Downloaded from https://www.everyspec.com MIL-STD-81OD 19 July 1983 b. @2rtest interr~. Any interruption in a cyclic or steady-state test that results in more extreme exposure of the test item than required by the equipment specifications should be followed by a complete physical o inspection and an operational check (where possible) before continuation of testing. This is especially true where a safety problem could exist, such as with munitions. If a problem is discovered, the preferable course of action is to terminate the test and reinitiate testing with a new test item.
If this ie not done and a test item failure occurs during the remainder of the test, the test results could be considered invalid because of the overtest conditions. If no problem has been encountered, reestablish pre-interruption conditions and continue from the point where the test tolerances were exceeded. , 11-2 ~ II-2.1 ~. Before starting the test, determine from the test plan: a. Which test procedures are required~ b. The high-temperature operation and storage accompanying temperature cycles and durations. requirements and c. If relative humidity is to be controlled. d. The location of temperature sensors.

The test item’s test configuration. standard ambient checkout to provide baseline data. Conduct the checkout as followe: Step 1. Install temperature sensors in, on, or around the test item as required by the test plan. Step 2. Insert the test item into the chamber and stabilize the test item at controlled ambient conditions (General Requirements; 4.4b). Step 3. Conduct a complete visual examination of the test item with special attention to stress areas, such as corners of molded casee. Step 4. Document the results. Step 5. Prepare the test item in accordance with General Requirements, -. 4.5.2, and required test item configuration. Step 6.
Conduct an operational checkout in accordance with the approved test plan. . Step 7. Record the results for compliance with General “Requirements, 4.5.1.1. Step 8. If the test item operates satisfactorily, proceed to II-3. If not, resolve the problems and restart at Step 1 above. o METHOD 501.2 19 July 1983 501.2-14 .-,
