Effort was made to determine whether combinations of natural and induced environmental conditions would produce debilitating or desirable effects different from those resulting from singly applied environmental tests. The program consisted of five phases 1 an evaluation and analysis of standard single-environment test procedures applicable to a selected item of Air Force electronic equipment, 2 the performance of burn-in and base-line-reference tests, i.e., tests to determine performance data for comparison purposes, 3 the performance of natural and induced single-environment tests beyond design level to determine damage threshold, 4 the development of a test program consisting of tests which simulate combinations of those environments applicable to the selected test item, and 5 test trials to determine the effect of the combined-environment tests as compared to the effect of the single-environment tests. Data are limited to the specific item tested and to the time periods utilized in the test procedure however, some observations on the design of combined-environment tests and desirable characteristics in a test item are also included.
