A sequence of actions, the correct performance of which will result in a valid test of an item’s response to a particular forcing function or combination of functions. Within each teet method there are one or more test procedures. 4. GENERAL REQUIREMENTS 4.1 General. This standard describes a series of engineering tasks and supporting documentation to assure the.tailoring of environmental test conditions to individual equipment applications. An environmental engineering specialist should be utilized to effectively apply this standard. b 4.2 Iailoring 4.2.1” f)biective of tailorin~.
The objective of tailoring, as applied in this standard, is to assure that military equipment is designed and tested for resistance to the environmental stresses it will encounter during its life cycle. Figure 1 illustrates the environmental tailoring process. Figure 2 shows generalized environmentallife cycle histories that may be used in developing a life cycle profile. 4.2.2 ~ine tasks. It is necessary to give proper consideration to environments throughout the development process in order to obtain a quality product. To assure such consideration, environmental management plans shall be formulated that require the following engineering tasks: determination of life.
cycle environmental conditions; establishment of environmental design and test requirements, including a test plan; and collection and analysis of field data for verification of environmental design and test criteria. Proper attention to each of these tasks insures that the correct environments are identified for teat, that engineering development as well as qualification tests are phased properly into the item’s acquisition program, that environmental teat conditions are traceable to life cycle conditions realistically y encountered, and that testing is appropriate for the item application. The following plans, tasks, and documentation are established to facilitate the tailoring process.
Each shall be prepared directly by the procuring activity or by the contractor as directed by the procuring activity. 4.2.2.1 Environmental Man&ze ent Plaq. The overall purpose of this plan is to develop a viable and cost effective progrsm to assure that military equipment will be designed and tested for all pertinent environmental conditions to which it will .besubjected during its life cycle.
The overall management of the environmental program shall include consideration of manpower requirements, scheduling, life-cycle environmental conditions, test tailoring, test performance, analysis of results, corrective actions, and collection of data 0 about, and analysis of, actual field environments. Plans for monitoring,. assessing, reporting and implementing the entire environmental program shall be addressed. The environmental management plan shall be documented according to DID DI-R-7123. 4.2.2.2 UC%. 1 ir t A life cycle history of events and associated environmental conditions for an item from its release from manufac- turing to its retirement from use shall be determined.
The life cycle shall include the various phases an item will encounter in its life, such aa: handling, shipping or storage prior to use; phases between missions, such as stand-by or storage or transfer to and from repair sites; geographical
