MIL-DTL-83503C
4.6.9 Salt spray (corrosion) (unmated) (see 3.5.7). Connectors shall be tested in accordance with
test procedure EIA-364-26, condition B. The following details shall apply.
a. Connectors shall then be examined as specified in test procedure EIA-364-26 for evidence of
corrosion.
b. Measurements after test: Withstanding voltage and low level contact resistance shall be
4.6.10 Contact retention (removable contacts only) (see 3.5.8). Connectors shall be tested in
accordance with test procedure EIA-364-29. The following details shall apply:
a. Axial direction: Shall be applied in both directions.
b. Axial load: As specified in the detail specification sheets (see 3.1).
4.6.11 Connector-cable flexing (flat cable only) (see 3.5.9). Connectors shall be tested in accordance
with test procedure EIA-364-41, test condition II. The following details shall apply:
a. Test procedure:
(1) The assembled wired connector shall be installed in fixture.
(2) Each cable shall be gripped 12 inches (305 mm) from the connector with an applied tension of
2 ±1 pound per inch of cable width.
(3) Each cable shall be in individually loaded.
(4) The cable or the connector shall be moved through an arc of 140 degrees ±10 for 50 cycles.
(5) One complete cycle shall consist of the rotation of the cable or connector from the neutral
position to 70 degrees ±5 in both directions.
(6) The cycling rate shall be 10 ±1 cycles per minute.
(7) A monitoring current of 10 ma shall be applied through the conductor of the test cables and
the contacts of the connector in series.
b. Suitable equipment shall be used to monitor the current flow and indicate a 1 microsecond or
greater interruption of current flow.
c.
Measurements: A visual inspection shall be made to check for flaws or damage and the
withstanding voltage shall be measured as specified in 4.6.5.
4.6.12 Contact resistance (see 3.5.10). The requirements specified in 3.5.10 shall be met when tested
in accordance with test procedure EIA-364-06. Wire length shall be 6 inches (15.24 cm). Twenty percent,
but not less than 9 mated connector pairs shall be tested. The applicable test circuit shall be as shown on
a.
Wire size: As specified (see 3.1).
b.
Preparation: Connectors mated.
c.
Test current: 1 ampere.
d.
When connectors are assembled to PWB, the voltage drop shall be taken at the point of
attachment to the boards.
e. Contact resistance shall be a specified in the specification sheets (see 3.1).
