Barometric pressure (reduced): Method 105 of MIL-STD-202, condition D (100,000 feet). 125 percent of dc rated
voltage applied. See MIL-PRF-83421 for voltage limitations.
Vibration, random (optional): In accordance with MIL-PRF-83421 when ordered with the "-" replaced with "H" in
the PIN.
Immersion: Method 104 of MI L-STD-202, test condition C.
DWV:
Insulating sleeves: Greater than 4,000 volts, dc.
Terminal to terminal: 200 percent of dc rated voltage.
Terminals to case: 200 percent of dc rated voltage.
IR:
Insulat i ng sleeves: 10,000 megohm s, minimu m.
Terminal to terminal: Not less than 50 percent of initial requirement.
Terminals to case: 5,000 megohms, minimum.
∆C:
Styles CRH01 through CRH05: Maximum of ±0.25 per c ent.
Styles CRH06 through CRH00: Maximum of ±1.0 percent.
DF: 0.15 percent.
Moisture resistance: Method 106 of MIL-STD-202.
DW V, IR, ∆C, 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: 2 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 IV.
