3.5.11.1 Temperature cycling (classes D, K, and M). There shall be no damage detrimental to connector operation

after being subjected to testing

specified in 4.5.13.1. Following the test, the connectors shall withstand the sea level

dielectric withstanding voltage specified in table III.

3.5.12 Air leakage (classes H and K connectors). When tested as specified in 4.5.14, the air leakage rate of

classes H and K connectors shall be no greater than one micron cubic foot per hour at a differential of one atmosphere

(1.04 x 10

the flange to the mounting surface joint.

3.5.13 Humidity. Connectors shall meet the applicable dielectric withstanding voltage and insulation resistance

requirements (see 3.5.6 and 3.5.8) when tested as specified in 4.5.15.

3.5.14 Vibration. Mated connectors shall not be damaged and there shall be no loosening of parts due to vibration.

Counterpart connectors shall be retained in engagement and there shall be no interruption of electrical continuity or

current flow longer than 1 microsecond when tested as specified in 4.5.16.

3.5.15 Shock. Mated connectors shall not be damaged and there shall be no loosening of parts, nor shall there be

an interruption of electrical continuity or current flow longer than 1 microsecond during the exposure to mechanical

shock, as specified in 4.5.17.

3.5.16 Durability. Counterpart connectors shall show no mechanical or electrical defects detrimental to the

operation of the connector, as specified in 3.5.4 and 3.5.10, after 500 cycles of mating and unmating as specified in

4.5.18.

3.5.17 Salt spray (corrosion). Mated connectors shall show no exposure of base metal due to corrosion which will

affect performance as specified in 3.5.4, 3.5.5, 3.5.8, and 3.5.9 when tested as specified in 4.5.19.

3.5.18 Oversize pin exclusion. Socket contacts shall exclude the entry of the test pin specified in table IX when

tested as specified in 4.5.20. After testing, the contacts shall meet the contact resistance requirements

specified in

3.5.9.
