GB/T 9282.1-2008 "Transparent liquids - Determination of colour by the platinum-cobalt scale - Part 1: Visual method" specifies the visual method for determining the platinum-cobalt colour grade of transparent liquids, applicable to transparent liquids such as varnishes, solvents, and oils. The method involves comparing the sample with platinum-cobalt standard colorimetric solutions in colorimetric tubes to determine the colour grade. The test requires equipment such as platinum-cobalt standard colorimetric solutions, Nessler tubes, and colorimetric tube racks. The operation is simple and provides a universal method for colour assessment of transparent liquids.
