Method 4.5.5 tests mating characteristics of connectors. After insertion of the specified oversize pin the specified number of times, the contact to be tested is held rigid by a suitable jig or fixture, or a qualified mating connector with the approval of the qualifying activity.
A gauge containing the test pin or test ring and a suitable force-indicating dial is aligned to within 0.004 TIR of any plane passing through the axis of the contact under test. Engagement or withdrawal forces are measured.
This test evaluates the reliability and repeatability of the contact mating mechanism after simulated wear, ensuring proper electrical connection in military filter connector applications.
