MIL-DTL-22992G
3.18 Vibration. When the wired connector assembly is tested as specified in 4.6.15, there shall be
no loss of electrical continuity in excess of 10 microseconds, and there shall be no cracking, breaking, or
loosening of parts.
3.19 Drop (class L). When connectors are tested as specified in 4.6.16, there shall be no breaking or
cracking of inserts, bending of pins nor any other damage which prevents the connectors from being
mated or renders them unfit to continue further testing. Any chipping of the inserts which affects its
polarization or retention in the shell shall be considered a failure.
3.20 High-impact shock. When connectors are tested as specified in 4.6.17, there shall be no
evidence of damage or discontinuity of current in excess of 10 microseconds. The connectors or
accessories shall not loosen or become disengaged.
3.21 Water immersion. When tested in accordance with 4.6.18, the receptacle inserts and panel
seals shall show no leakage. There shall be no evidence of water leakage at the connector interface of
mated connectors, nor shall there be evidence of leakage in the cable adapters of the mated or unmated
plugs or between the protective caps and the connector interface. At the end of 4 hours while the mated
plugs are still immersed, the insulation resistance shall be 100 megohms minimum. After removal of
unmated connectors from the immersion tank, the insulation resistance shall be 100 megohm minimum.
3.22 Heat rise (class L). When connectors are tested as specified in 4.6.19, the temperature rise of
the individual contact terminals shall be not more than 30C (54F) above ambient temperature. There
shall be no evidence of physical damage.
3.23 Arc rupture (class L). When connectors are tested as specified in 4.6.20, they shall withstand
the test current in table VI. There shall be no electrical or mechanical damage which would prevent the
connectors from being fully mated and unmated by hand. Flexible spring members of contacts shall not
weld together. Any arc drawn while mating or unmating connectors under maximum load will be
extinquished before the pin contact leaves the socket contact insert chambers. Contacts shall maintain
shape and there shall be no excessive vaporization of metal or contact distortion. Following the test, the
connectors shall meet the following requirements:
Insulation resistance
- 100 megohms minimum
Dielectric withstanding voltage - as specified in table II

3.24 Fluid immersion. When connectors are tested as specified in 4.6.21, they shall mate properly
with their counterpart connectors and withstand one-half the applicable voltage stipulated in table II.
