35、oduction or networking permitted without license from IHS-,-,-I MIL-DTL-28964C determination per sample unit and results shall be reported as pass or fail. The sample unit shall be seven pair completely fabricated insignia of each type and class. The requirements are applicable to the individual uni

36、t. For the bending strength test, the sample unit shall be one item and all prongs, on that item will be tested. However, one defect will be scored regardless of how many prongs fail on the item. 4.4 Tests 4.4.1 Test for clutches. The clutch shall be removed and replaced ten times from the prong. An

37、 attempt shall then be made to remove the clutch by hand without first depressing the release wings, during which time the clutch and prong shall be inspected to determine compliance with 3.2.2. 4.4.2 Test for bending strength. The prongs shall be bent five times through a 90 angle, 45“ on each side

38、 of the prongs perpendicular position. Bending of the prongs shall be performed slowly, and each bending action shall take 10 seconds. 4.4.3 Direct micro-thickness test for comer plating. The copper plating thickness shall be determined in accordance with ASTM-E 498. The results shall be evaluated t

39、o determine compliance with 3.4.1. 4.4.4 Test for thickness. The test shall be performed in accordance with ASTM-D 638. The test shall be performed to determine compliance with 3.2.1.1. 4.4.5 Test for baked enamel. Draw a knife edge across the face side of the specimen making four parallel scores on

40、e-sixteenth inch apart. Repeat this process, drawing the knife edge this time perpendicular to the previously scored lines, making small blocks in the finish. The finish shall then be examined to determine compliance with 3.4.1. 4.4.6 Acetone test for baked enamel. The enameled surface shall be wipe

41、d five times with a piece of cotton saturated with acetone. The cotton shall be examined to determine compliance with 3.4.1. 4.4.7 Test for nail strength for integral Drongs. The insignia to be tested will be placed in a jig which allows no movement of the insignia and positions prongs on a 30 degre

42、e angle above the horizontal. A vertical 10 lb. load shall be applied to the top third position of each prong. No evidence of breaking or cracking shall occur in compliance with 3.2.2. 5. PACKAGING 5.1. Packaging. For acquisition purposes, the packaging requirements shall be specified in the contrac

43、t or order (see 6.2).
