3.6.10 Insert retention. Connector inserts shall not show evidence of physical damage when tested as
specified in 4.5.11.
3.6.11 Resistance to test prod damage (size 16 socket contacts). When tested as specified in 4.5.12,
the socket contacts shall be capable of withstanding the contact separation test of 4.5.10.
3.6.12 Moisture resistance. When tested as specified in 4.5.13, connectors shall meet a potential test
of one and one-half times the ac voltage specified in table VI for a period of 5 minutes between any pair of
contacts or any contact to shell.

3.6.13 Air leakage, type JS receptacle (not applicable to styles 007C and 016C). When pressurized
connectors are tested as specified in 4.5.14, there shall be no leakage in excess of 1 cubic inch (16.4
milliliter) per hour of air at a pressure differential of 30 psi (2.07 kilopascal).
3.6.14 Thermal shock. When tested as specified in 4.5.15, connectors shall not show evidence of
physical damage after being subjected to temperature cycling test from +125°C to -55°C.
3.6.15 Salt spray (corrosion). When tested as specified in 4.5.16, exposure to a salt laden atmosphere
shall not cause sufficient corrosion to interfere with mating or unmating the connectors. There shall be no
exposure of the base metal on the 25 sets of individual pin and socket contacts subjected to the test. The
connectors shall meet a potential test of twice the ac voltage specified in table VI.
3.6.16 Solderability. Solderable, contact terminations shall withstand the test specified in 4.5.17, unless
solder cup terminations are specified. For solder cup terminations contacts may be removed from the
insulator or an alternate method using a hand iron may be used on the contacts in an assembled (non-
removed) configuration.
