GB/T 1735-2009 "Paints and varnishes—Determination of heat resistance" specifies the method for determining the heat resistance of coatings of paints and varnishes, and is applicable to the heat resistance evaluation of various types of coatings. The test involves placing coated panels in a constant-temperature oven or high-temperature furnace, aging them under specified temperature and time conditions, and then comparing changes in properties such as appearance, gloss, and adhesion of the coatings before and after the test. The test requires the use of a constant-temperature oven (or high-temperature furnace), a thermometer, a gloss meter, and adhesion testing instruments, providing a basis for evaluating the reliability of coatings in high-temperature environments.
