|
|
Environmental Specifications are derived from MIL-STD-883B and MIL-PRF-55310D and are generally performed on a sampling basis for qualification to insure that all units in production meet or exceed the required specifications. This sampling method, coupled with Workmanship Standards to Quality System certified to ISO-9001, insures a superior product.
