3.13 Insulation resistance. When connectors are tested as specified in 4.6.10, the insulation
resistance (prior to conditioning) shall not be less than 5,000 megohms.
3.14 Humidity. When connectors are tested as specified in 4.6.11, they shall meet the following
requirements:
Insulation resistance
During the 10th cycle
-
10 megohms minimum
After 24-hour drying period
-
1,000 megohms minimum
Dielectric withstanding voltage

As specified in table II
3.15 Durability. Counterpart connectors shall show no mechanical or electrical defects detrimental to
the operation of the connector after 100 cycles of coupling and uncoupling in accordance with 4.6.12.
The connectors shall be subjected to 50 cycles before and after the corrosion test. No lubricant shall be
applied prior to, during or after the test.
3.16 Salt Spray (corrosion). When tested as specified in 4.6.13, there shall not be sufficient
corrosion to interfere with the mating of the connectors or accessories. Exposure to salt-laden
atmosphere shall not cause corrosion or exposure of the basic metal on any plated metal part such as
shells, adapters, coupling rings or the individual pin and socket contacts submitted which is detrimental to
their mechanical or electrical performance.
3.17 Cable pull-out. When connectors are tested as specified in 4.6.14, test cables (see 4.4.3) shall
not pull-out when the loads given in table V are applied, nor shall slippage exceed .125 inches
(3.18 mm).
