MIL-DTL-3643B
4.4.2 Dielectric withstanding voltage (see 3.4). Connectors shall be tested in accordance with
method 301 of MIL-STD-202. The following details shall apply:
a. Special preparations 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 made at room ambient relative humidity, retest shall be made at
50 percent maximum relative humidity.
(2) The center contact of electrical plug connectors and electrical 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 - 5,000 volts root mean square, applied at approximately 500 volts per
second until the rated test voltage is reached.
c. Nature of potential - AC voltage.
d. Points of application of test voltage - Between the center contact and body.
4.4.3 Salt spray (corrosion). Connectors and associated fittings shall be tested in accordance with
method 101, test condition B, of MIL-STD-202. At the conclusion of this test, the connectors and
associated fittings shall be washed, shaken, and air blasted and then permitted to dry for 24 hours at
40°C. The connectors and associated fittings shall then be examined for evidence corrosion (see 3.5).
5 PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the
contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor
personnel, these personnel need to contact the responsible packaging activity to ascertain packaging
requirements. Packaging requirements are maintained by the Inventory Control Point's packaging
activities within the Military Service or Defense Agency, or within the military service's system commands.
Packaging data retrieval is available from the managing Military Department's or Defense Agency's
automated packaging files, CD-ROM products or by contacting the responsible packaging activity.
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is not
mandatory.)
6.1 Intended use. Connectors and associated fittings covered by this specification are intended for use
in radio frequency applications up to 10,000 megahertz. They are designed for use with medium-size,
radio frequency, coaxial cables. Their use is governed by temperature limitations of materials, and they
are not recommended for use in applications where temperatures exceed 125°C.
