. Thus each technical discipline
or management activity that can contribute to the elimination or minimization
of these accident causes should be integrated into the system safety
activities. Some of the principal
technical activities that can affect the safety of a system are:
·
Human Factors Engineering
·
Reliability Engineering
·
Maintainability Engineering
·
Maintenance Engineering
·
Test Engineering
·
Quality Engineering And Control
·
Industrial Hygiene
·
Training
·
System Safety Engineering And Management
Activities
·
Contracting
·
Budgeting

MIL-HDBK-781A Reliability
Test Methods, Plans, and Environments for Engineering Development,
Qualification, and Production, April 1996.
411 Pages.
This
handbook contains test methods, test plans, and environmental profile data
presented in a manner which facilitates their use with tailorable
tasks when appropriate.
The
testing of equipment procured for new military systems is an increasingly
complex process. Test methods, test plans,
and test environments must be selected which will ensure that contractually
required reliability levels are attained in the field and early defect failures
are removed prior to field deployment.
MIL-HDBK-781 provides a menu of test plans, test methods, and
environmental profiles. The most
appropriate material may be selected for each program and incorporated into the
tailored reliability test program.
The
handbook sections on reliability test methods and test plans present methods
for growth monitoring, environmental stress screening,
mean-time-between-failure assurance testing, sequential tests, fixed-duration
tests, and all-equipment tests, including a durability/economic Life Test. The sections on test environmental profiles
provide typical test environments for fixed-ground equipment, mobile ground
vehicle, shipboard, jet aircraft, turboprop and helicopter, and missiles and
assembled external stores equipment. The
references provided will expand the user’s knowledge and aid in the design and
implementation of reliability test programs through more details data.
MIL-HDBK-1798
(Superseding MIL-STD-1798) Mechanical
Equipment and Subsystems Integrity Program, December 1997, 34 Pages.
This
standard sets forth programmatic tasks for the development, acquisition
maintenance, modification, and operation of mechanical equipment and mechanical
elements of airborne, support and training subsystems to assure operation
soundness, dependability and affordability throughout the life cycle of Air
Force Systems. The Mechanical Equipment
and Subsystems Integrity Program, MECSIP, consists of a series of disciplined
time phased actions, procedures, analyses, tests, etc., which when developed
and applied in accordance with this standard will ensure more reliable,
affordable, and supportable equipment and subsystems, thus contributing to the
enhancement of total systems mission effectiveness and operational suitability.
MIL-HDBK-1823 Nondestructive Evaluation System Reliability Assessment, April
1999. 112 Pages.
This
handbook provides uniform guidance requirements for establishing NDE procedures
used to inspect new or in-service hardware for which a measure of NDE
reliability is required. They are,
specifically, Eddy Current (EC), Fluorescent Penetrant
(PT), Ultrasonic (UT), and Magnetic Particle (MT) Testing. This document may be used for other NDE
procedures if they are similar in output to those listed herein, such as
Radiographic testing, Holographic testing, Shearographic
testing, etc.
NDE
systems are classified into either of two categories: those which produce only
qualitative information as to the presence or absence of a flaw, i.e., hit/miss
data, and systems which also provide some quantitative measure of the size of
the indicated flaw, i.e., â vs. a data .
MIL-HDBK-2084 Handbook
For Maintainability Of Avionic And Electronic Systems And
Equipment, July 1995, 34 pages.
This
document was originally MIL-STD-2084 before designation as a handbook.
Maintainability
is an attribute of design and is a measure of the ease, rapidity, and accuracy
with which systems or equipment can be restored to operation status following
failure or repair. A high degree of
readiness and availability of avionic and electronic systems and equipment can
be assured only when their design allows for positive and accurate identification
of operational status, and when items are found defective, rapid and efficient
fault isolation, removal, replacement, and subsequent repair.
The
special features designed and built into systems which make them easy to
maintain and efficient to support result when maintainability is clearly
defined as a system requirement and the maintainability program is established
as a functional area of design. The
purpose of this standard [handbook] is not to subrogate the maintainability
program requirements of MIL-STD-470,
but merely to amplify the design criteria requirements of the maintainability
program and to emphasize maintainability by design.
Under
the concept of maintainability by design, emphasis is placed on those design
areas which tend to have the greatest influence on ease of maintenance. This includes requirements for
modularization, replacement at higher levels, and increased depth of
localization. These physical and technical
considerations of maintainability design are necessary if complex avionic and
electronic systems and equipment are to be supported efficiently at all levels
of maintenance.
MIL-HDBK-2164A Environmental
Stress Screening Process, June 1996.

This handbook provides guidelines for Environmental Stress Screening (ESS) of electronic equipment, including environmental screening conditions, durations of exposure, procedures, equipment operation, actions taken upon detection of defects, and screening documentation. These guidelines provide for a uniform ESS process that may be utilized for effectively disclosing manufacturing defects in electronic equipment caused by poor workmanship and faulty or marginal parts. It will also identify design problems if the design is inherently fragile or if qualification and reliability growth tests were too benign or not accomplished. The most common stimuli used in ESS are temperature cycling and random vibration. A viable ESS program must be dynamic; th
