MIL-STD-1344. The following details and exceptions shall apply:
the test specified in method 1011 of MIL-STD-1344. The following details apply:
service to a rigid panel. The torque wrench shall be attached as shown on figure 23. After mating the plug
and receptacle connectors, a torque shall be applied to the accessory end of the plug at a rate of
approximately 10 pounds-inches per second until the required torque is achieved. The applied load shall
be held for 1 minute, then the load shall be released. The test shall then be repeated on the accessory end
of the receptacle.
