This standard introduces the damp heat environment, the method of generating humidity, the physical phenomenon of humidity, the acceleration of the physical process, the comparison between the constant damp heat test and the alternating damp heat test, and the influence of the test environment on the test samples, etc. This standard is used for selecting appropriate test methods and severity levels when formulating electrical and electronic product standards; it is also used for product design, manufacturing and test personnel to understand the physical meaning and mechanism of damp heat test, so as to ensure the simulation and reproduction of test results. sex. Damp heat test is mainly used to determine the adaptability of electrical and electronic products to hot and humid environments (whether condensation occurs or not), especially the changes in electrical and mechanical properties of the products; it can also be used to check the ability of test samples to withstand certain corrosion.
