u. Life Cycle Environmental Profile (LCEP). Design and test decision baseline document outlining real-world, platform-specific, environmental conditions that a specific materiel system or component will experience during service-related events (e.g., transportation, storage, operational deployment/use) from its release from manufacturing to the end of its useful life.
v. Life cycle profile. A time history of events and conditions associated with materiel from its release from manufacturing to its removal from service, including demilitarization. The life cycle should include the various phases materiel will encounter in its life, such as: packaging, handling, shipping, and storage prior to use; mission profiles while in use; phases between missions such as stand-by or storage, transfer to and from repair sites and alternate locations; and geographical locations of expected deployment.
w. Materiel. A commodity or set of commodities. A generic class of hardware designed to perform a specific function.
x. Materiel developer. An agency or group of individuals involved in designing, testing, or evaluating materiel to meet developer performance requirements.
y. Mission profile. That portion of the life cycle profile associated with a specific operational mission.
z. Operational worthiness. The capability of materiel, a subsystem, or component to perform its full array of intended functions.
aa. Parameter. Any quantity that represents a descriptive generalization of a certain characteristic physical property of a system that has a certain value at a particular time.
bb. Parameter level. The value of a physical property that documents the degree, extent, or level at which a parameter exists at a given location at a given point in time, or the value to which a variable test control is set (see test level).
cc. Platform. Any vehicle, surface, or medium that carries the materiel. For example, an aircraft is the carrying platform for installed avionics items or transported or externally mounted stores. The land is the platform for a ground radar set, for example, and a person for a man-portable radio.
dd. Platform environment. The environmental conditions materiel experiences as a result of being attached to or loaded onto a platform. The platform environment is influenced by forcing functions induced or modified by the platform and any platform environmental control systems.
ee. Program manager. The (Government) official who is in charge of the acquisition process for the materiel.
ff. Service life. Period of time from the release of materiel from the manufacturer through retirement and final disposition.
gg. Tailoring. The process of choosing design characteristics/tolerances and test environments, methods, procedures, sequences and conditions, and altering critical design and test values, conditions of failure, etc., to take into account the effects of the particular environmental forcing functions to which materiel normally would be subjected during its life cycle. The tailoring process also includes preparing or reviewing engineering task, planning, test, and evaluation documents to help ensure realistic weather, climate, and other physical environmental conditions are given proper consideration throughout the acquisition cycle.
hh. Test item. Specific materiel, a subsystem, or component being tested, including its container and packaging materials, that is representative of the materiel being developed. A representative sample of materiel that is used for test purposes.
ii. Test level. The value at which a test condition is set or recorded. (Also, see parameter level.)
jj. Test method. The criteria and procedures used to formulate an environmental test. Laboratory test methods are identified by the environment (or combinations of environments) in Part Two of this document.
kk. Test plan. A document that may include test procedures and test levels, failure criteria, test schedules, and operational and storage requirements.
