MIL-C-38983A
4.5.7 Static discharge. Cartridges shall be tested and shall not fire when subjected to an electrostatic
discharge of 150,000 ergs from a 500 ± 5 percent picofarad capacitor. The cartridge shall be tested across
pairs of pins or leads in all combinations and between the shorted pins or leads (all pins or leads shorted to
each other) and the case of the cartridge or ignition element. Electrical leads shall be attached to the ignition
element body and the shorted contact pins. The cartridge shall perform acceptably when ballistically tested.
4.5.8 Stray voltage. Cartridges shall be subjected to 2000 pulses of direct current. Each pulse shall be
100 milliamperes. Duration of pulse shall be 300 ms at a rate of 2 pulses per second.
4.5.9 Vibration. Cartridge shall be subjected to vibration tests prescribed in MIL-STD-810, Method 514,
Procedure I, except that table IV of this document shall apply as the time schedule for resonance dwell and
sinusoidal cycle times and figure 1 of this document shall apply as the vibration test curve for the vibration
test. The sample shall be divided into three equal quantities with one quantity conditioned to -65· F, one at
room temperature, and one to +250· F. The conditioning time shall be a minimum of 1 hour longer than the
time necessary to bring the cartridge to the required temperature. Each quantity shall then be vibrated in
accordance with table IV at the temperature to which that quantity was conditioned.
