14、edges and internal openings. The “significant characteristics locations“ specified on the engineering drawing. 3.4.3 Measurement Technique The movement at each measurement point shall be recorded in two directions: (1) in the x/y plane from the observers view, and (2) in the z-dimension direction in

15、to or out of the x/y plane from the observers view. The observers view shall remain consistent always viewing from the front side of the part. 3.4.4 Test Procedure Visually evaluate the part before and after the test. Measure the part and record data at all specified locations at room temperature be

16、fore 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 the part and measure any significant characteristic locations only, during the last half-hour of each cold and hot extreme temperature per

17、iod. Automated programmable test cycles based on the listed test conditions may be accepted by prior agreement with the affected Materials Engineering Activity. Ramp speed 1 to 5 C per minute.
