Description
Test
Method
Results
Moisture Resistant MIL-STD-1344
Method 1002.1 Type II
1. No deterioration of performance.
2. Insulation resistance greater than 100 megohms
3. No evidence of flashover or breakdown during 1000 VAC
DWV testing.
Fluid Immersion
20 hours immersion in hydraulic fluid per MIL-H-5606 1. No detrimental damage.
and lubricating fluid per MIL-L-23699
2. Able to meet requirements of mating and unmating
forces test.
Immersion
Two hour Immersion tap water at a dept of 36.00
(914.40) in mated condition, per MIL-STD-810
Method 512, Procedure 1.
While still immersed, the mated connectors exceeded 100
megohm insulator resistance and exhibited no evidence of
breakdown or flashover during 1000 VAC (RMS) DWV
testing.
