GB/T 1722-1992 "Method for Determination of Color of Varnishes, Boiled Oils and Thinners" specifies the method for determining the color of varnishes, boiled oils, and thinners using the platinum-cobalt colorimetric method. The sample is compared with standard platinum-cobalt colorimetric solutions in Nessler tubes to determine the color grade, which is applicable for the appearance quality control of transparent liquid coating products. The test requires equipment such as platinum-cobalt standard colorimetric solutions, Nessler tubes, and tube racks, and the operation is simple and intuitive.
