1. SCOPE.
1.1 Purpose.
b. This document supports the functions of three different groups of personnel involved in the materiel acquisition process. Each of these groups is critical to the goal of successfully incorporating environmental considerations into materiel design, test, and evaluation. Although each group has different tasks to perform, none of these tasks can be isolated from the others in a successful acquisition program. As shown on figure 1-2, this information is intended for the following:
(1) Materiel acquisition program managers among whose responsibilities is ensuring materiel will function as required in intended operational environments. (See paragraph 4.1 below.)
(2) Environmental engineering specialists (EES) who assist combat and materiel developers throughout the acquisition process to tailor their materiel designs and test designs to environmental stresses/constraints expected during the materiel's service life. (See paragraph 4.2 below.)
(3) Design, test, and evaluation community analysts, engineers, and facility operators who meet user needs by focusing on tailored designs and tests. (See paragraph 4.3 below, and Part Two of this standard.)
1.2 Application.
The tailoring process described in this standard (i.e., systematically
considering detrimental effects that various environmental factors may have
on a specific materiel system throughout its service
life) applies throughout the materiel acquisition
cycle to all materiel developed for military or commercial applications, including
nondevelopment item (NDI) procurements, procurements, or modifications of Allied
systems or equipment, and cooperative development opportunities with one or
more Allied nations to meet user and interoperability needs (DoDD 5000.1).
a. Part One lays out a disciplined, tailored approach for acquiring systems
that will withstand the stresses of climatic, shock
and vibration environments that they expect to see in their
service lives. The basic process for acquiring materiel that satisfies users'
needs from this environmental engineering viewpoint is at figure
1-1.
b. Part Two also is an integral part of the
environmental tailoring process. It contains tailoring
information, environmental
stress data, and laboratory test methods. The environmental
data contained in the methods may help, but should not be used exclusively,
to define environmental stresses that materiel will encounter throughout its
service life. This will help engineers to tailor analyses and tests to specific
materiel and its defined life cycle. It is not valid to call out all of the
methods in this standard in a blanket fashion for a materiel system; nor is
it valid, once a method is determined appropriate, to regard the environmental
stress data, test criteria,
and procedures in the method as unalterable.
c. Guidance and test methods of this standard are intended to:
(1) Define environmental stress sequences,
durations, and
levels of materiel
life cycles.
(2) Be used to develop analysis and test criteria tailored to the materiel
and its environmental life cycle.
(3) Evaluate materiel performance when exposed to a life cycle of environmental
stresses.
(4) Identify deficiencies, shortcomings, and defects in materiel design,
materials, manufacturing processes, packaging techniques, and maintenance
methods.
(5) Demonstrate compliance with contractual requirements.
