MIL-DTL-27434B
4.4.3 Gage test for contacts. Contacts shall be gaged or measured to determine compliance with
3.3.1.1.
4.4.4 Dielectric withstanding voltage (see 3.4). Connector adapters 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, connector adapters 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 by use of a mating
connector or a jig simulating a mating connector.
3. The voltage shall be metered on the high side of the transformer to an accuracy of 5
percent.
4. Connector adapters having different voltage requirements at each end shall be
subjected to the lower voltage (see 3.1).
b. Magnitude of test voltage Unless otherwise specified (see 3.1), 1,500 volts root mean square,
instantaneously applied.
c. Nature of potential Alternating current.
d. Points of application of test voltage Between the center contact and the body.
e. Examination After the test, connector adapters shall be examined for evidence of breakdown.
4.4.5 Salt spray (corrosion) (see 3.5). Connector adapters shall be tested in accordance with method
101, test condition B, of MIL-STD-202. At the conclusion of this test, the connector adapters shall be
washed, shaken, air blasted, and then permitted to dry for 24 hours at 40ºC. The connector adapters
shall then be examined for evidence of corrosion.
4.4.6 Vibration (see 3.6). Adapters properly mated with their mating connectors shall be tested in
accordance with method 204 of MIL-STD-202. The following details and exceptions shall apply:
a.
Mounting of specimens Adapters shall be mounted by normal mounting means.
b.
Electrical load conditions No load.
c.
Test condition letter B.
d.
Measurements During vibration each adapter shall be monitored to determine electrical
discontinuity.
4.4.7 Shock (see 3.7). Adapters properly mated with their mating connectors shall be tested in
accordance with method 202 of MIL-STD-202. The following details and exceptions shall apply:
a. Mounting method By normal mounting means.
b. Acceleration requirements 100 G's.
c. Number of blows Adapters shall be subjected to nine blows, three in each of three mutually
perpendicular planes.
d. Electrical load No load.
e. Measurements During shock each adapter shall be monitored to determine electrical
discontinuity.
