MIL-DTL-3885G
4.3.4.4 Disposition of samples. Sample units that have been subjected to group C
inspection shall not be delivered on contract or order, except those units that have undergone tests
as indicated by an asterisk (*) in tables IX and X. These units may be delivered on contract or
order provided they have been reconditioned and are subjected to, and meet the requirements of,
group A inspection.
4.4 Electrical tests.
4.4.1 Continuity. Each circuit of each assembly shall be tested for continuity and correct
connections between its terminations, using a potential of not more than 10 volts. A suitable
indicator or automatic continuity tester may be used. The cable assemblies shall meet the
requirements of 3.7.1.
4.4.2 Insulation resistance. Insulation resistance shall be measured in accordance with
method 302 of MIL-STD-202, test condition A. The insulation resistance shall be measured
between each conductor and the remaining conductors connected together to shielding and metal
shell, when present. The cable assemblies shall meet the requirements of 3.7.2.
4.4.3 Dielectric withstanding voltage. Dielectric withstanding voltage testing shall be
performed in accordance with method 301 of MIL-STD-202. A potential of 1000 ±10 volts direct
current shall be applied for one minute when performed manually. The potential shall be applied
between each conductor and the remaining conductors connected together to shielding and metal
shell, when present. The cable assemblies shall meet the requirements of 3.7.3. This test shall be
performed only once on units to be furnished on contract. This test may be performed during
final inspection.
4.4.4 Contact resistance variation (assemblies using tinsel conductors only). Each
terminal shall be clamped so that it cannot move and the conductor shall be bent at the point of
attachment to the terminal so that it is moved 90 degrees to each side of the axial position for a
total excursion of 180 degrees. The stressing shall be done in two mutually perpendicular planes.
The resistance variation shall be measured with a bridge or by the use of an electronic voltmeter
to measure the voltage variation, with a current of 0.30 to 0.50 ampere flowing through the
conductors and mated connectors. Contact resistance variation shall meet the requirements of
4.5 Mechanical tests.
4.5.1 Interchangeability. Contact locations and interfacial dimensions of the connector as
specified in the applicable connector specification or drawing, shall be measured. Gages, when
specified in the drawing or contract (see 6.2), shall be used to determine conformance to the
physical and functional interchangeability requirements. Gaging may be performed prior to
assembly provided assembly of the connector components will not cause a dimensional change to
the connector. Acceptance shall be in accordance with the requirements of 3.8.1.
