Scope: This standard specifies the evaluation method for evaluating the dispersibility of colored pigments based on tinting strength. This part should be read together with GB/T 21868.1-2008. The method is generally applicable to comparisons of like pigments, eg a test pigment with an agreed reference pigment.
