MIL-PRF-83421/2D
IR:
Insulating sleeves: 10,000 megohms, minimum.
Terminal to terminal: Not less than 50 percent of initial requirement.
Terminal to case: 5,000 megohms, minimum.
Ć C: Maximum of ±0.25 percent.
DF: 0.15 percent.
Moisture resistance: Method 106 of MIL-STD-202.
DWV, IR, ĆC, and DF: Same as for immersion.
Low temperature life: In accordance with MIL-PRF-83421, except measurements shall be made at the following
temperatures:
t1 = +25°C: Record initial capacitance, dissipation factor, and insulation resistance.
t2 = - 65°C: 48 hours rated dc voltage applied.
t3 = Maximum operating temperature: Two hours rated dc voltage applied (allow for derating).
t4 = +25°C: Record capacitance, dissipation factor, and insulation resistance. Limits of change shall be as
specified in table III.
