Connectors that are designed to resist pressure and leakage due to water exposure must be capable of doing so over an extended duration. The water pressure test is performed by submerging a number of connector samples in six feet of tap water for a period of 48 hours. Half of the connectors are mated throughout the test while the other half are unmated.
After the two-day submersion, the samples are removed from the water and dried. The mated samples are inspected for leakage and the insulation resistance of all the samples is measured.
