GB/T 9281.1-2008 "Clear liquids - Estimation of colour by the Gardner colour scale - Part 1: Visual method" specifies the visual method for determining the Gardner colour grade of clear liquids, applicable to petrochemical products such as aromatics, solvents, and related clear liquids. The colour grade is determined by comparing the sample with Gardner standard colour glass slides. The test requires instruments such as Gardner colour standard glass slides, colorimetric cells, and standard light source boxes, providing a basis for quality control of clear liquid colour in specific fields.
