The GJB 150.5-86 standard stipulates the impact test method for the temperature impact test chamber, and is the basis and selection basis for the corresponding part of the technical documents such as technical conditions or product standards for military equipment.
The provisions of GJB 150.1-86 "General Rules for Environmental Test Methods for Military Equipment" apply to this standard.
This standard is applicable to military equipment that may encounter a rapidly changing temperature environment (such as aircraft not controlled temperature cabin equipment, or external, airdrop, air transport equipment).
This standard does not apply to military equipment that is subjected to temperature shock caused by warm air and solar radiation heating and immersed in cold water or subjected to rapid transients caused by the rapid transients of the engine and compressor.
The temperature shock test chamber is mainly used for the adaptability test of electronic, electrical products and their original devices, and other materials when stored, transported and used under the environment of rapid temperature changes. The equipment mainly carries out environmental simulation test on the physical and other related characteristics of the product by placing the test materials under the conditions of rapid changes of high temperature and low temperature. After the test, the performance of the product is judged by the test to meet the requirements.
