High and low temperature alternating damp heat test refers to the adaptability test of products during storage, transportation and use under simulated test conditions of high temperature, low humidity, low temperature and high humidity and other different environments. The high temperature test in alternating damp heat test is aimed at the storage or use of products in indoor or confined space or near heat sources such as engine in high temperature season. The purpose is to test the adaptability of military and civil equipment to storage and work in high temperature environment.

The purpose of low-temperature test in alternating damp heat test is to test whether the test pieces can be stored, manipulated, controlled and operated in a long-term low-temperature environment, so as to determine the adaptability of military and civil equipment to storage and work under low-temperature conditions. High and low temperature alternating damp heat test is to detect the temperature and humidity resistance adaptability of products to high and low temperature and damp heat environment, and observe the changes of mechanical and electrical properties of products. Similarly, the alternating damp heat test is also applicable to test the ability of the sample to withstand some corrosion.

Application field of high and low temperature alternating damp heat test:

Road traffic: electronic and electrical equipment of road vehicles, equipment and devices of rail transit rolling stock, auto parts, etc
