Method 4.5.17 is a thermal shock test for filter connector adapters. Adapters are tested in accordance with method 107 of MIL-STD-202 with the applicable test condition letter specified.
Measurements before and after cycling are not applicable for this test. The thermal shock cycling subjects the adapter to rapid temperature transitions to evaluate material integrity and seal performance.
This test verifies that filter connector adapters can withstand the thermal stresses encountered in military environments without cracking, delamination, or loss of hermetic seal.
