GB/T 13451.2-1992 "Determination of Relative Tinting Strength of Colored Pigments and Relative Scattering Power of White Pigments—Photometric Methods" specifies the method for determining the relative tinting strength of colored pigments and the relative scattering power of white pigments using photometric methods, applicable to various types of pigments. By preparing pigment dispersions and measuring absorbance or scattering values with a spectrophotometer, the relative values are calculated by comparison with standard samples. The test requires instruments such as a spectrophotometer, grinding equipment, cuvettes, and a constant-temperature water bath, providing a basis for the quantitative evaluation of the coloring properties of pigments.
