scope:

This test is conducted for the purpose of determining the resistance of a given electrical connector or socket to exposure at extremes of high and low temperatures and to the shock of alternate exposures to these extremes, simulating the worst probable conditions of storage, transportation and application.

NOTE - This procedure includes the provision for testing at cryogenic temperatures. Cryogenic temperatures should only be used with specimens specifically designed to be compatible with such temperatures.

Test designation

This test procedure contains 2 test methods; each test method has multiple test conditions - see current designations in table 1. This test procedure has multiple test duration options (number of cycles) - see table 5.

Method A is for air-to-air thermal shock.

Method B is for air-to-liquid nitrogen (cryogenic) thermal shock.
