GJB150.4A-2009 Environmental Test Methods for Military Equipment Laboratories Part 4: Low Temperature Test

Low temperature testing is mainly used to evaluate the impact of low temperature conditions on the safety, integrity, and performance of equipment during storage, operation, and disassembly. To determine the sequence of low-temperature tests, two principles should be followed: maximizing the use of the equipment's lifespan and the applied environment should be able to display the superposition effect to the greatest extent possible.
