Lhe assembly shall be classed defective if separation of assembly or any visible movement of the electrodes in the eyelet is observed. If one or more defectives occur

42、 the lot shall be rejected. (Test samples shall not be returned to the lot). 4.5.6 Insulation Test.-The required D.C. voltage (315 + 10 volts) shall be applied between the shorted electrodes and the cup of all detonators. The resistance shall be a minimum of 22 megohms when measured between the elec

43、trodes and the cup. If any detonator fails to meet the requirements, it shall be classed defective. All defectives shall be removed from the lot. 4.5.7 Resistance of Shorting Clip.-The resistance of the detonator with shorting clip shall be measured between electrodes. The shorting clip shall then b

The resistance should be measured with a current limited to one milliampere. 4.5.8 Functioning.-The detonator assemblies shall be tem- perature conditioned at 70 t 10 OP for two (2) hours minimum prior to performing the functioning tests. The tests shall be performed as speci

46、fied in MIL-STD-331, Test 301.1 except that the witness plate be 1/8 inch minimum and optionally round, 1.22 - .O1 dia. Witness plate hardness shall be Rockwell B7O to B95. The base of the detonatorshall be placed directly against the center of the witness plate and electrical contact made through a
