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
-5
3
atmosphere (1.04 x 10 atmospheres cm /s). The specified leakage rate shall apply only through the connector and
not through the flange to the mounting surface joint.
3.5.13 Humidity. Connectors shall meet the applicable dielectric withstanding voltage and insulation resistance
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
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
TABLE IX. Oversize pin exclusion.

3.5.19 Resistance to test probe damage. Socket contacts shall meet the engaging and separating force
requirements specified in 3.5.10 and shall show no evidence of visible damage when tested as specified in 4.5.21.
3.5.20 Fluid immersion. Connectors shall mate within the forces specified in 3.5.4 after being subjected to the fluid
3.5.21 Insert retention.
3.5.21.1 Insert retention (classes D, G, M, and N). Inserts shall not be dislocated from their original positions with
