MIL-PRF-22885H
Temperature conditions during electrical endurance load cycling are as specified in table XV. Altitude
j.
electrical tests shall be conducted at room temperature conditions only. Switches which are tested to
resistive, inductive, and lamp loads shall be subjected to the minimum number of operating cycles at
maximum temperature as specified (see 3.1). Switches which are tested to motor loads shall be subjected
to the minimum number of operating cycles at room ambient conditions.
k.
The dc power source shall provide the rated or inrush current on resistive loads within 300 µs after closing
the circuit with a bounceless contact device. Oscillograms shall be provided with the test report
documenting this characteristic.
l.
Electrical tolerances are as follows:
Voltage: ±5 percent for dc, ±7 percent for ac.
Frequency: ±5 percent.
Current: ±5 percent.
