MIL-DTL-83513G
4.5.18 Fluid immersion. Unmated connectors shall be immersed fully in the fluids specified below for
the required periods. At least one connector shall be immersed in each fluid. After removal from the
fluid, each connector shall remain for 1 hour in free air at room conditions. Subsequent testing shall be
performed on connectors mated with the same mating connectors used previously in the test. The
connector shall be mated as specified in 4.5.4. The mating force shall not exceed the force requirement
specified in 3.5.2 at the distances denoted on figure 3. Following mating, connectors shall be cleaned in
a suitable solvent to remove the cleaning solvents and lubricating oil.
a. Lubricating oil Aircraft turbine engines, synthetic base: 20 hours.
b. Coolant-dielectric fluid synthetic silicate ester base lubricant (coolanol 25 or equivalent): 1 hour
1 minute.
4.5.19 Insert retention (class M connectors only). Inserts shall be subjected to axial loads in each
direction. Loading shall be accomplished by applying air pressure or equivalent load. The pressure shall
be increased gradually at a rate approximately 10 psi per second until the pressure specified in 3.5.17 is
reached. The insert shall retain its normal position in the connector shell for at least 5 seconds at the
maximum pressure specified in 3.5.17.
4.5.20 Crimp tensile strength (type I contacts only). Specimens of contacts crimped to wires shall be
placed in a standard tensile-testing machine and an axial load shall be applied. The holding surfaces or
clamps of tensile testing machine may be serrated to provide sufficient gripping or holding strength. The
rate of travel of the head of the testing machine shall be approximately 1 inch per minute minimum. The
crimp tensile shall be as specified in 3.5.18.
4.5.21 Low-signal level contact resistance (see 3.5.19). The low-signal level contact resistance test
shall be in accordance with test procedure EIA-364-23. The following detail shall apply: Environmental
conditioning not required.
4.5.22 Thermal vacuum outgassing (space classes only, see 3.5.20). All nonmetallic materials,
including lubricants, used in the manufacture of these connectors shall be tested in accordance with
JSC SP-R-0022 or ASTM E595 to determine the maximum TML of the original specimen mass and the
VCM content of the original specimen mass. For the purpose of determining TML and VCM of
connectors, the original specimen mass shall be the assembled connector mass excluding metallic parts.
The TMC and VCM for the connectors may be determined by testing the specific materials of the
connector and calculating the loss for the connector.
4.5.23 Marking performance. The marking shall meet the requirements specified in 3.6 when tested in
accordance with MIL-STD-202, method 215.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirement shall be as specified in the
contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house
contractor personnel, these personnel need to contact the responsible packaging activity to ascertain
requisite packaging requirements. Packaging requirements are maintained by the Inventory Control
Point's packaging activity within the Military Service or Defense Agency, or within the military service's
system commands. Packaging data retrieval is available from the managing Military Department or
Defense Agency's automated packaging files, CD-ROM products, or by contacting the responsible
packaging activity.
