GB/T 21867.1-2008 "Pigments and extenders - Methods of assessment of dispersibility - Part 1: Assessment from the change in tinting strength of coloured pigments" specifies the method for assessing the dispersibility of coloured pigments through the change in tinting strength, and is applicable to various types of coloured pigments. After dispersing the pigment, a color paste is prepared and compared with a standard sample for tinting strength. Better dispersibility results in higher tinting strength. The detection requires instruments such as a spectrophotometer, grinding equipment, and standard color charts, providing a quantitative basis for evaluating the dispersion effect of pigments.
