MIL-DTL-83538D
4.6.14.2 Procedure II. The contact retention shall be tested as specified in test procedure of
EIA-364-29. The following details and exceptions shall apply:
b. Axial direction: Same as 4.6.14.1d, except the direction shall tend to displace the contacts to the
front.
c. Only the contacts to be tested need be installed in the connector.
4.6.15 Altitude low temperature. Wired, mated, assembled connectors shall be subjected to the test
specified in test procedure EIA-364-105. The following details shall apply (see 3.19):
a. No wire ends or splices inside the chamber.
b. Dielectric withstanding voltage test to be performed after return to ambient conditions shall be in
accordance with 4.6.8.1.
c. Insulation resistance test to be performed at 30,480 meters (100,000 feet) at -65°C and shall be in
accordance with 4.6.7.1.
d. A suitable fixture shall apply the holding force specified in 3.4.7.2 to hold the connector pair
together.
4.6.16 Accessory thread strength. Applicable to launcher receptacle only, see 3.20. The launcher
receptacle shall be fitted into a device that will hold it in place. The torque wrench shall be applied to the
adapter thread of the launcher receptacle at a rate of approximately 5 Newton-meter per second
(3.7 pound feet per second) until the torque required is achieved (see figure 7). 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 launcher receptacle accessory adapter using the torque values from MIL-DTL-83538/9.
4.6.17 Vibration. Qualifications only, see 3.21. Wired and mated connectors shall be subjected to the
applicable test(s) specified. All contacts shall carry a test current of 100 milliamperes maximum and shall
be continuously monitored for discontinuities throughout the test. A detector capable of detecting any
discontinuities in excess of 1 microsecond shall be used. A suitable fixture shall apply a holding force not
to exceed 271 Newtons (61 pounds) to hold the connector pair together (see figure 14).
The vibration level shall be monitored and recorded for the duration of the testing. It shall be monitored
and recorded from at least two different points. One of the measuring sensor shall be installed at the base
of the vibration plate and the other very close to the store receptacle. The measuring point adjacent to the
store receptacle shall be used for vibration control.
The applied holding force of 271 Newtons (61pounds), initially set before the vibration test, shall be
monitored and recorded before and after the test only to assure compliance to the 61 lbs max
requirement.
In order that all the data can be captured the above parameters shall be measured at a suitable rate
throughout the testing. The sampling rate should be not less than 1 measurement per minute.
The test report shall advise the sampling rate used for each parameter, and the values obtained.
The wire bundle shall be clamped to fixed points at least 203.2 millimeters (8 inches) from the rear of
the connector.
