3.6.4 Mating and unmating force. When tested as specified in 4.7.5, the force for mating and unmating of counterpart
connectors shall meet the requirements of table III. When connectors are mated to the torque values of table III the maximum
allowable dimension between flanges shall be .320 inch (8.13 mm). The connectors used for this test shall have the complete
complement of contacts.

3.6.5 Contact retention. When tested as specified in 4.7.6, the axial displacement of the contacts shall not exceed .012 inch
(0.30 mm) while under load. For classes G, E, P, contacts shall be retained in their inserts.
3.6.6 Dielectric withstanding voltage. When tested as specified in 4.7.7, unmated connectors shall show no evidence of
breakdown or flashover. Corona shall not be considered as breakdown.
3.6.7 Insulation resistance. When tested as specified in 4.7.8, the insulation resistance of mated and unmated connectors shall
conform to the requirements of table IV (see 3.1).
