MIL-DTL-3650B
4.4.3 Dielectric withstanding voltage (when applicable) (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) Precautions shall be taken to prevent air-gap voltage breakdowns.
(3) The voltage shall be metered on the high side of the transformer.
b. Magnitude of test voltage - Unless otherwise specified, (see 3.1.), 10,000 volts root mean square.
c. Nature of potential - AC voltage.
d. Points of application of test voltage - Between the center contact and the body with the connector
properly mated with its associated connector or a suitable mating jig.
e. Examination - After the test, connectors shall be examined for evidence of breakdown.
4.4.4 Salt spray (corrosion) (see 3.5). Connectors shall be tested in accordance with method 101, test
condition B, of MIL-STD-202. At the conclusion of this test, the connectors shall be washed, shaken, air
blasted, and then permitted to dry for 24 hours at 40°C. The connectors shall then be examined for
evidence of destructive corrosion and pitting. (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 covered by this specification are intended for use in radio frequency
applications up to 1,000 megahertz. They are designed for use with large-size, radio frequency, coaxial
cables. Their use is governed by temperature limitation of materials, and they are not recommended for
use in applications where temperatures exceed 125°C.
6.2 Acquisition requirements. Acquisition documents should specify the following:
a. Title, number, and date of this specification.
b. Issue of DoDISS to be cited in the solicitation, and if required, the specific issue of individual
documents referenced (see 2.2 and 2.3).
c. Packaging requirements (see 5.1).
d. The supplier will not substitute for a specified material or combination of fabricated parts (see 3.3)
unless he obtains approval from the Government. Evidence to substantiate his claim that such a
substitution is suitable and is to be submitted with his request. Similar notification and
substantiating evidence will be submitted at any later time if substitution becomes necessary or
desirable. At the discretion of the Government, test sample units may be required to prove the
suitability of the proposed substitute.
