Corrosion Resistance
Class W withstands 500-hour salt spray.
Class R withstands 48-hour salt spray.

Environmental Seal
Wired, mated connectors with specified accessories
attached, shall meet the altitude-immersion test specified by
MIL-DTL-83723 Series III.

Fluid Resistance
Connectors resist specified immersions in MIL-PRF-7808
(lubricating oil), MIL-PRF-23699 (lubricating oil),
MIL-PRF-5606 (hydraulic fluid), M2-V Chevron oil,
Coolanol 25, MIL-DTL-83133 (turbine fuel JP-8),
MIL-DTL-5624 (turbine fuels JP-4 and JP-5), SAE-AMS1424
Type I (defrosting fluid), and other solvents and cleaning
agents.

Durability
Mated connectors withstand a minimum of 500 mating
cycles for bayonet coupling straight plug (M83723/75, 76);
250 mating cycles for bayonet coupling RFI plug
(M83723/77, 78); and 250 cycles for all threaded coupling
plugs (M83723/86, 87, 91, 92, 95, 96, 97, 98).

Shock and Vibration Requirements
Wired, mated connectors shall not be damaged, coupling
ring shall not loosen, and there shall be no interruption of
electrical continuity longer than one microsecond when
subjected to the following:

Shock
Mated connectors withstand a pulse of approximate half
sine wave of 300 G ± 15 percent magnitude with duration
of 3 ± 1 milliseconds applied in three axes.

Vibration
Mated connectors withstand the following vibration levels:

• Random vibration per MIL-STD-1344, method 2005, test
  condition VI, letter J.

Shielding Effectiveness
RFI attenuation at the specified frequency meets the
requirements of MIL-DTL-83723 Series III.

• RFI shielding effectiveness of mated connectors with
  RFI backshells is measured in a triaxial radio frequency
  leakage fixture.

Shell-to-Shell Conductivity (Except class A)

• With RFI spring fingers, the maximum potential drop
  shall not exceed 5 millivolts.
  
• Without spring fingers, the maximum potential drop
  shall not exceed 200 millivolts.
