GB/T 31410-2015 "Paints and varnishes - Evaluation of wet-scrub resistance and cleanability of coatings" is applicable to the testing of the wet-scrub resistance and cleanability of coatings. A reciprocating scrub resistance tester is used, equipped with a 3M abrasive pad and subjected to a specified load. Under wet conditions, the coating is subjected to reciprocating friction. The color difference of the coating before and after scrubbing is measured using a colorimeter, or the surface damage is assessed visually. The friction speed, stroke, and number of cycles can be adjusted to comprehensively evaluate the durability of the coating during daily cleaning.
