GB/T 21867.2-2008 "Pigments and extenders - Methods of assessment of dispersion characteristics - Part 2:Assessment from the change in fineness of grind"

This standard assesses the dispersion of pigments by measuring the change of fineness of ground. It is suitable for the comparison of the dispersion of similar pigments, such as the comparison of test pigments and reference pigments. The standard requires testing under specific dispersion conditions and is used in combination with GB/T 21868.1-2008. The test results can provide a reference for the dispersion effect of pigments in practical applications.
