The minimum tensile load required to separate the wire from the contact, either by pulling the wire out of the crimp joint or by

breaking the wire within the crimp joint shall not be less than the applicable limits as specified. Wire breakage or contact damage

not due to crimping at less than tensile loads shall not constitute a failure.

Mated and wired connectors shall exhibit an insulation resistance greater than 100 megohms between all contacts. This limit

shall apply after exposure to each environment including salt solution immersion. Tests shall be performed at 100 VDC ± 10%.

Wired and mated connectors shall show no evidence of breakdown between adjacent contacts when tested at 1000 VDC ± 5%.

Connectors shall meet this requirement after exposure to each environment. Current leakage shall be less than 1.0 milliamp.

The low level contact resistance of mated contacts shall be less than 10 milliohms when measured across the contacts and

crimp joints. The test current shall be a maximum of 100 milliamps with an open circuit test voltage of 20 millivolts maximum.

Connectors shall be subjected to three shocks in each direction applied along the three mutually perpendicular axes of the

connector test specimen for a total of 12 shocks. Each shock shall consist of a terminal peak sawtooth pulse with a peak value

of 100 g's and a duration of 6 milliseconds.

Connectors shall be subjected to random vibration in accordance with MIL-STD-1344, Method 2005.1, test condition VI for 20

hours along each of the following three axes:

Grms

Transverse axis of connector (Y)

Electrical continuity of the connectors shall be monitored during the last 20 minutes sweep in each axis with a test current of 100

milliamps or less and a test voltage less than 2VDC. Electrical discontinuities in excess of 10 microseconds shall be cause of

failure.

Connectors shall be subjected to 25 cycles of mating and unmating at room temperature. Following this test there shall be no

evidence of damage to the contacts, contact plating, connector housing or seals which may prove detrimental to reliable

performance of the connector.

Contacts shall not be displaced greater than 0.030 inches from the connector body when a force of 10 pounds is applied. When

this test follows maintenance again the same contacts shall be tested.

Shall consist of subjecting each wired receptacle to 4 cycles of removal and reinsertion of 20% of the contacts or a minimum of 6

per connector with approved tooling.

The maximum force required to mate the plug and receptacle shall be 25 pounds. The maximum force required to separate the

plug and receptacle shall be 15 pounds. The rate of travel shall be one inch per minute.

Connectors shall be subjected to the following fluids at the temperature and length of time specified. Following the fluid

dip or immersion, the connectors shall be immersed to a depth of 2 to 12 inches in a 5% salt-water solution for 24

hours at room temperature. At the completion of the salt-water immersion test, while still immersed, the connectors

shall meet the insulation resistance requirement specified herein.

(1) Dip: Connectors shall withstand a one second dip and a three minute air dry for a total of 80 cycles.

(2) Immersion: Connectors shall withstand immersion for one hour.

Connectors shall be subjected to a temperature of 125°C ± 3°C for a period of 1000 hours. At the end of the temperature soak

period and after removal from the chamber, the connectors shall meet the insulation resistance and dielectric withstanding

voltage requirements specified herein. Connectors shall be operated at rated current throughout the duration of the temperature

life test. Upon removal from the chamber at the conclusion of the test, the connectors shall show no visual signs of damage,

which may be detrimental to the performance of the connector.

Connectors shall be subjected to 100 thermal cycles from -40°C to +125°C. One cycle shall consist of the transitions from room

temperature to -40°C to +125°C, and from 125°C to room temperature. One cycle shall be accomplished in a three-hour period

with a minimum stabilization period of 15 minutes at each temperature extreme. The chamber temperature transition rate shall

be a minimum of 1.30°C per minute and a maximum of 6.00°C per minute.
