GB/T 13893-2008 "Paints and varnishes - Determination of resistance to humidity - Continuous condensation method" specifies the method for determining the resistance of coatings to humidity using the continuous condensation method, applicable to various types of paints and varnishes coatings. Coated test panels are placed in a condensation test chamber and continuously exposed under specific temperature and humidity conditions to observe changes in the coating's appearance. The test requires instruments such as a condensation test chamber, coating thickness gauge, and magnifying glass, providing a standardized means for evaluating the moisture resistance of coatings.
