MIL-DTL-83517A
4.5.6.2 Pressurized and weatherproof connectors (see 3.9.2). The unmated connector shall be
mounted in its normal manner in the specific mounting hole (see 3.1) on a closed container. The
specified air pressure (see 3.1) shall be applied to the interior of the container. The exposed portion of
the connector under pressure shall be fully immersed in water or alcohol-water mixture and observed for
1 minute minimum.
364-21, measured between the center contact and body.
4.5.8 Center contact retention (see 3.11).
contact of an unmated connector. This force shall be applied without shock until the specified force has
been reached. The force shall be applied for a minimum period of 5 seconds. After removal of specified
force the actual locations of the center contact shall be determined on recessed socket contacts, the tool
specified in the appendix will be used (see figure A-11).
4.5.8.2 Torque (see 3.1 and 3.11.2). The torque specified shall be applied to the center contact of an
unmated connector for a minimum period of 10 seconds on recessed socket contacts, and the tool
specified in the appendix will be used (see figure A-11).
4.5.9 Dielectric withstanding voltage (see 3.12). Connectors shall be tested in accordance with
condition 1 of procedure EIA 364-20. The following details shall apply:
a. Special preparation or conditions.
(1) The maximum relative humidity shall be 50 percent. When facilities are not
available at this test condition, connectors shall be tested at room ambient
relative humidity. In case of dispute, if the test has been performed at room
ambient relative humidity, retesting shall be performed at 50 percent maximum
relative humidity.
(2) The center contact of plug connectors and receptacle connectors shall be
positioned in such a manner as to simulate actual assembly conditions.
(3) Precautions shall be taken to prevent air-gap voltage breakdowns.
(4) The voltage shall be metered on the high side of the transformer.
b. Magnitude of test voltage (see 3.1). The voltage shall be instantaneously applied.
c. Nature of potential Alternating current.
d. Points of application of test voltage Between the center contact and body.
364-26. The following details and exceptions shall apply:
a. Test condition - B.
b. Salt solution 5 percent.
After exposure, connectors shall be washed, shaken, and lightly brushed as specified in procedure EIA
364-26 and then permitted to dry for 24 hours at 40ºC. Connectors shall then be inspected for evidence
of corrosion, pitting, and ease of coupling.
