MIL-DTL-83503C
4.6.5 Withstanding voltage (see 3.5.3).
4.6.5.1 Sea level. The mated connectors shall be tested in accordance with test procedure EIA-364-20
test condition I. The following details shall apply:
a. Points of application: The test voltage shall be applied between two adjacent contacts and
between the housing and the contacts nearest the housing, if the housing is conductive see 3.1.
b. Duration of test voltage: 5 seconds, minimum.
4.6.5.2 At altitude. The connectors shall be tested in accordance with test procedure, EIA-364-20 test
condition IV. The following details shall apply:
a. Special preparations or conditions: Mated connectors shall be placed in a vacuum chamber at a
pressure of 33.0 millimeters of mercury (70,000 feet), maximum.
b. Magnitude of test voltage: A test voltage shall be applied for one minute during the first five
minutes at altitude and for one minute during the following thirty minutes while at altitude and after
30 minutes at altitude (see 3.1).
4.6.6 Cable retention (flat cable only) (see 3.5.4). The unmated wired connector with strain relief, when
applicable, shall be mounted by normal mounting means and aligned with the test fixture. The following
details shall apply:
a. An axial force of 8 ounces (2.22 Newton's) per contact shall be applied.
b. The force shall be applied 6 inches (152.4 mm) from the mating face of the connector to the cable
and shall be pulled away from the connector in a direction that will put the maximum stress on the
contact-cable interface.
4.6.7 Vibration (see 3.5.5). Mated connectors shall be tested in accordance with test procedure
EIA-364-28, test condition IV. The following details shall apply:
a.
Preparation: All contacts shall be wired in series.
b.
Applied current: 10 milliamperes.
Fixture: See figure 1.
c.
d.
The cable shall be supported at a distance of 4 inches from the connector body.
4.6.8 Low level contact resistance (see 3.5.6). Connectors shall be tested in accordance with test
procedure EIA-364-23. The following details shall apply.
a. Test samples shall consist of mated connector pairs. Unless otherwise specified, twenty percent,
but not less than 9 contacts shall be tested. Contact test positions shall be evenly distributed in
each row of multi-row connectors, at each end, and in the middle.
b. Wire size when applicable shall be as specified in the detail specification sheets (see 3.1).
c. Environmental conditioning not required.
d. When connectors are assembled to printed wiring boards, the voltage drop shall be taken at the
terminations at the point of attachment to the board.
