MIL-DTL-28804D
4.7.12 Humidity (see 3.6.11). Fully wired connectors shall be subjected to a humidity test in accordance with method 1002 of
MIL-STD-1344, type II, the following exceptions and details shall apply:
a. Omit step 7.
b. Upon completion of step 6 of the final cycle, connectors shall be removed from the chamber and surface moisture
removed from the insulators.
c. Immediately following removal of surface moisture, dielectric withstanding voltage (see 4.7.7) and insulation resistance
(see 4.7.8) shall be measured.
d. After the 24-hour conditioning period, the insulation resistance (see 4.7.8) shall be measured again.
4.7.13 Vibration (see 3.6.12). Mated connectors shall be tested in accordance with method 2005 of MIL-STD-1344, test
condition IV. All contacts shall be wired in series. For size 26 wire, a strain relief clamp may be mounted directly on the connector.
4.7.14 Shock (specified pulse) (see 3.6.13). Mated connectors shall be subjected to method 2004 of MIL-STD-1344, test
condition G. One shock shall be applied in each direction of the three major axes of the connectors. Receptacles shall be
mounted similar to the mounting of 4.7.13. Plugs shall be engaged with the receptacles and shall not be held by any locking
means. All contacts shall be wired in series with a minimum of 100 milliamperes of current allowed to flow and the wire bundles or
cables shall be clamped to structures that move with the connectors. A minimum of 8 inches of wire or cable shall be unsupported
behind the rear of the receptacle and 4 1/2 inches (114.30 mm) of wire or cable shall be unsupported behind the rear of the plug. A
suitable instrument shall be used to indicate any discontinuity or interruption of current flow.
4.7.15 Durability (see 3.6.14). Connectors shall be tested in accordance with method 2016 of MIL-STD-1344. the following
details shall apply:
a. Counterpart connectors shall be mated and unmated 500 times at a rate of 200 100 cycles per hour in a manner to
simulate actual service.
b. After 500 cycles, the mated connectors shall be subjected to salt spray (see 4.7.16).
4.7.16 Salt spray (corrosion) (see 3.6.15). Mated connectors shall be subjected to salt spray in accordance with method 1001 or
MIL-STD-1344, the following details shall apply:
a. Test condition B.
b. Measuring after test: Contact resistance (see 4.7.9) and mating and unmating force (see 4.7.5) shall be measured.
4.7.17 Oversize pin exclusion (see 3.6.16). A hardened steel oversize pin, as specified in 3.6.16, shall be placed in a position
centered and parallel to the axis of the socket contact. A 12 ounce (3.34 N) axial force shall then be applied tending to force the
test pin into the socket contact. After completion of the test, contact resistance (see 4.7.9) shall be measured on 20 percent or a
minimum number of four socket contacts in each connector.
4.7.18 Probe damage (see 3.6.17). Socket contacts shall be tested in accordance with method 2006 of MIL-STD-1344, the
following details shall apply:
a. Number and size of samples: 20 percent of the contacts or a minimum of four contacts.
b. Probe damage tool shall be inserted into the contact to a depth of .160 .020 inch (4.06
0.51 mm).
c. The diameter of the handle .190 inch (4.82 mm) is not applicable.
d. The tolerance on the inch-pounds shall be 10 percent in lieu of the values specified in MIL-STD-1344.
e. After testing, contact engagement and separation force shall be measured (see 3.6.9).
