MIL-DTL-21097G
3.11 Temperature cycling. When connectors are tested as specified in 4.6.7, there shall be no evidence of physical
damage. Upon completion of test, insulation resistance and dielectric withstanding voltage shall meet the requirements
3.12 Vibration. When complete connector assembly, printed wiring board, and receptacle are tested as specified in
4.6.8, there shall be no cracking, breaking, or loosening of parts. There shall be no loss of electrical continuity of any
contact circuits for a period greater than one microsecond.
3.13 Shock. When connectors are tested as specified in 4.6.9, there shall be no evidence of mechanical failure of
metallic or dielectric materials. There shall be no loss of electrical continuity of any contact circuits for a period greater
than one microsecond. Upon completion of testing, the engagement and separation forces shall meet the requirements
3.14 Bond strength, body assembly. Where applicable, when the insulating body of the connector is constructed of
two or more parts, the connector shall be tested as specified in 4.6.10. The connector shall show no evidence of
cracking, breaking or loosening of parts, or delamination of the assembly when a force of 1 pound per position is
applied.
3.15 Contact retention.
3.15.1 Crimp and solder type CR contacts. When connectors are tested as specified in 4.6.11, the contacts shall
withstand an axial load of 10 pounds.
3.16 Board insertion force (overstress). When connectors are tested as specified in 4.6.12, there shall be no
evidence of physical damage. The engagement and separation forces shall meet the requirements of 3.10.1 or 3.10.2,
as applicable.
3.17 Humidity. When connectors are tested as specified in 4.6.13, the insulation resistance of the connector shall be
not less than 1,000 megohms.
3.18 Durability (board side) (applicable only to types A, AD, and CR). When connectors are tested as specified in
4.6.14.1 or 4.6.14.2, the body and contacts shall show no evidence of physical damage. Unless otherwise specified
(see3.1), the contact resistance shall meet the requirements of 3.9, and the individual contact separation force shall be
not less than 1 ounce.
3.19 Salt spray (corrosion). When connectors are tested as specified in 4.6.15, any corrosion resulting from the salt
spray test shall not interfere with the mating or unmating of the printed wiring board and receptacle and shall not impair
the electrical function of the connector.
3.20 Low-signal level contact resistance. When connectors are tested as specified in 4.6.16, the resistance of any
contact shall not exceed 7 milliohms, unless other wise specified (see 3.1).
3.21 Crimp resistance. When contacts are tested as specified in 4.6.17, crimp resistance shall not exceed the
potential drop requirements of table VI.
3.22 Current cycling (crimp). When contacts are tested as specified in 4.6.18, they shall withstand 50 cycles of
exposure to 125 percent of the test current without exceeding the "after test" voltage drop specified in table VI.
