ring shall not loosen, and there shall be no interruption
electrical continuity longer than one microsecond when
subjected to the following:
Mated connectors withstand a pulse of approximate half
sine wave of 300 G ± 15 percent magnitude with
of 3 ± 1 milliseconds applied in three axes.
Mated connectors withstand the following
- Random vibration per MIL-STD-1344,
method 2005, test
condition VI, letter J.
RFI attenuation at the specified frequency meets the
requirements of MIL-DTL-83723 Series III.
- RFI shielding effectiveness of mated connectors
RFI backshells is measured in a triaxial radio frequency
(Except class A)
