MIL-DTL-3885G
3.7.3 Dielectric withstanding voltage. There shall be no evidence of voltage breakdown
when tested as specified in 4.4.3.
3.7.4 Contact resistance variation (applicable only to assemblies using tinsel conductors).
The contact resistance variation of each terminal and the tinsel conductor shall not exceed 0.06
ohm when tested as specified in 4.4.4.
3.8 Mechanical requirements.
3.8.1 Interchangeability. Connectors shall be tested as specified in 4.5.1. Like units,
assemblies, and subassemblies shall be physically and functionally interchangeable, without
modification. Individual items shall not be handpicked for fit.
3.8.2 Soldering. MIL-HDBK-454, requirement 5, provides guidance on soldering of
electrical connections. All soldered electrical connections shall be tested in accordance with
3.8.3 Pull. After being subjected to the test specified in paragraph 4.5.3, the cable
assembly shall show no straining of individual conductors (when visible without major
The pull shall be applied gradually to the required force and held at that force for 30 seconds.
3.8.4 Pull on connector components. Terminals and taper pins shall not pull off of the
conductor ends or out of connectors when subjected to the test specified in 4.5.4.
3.8.5 Immersion (cable assemblies with watertight connectors and splices covered with
molded rubber or shrinkable tubing). Cable assemblies shall be subjected to the test specified in
4.5.5. There shall be no evidence of moisture penetration into the connector, splice, or molded
sections. The tested cable assemblies shall meet the requirements of insulation resistance
(see 3.7.2).
3.8.6 Durability. Connectors that must be assembled to given dimensions, and that must
be potted or molded in accordance with the information contained on the cable assembly drawing,
shall be subjected to the durability test specified in 4.5.6. Following the test, and while still
mated, the connectors shall meet the electrical requirements of 3.7. In addition, there shall be no
physical damage, and the force required to unmate the connectors shall be within 10 percent of
that measured prior to performing the durability test (see 6.6).
3.9 Service conditions.
3.9.1 Grind test (cables assemblies with molded or potted components only). After
grinding as specified in 4.6.1, molded and potted components of the cable assembly shall show no
voids or pits when viewed with 3X magnification.
3.9.2 Low-temperature flexibility (cable assemblies with added transition). Each portion
of a cable assembly containing a splice, crotch, or cable to jacket transition, shall be tested as
specified in 4.6.2. Upon examination after test, there shall be no visible cracks, separation of the
