GB/T 2423.4-2008 "Environmental Testing for Electric and Electronic Products - Part 2: Test Methods - Test Db: Damp Heat, Cyclic (12h + 12h Cycle)" specifies the standard method for conducting cyclic damp heat tests on electric and electronic products, utilizing a 24-hour cycle consisting of 12 hours of high temperature and high humidity followed by 12 hours of low temperature and high humidity. This test is primarily used to assess whether the electrical and mechanical performance of products changes under conditions of cyclic temperature variations and surface condensation, as well as to evaluate the moisture resistance of materials and structures.
