1/ Testing shall be performed with relay installed in socket and bracket assembly MIL-DTL-12883/51
and secured in mounting track MIL-DTL-12883/49.
2/ Relay shall not be installed in socket and bracket assembly MIL-DTL-12883/51.
3/ Leakage current at sea level.
Transients (applicable 0 -003 only): The time delay relay shall comply with MIL-STD-461 (applies to X1 and X2 terminals only; A1, A2, and A3 shall be wired but unloaded) and the requirements defined in method CE106, CS101, CS114, RE103, and RS103, except that the field intensity of RS103 shall be in accordance with table IV herein. Voltage spikes (transients of 500 microseconds or less duration) generated by the time delay relay and conducted on lines X1, X2 of the relay shall not exceed 42 volts. Voltages generated by the time delay relays shall be monitored on the control/power leads (+X1, X2) with an oscilloscope having the ability to detect, measure, and display voltage spikes of 0.25 to 1,000 volts amplitude and 10 nanoseconds to 50 microseconds duration. The oscilloscope shall be capable of retaining the display. The qualification test report shall include photographs of all oscilloscope-displayed spike voltages. Switches used to control the time delay relays shall not be EMI-suppressed in any way. During susceptibility testing, the relay shall not change state nor have the timing interval affected in any way by the EMI signals. The timing interval shall be considered to include the instants of turn-on and
turn-off.
