15、Visually evaluate the part before and after the test. Measure the part and record data at all specified locations at room temperature before and after cycling on the production support foundation or test fixture. Also, during para. 3.3.5 “Short Term Heat and Cold Cycle“ testing, visually evaluate th

16、e part and measure any significant characteristic locations only, during the last half-hour of each cold and hot extreme temperature period. Automated programmable test cycles based on the listed test conditions may be accepted by prior agreement with the affected Materials Engineering Activity. Ram
