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
