MIL-DTL-83503C
evidence of cracking, crazing, or other physical damage. Discoloration of insulation or sealing material
shall not constitute failure. The connectors shall be capable of being manually mated and unmated at
extreme low temperature.
3.5.12 Shock (specified pulse). When connectors are tested as specified in 4.6.14, there shall be no
evidence of loosening of parts, cracks or breaks and there shall be no loss of electrical continuity during
the test greater than 1 microsecond.
3.5.13 Humidity. When the mated connectors are tested as specified in 4.6.15, there shall be no
cracking or separation of the insulation. Following the test, the connectors shall meet the requirements of
insulation resistance, withstanding voltage (sea level), and contact retention in 3.5.2, 3.5.3, and 3.5.8
respectively.
3.5.14 Mating and unmating forces. When connectors are tested as specified in 4.6.16, the force
required to mate and unmated the connector pairs shall be 1.5 to 8 ounce-force times the number of
contacts per connector, unless otherwise specified (see 3.1).
3.5.15 Durability. When mated and wired connectors are tested as specified in 4.6.17, there shall be no
base metal exposure or damaged parts that will be detrimental to the electrical characteristics. After the
test, the connectors shall meet the contact resistance requirements of 3.5.10.
3.5.16 Permeability (when applicable). When unmated connectors and connector assemblies with
metal parts and mounting hardware are tested as specified in 4.6.18, the measurements shall be 2.0 mu,
maximum.
3.5.17 Fungus resistance. When connectors are tested when specified in 4.6.21 materials used in the
construction of these connectors shall be fungus inert when tested in accordance with ASTM G21.
3.5.18 Temperature life. When connectors are tested as specified in 4.6.19, they shall meet the
3.5.19 Solderability. When tested in accordance with 4.6.20, the solder termination area shall meet the
requirements of MIL-STD-202, method 208.
3.6 Marking. Connectors are to be marked in accordance with method I of MIL-STD-1285, and are to
include the PIN (see 3.1), the manufacturer's name or code symbol, and date code. The marking shall
remain legible after completion of the tests specified herein.
3.7 Workmanship. Connectors and accessories shall be processed in such a manner, as to be uniform
in quality and shall be free from burrs, crazing, cracks, voids, pimples, chips, blisters, pinholes, sharp
cutting degrees (except wire wrap posts), and other defects that will affect life, serviceability, or
appearance.
