3.11 Insert retention. When tested as specified in 4.6.8, unmated connectors shall retain their inserts
in their proper location in the shell and there shall be no evidence of cracking, breaking, separation from
the shell, or loosening parts.
3.12 Air leakage (class T (all receptacles) and class P (MS20029 only)). When tested as specified in
4.6.3, there shall be no evidence of leakage in excess of one atmospheric cubic inch of air per hour (4.55
x 10-3 cm3/s).
3.13 Contact resistance. When tested as specified in 4.6.10, contacts in the mated condition shall
meet the contact resistance requirements of SAE-AS39029. Lead resistance may be included in the
measurement.
3.14 Coupling pin strength. When tested as specified in 4.6.12, bayonet coupling pins shall withstand
a load of 50 (+5, -0) pounds without displacement or perceptible loosening of coupling pins.
3.15 Vibration. When tested as specified in 4.6.13, there shall be no electrical discontinuity and there
shall be no disengagement of the mated connectors, evidence of cracking, breaking, or loosening of
parts.
3.16 Shock. When tested as specified in 4.6.14, there shall be no current discontinuity and there shall
be no disengagement of the mated connectors, evidence of cracking, breaking, or loosening of parts.
