MIL-DTL-55235A
4.7.10 Leakage. Connectors mated and assembled to their appropriate cables shall be subjected to
a gage pressure of 7.5 pounds per square inch for a period of one minute with the whole connector
immersed in a tank of water at approximately 20ºC. The free end of the cable shall be sealed to prevent
water ingress (see 3.17).
4.7.11 Durability. Connectors assembled to their appropriate cables shall be subjected to 500
applications of insertions and withdrawals at a rate not to exceed 500 cycles per hour. The insertions and
withdrawals shall be conducted in a manner similar to that which the connectors will be subjected to in
service (see 3.18).
4.7.12 Temperature cycling. Connectors mated and assembled to their appropriate cables shall be
subjected to five temperature cycles in accordance with Method 102A of Standard MIL-STD-202 as
follows:
Polytetrafluoroethylene
cables
Polyethylene cables
Time duration
- 55ºC
- 55ºC
30 minutes
+ 25ºC
+ 25ºC
15 minutes
+ 200ºC
+ 85ºC
30 minutes
+ 25ºC
+ 25ºC
15 minutes
Adapters and receptacles shall be subjected to the temperature cycle of
polytetrafluoroethylene cables (see 3.19).
4.7.13 Salt spray. Unmated connectors and connector contacts shall be tested in accordance with
Method 101, Test Condition B, of Standard MIL-STD-202. At the conclusion of the test, the connectors
and connector contacts, shall be washed, shaken, air blasted, and then permitted to dry for 24 hours at
40ºC. The connectors shall be examined for destructive corrosion as defined in 3.20.1. The connector
contacts shall be examined for destructive corrosion as defined in 3.20.2.
4.7.14 Moisture resistance. Connectors mated and assembled to their appropriate cables shall be
tested in accordance with Method 106A of Standard MIL-STD-202 except that the vibration sub-cycle
shall not apply (see 3.21).
4.7.15 Vibration. Connectors mated and assembled to their appropriate cables, and adapters mated
to a plug or jack, as applicable, assembled to its appropriate cable shall be tested in accordance with test
condition A and C of Method 204A of Standard MIL-STD-202 except that the amplitude of the motion
shall be a minimum of 20 gravity units. The connector assemblies shall be subjected to the specified
cycles in each of the two mutually perpendicular directions. The test shall be conducted under the
electrical load conditions of 4.7.16.1, or equivalent to monitor for interruptions of electrical contact of the
mated connectors (see 3.22 and 4.7).
4.7.16 Shock. Connectors mated and assembled to their appropriate cables, and adapters mated to
a plug or jack, as applicable, assembled to its appropriate cable, shall be tested in accordance with test
condition B of Method 202A of Standard MIL-STD-202. The connector assemblies shall be subjected to
six blows of 100 gravity units in each of the two perpendicular positions. The test shall be conducted
under electrical load conditions. The test shall be capable of detecting a 10 microsecond response to
discontinuities to monitor for interruptions of electrical contact of the mated connectors (see 3.22).
