35、 the test fixture as specified on the applicable drawing. The specified weight shall be dropped from a height of nine (9) inches, maximum, onto the firing pin to function the primer. The height of the drop shall be measured from the top of the firing pin to the bottom of the weight ball. Any primer
36、that fails to comply with the requirements specified in 3.4.1 shall be classed defective. 4.5.4.2 Waterproofness. - Following acceptance of the first article sample, one hundred and twenty-five (125) primers shall be selected-from each lot for this test. If three (3) or more primers fail to comply w
37、ith the specified requirements, the lot shall be rejected. All primers selected for the water- proofness test shall be conditioned as specified in 3.4.2, then removed and, within two (2) hours, shall be subjected to the functioning test as specified in 4.5.4.1. 4.5.5 Composition of priming mixture.
