22、h test. Dielectric strength shall be evaluated by applying 500 VDC or VAC for 60 $ seconds in accordance with the requirements of MIL-STD-202, Method 301. Each cartridge shall meet the requirements of 3.3.6. 43.7 Power current test. Power current shall be evaluated by conditioning the cartridge at +
23、200 f 5F for 4 hours minimum and then applying a direct current of not less than 1 ampere supplying a minimum of 1 watt from terminal stud to case for a period of S-izminutes. The test current shall be regulated to within 2 percent. Each cartridge shall meet the requirement of 3.4.1. 43.8 Static dis
24、charge.
