This specification is intended to define design requirements and test procedures (1) to be followed in subjecting Aerospace Ground Equipment (AGE) for space systems to simulated and accelerated environmental conditions that will insure satisfactory operating and (2) to be followed in reducing deterioration when AGE is operated and/or stored at manufacturing facilities, test facilities, and launch ranges. This specification establishes environmental criteria for designing Aerospace Ground Equipment (AGE) in support of space systems. The test levels in this specification have been elevated to compensate for absence of combined environments during test, and to allow for variations in equipment and operating conditions. Environmental requirements are summarized in Table 1.
