TIA TIA-455-23-A

The intent of this test is to establish the integrity of the seal of the interfaces in a fiber optics device (component or assembly, such as a connector). It may be conducted as one of the tests in a sequential test plan and after or during the exposure of the test sample to a specified low temperature. A pressure differential is established between the front and rear faces of a mounted device. The degree of leakage through the seals of the test sample is measured by means of a detection device located on the low pressure side of the test sample.
