GB/T 5211.16-2007 "Comparison of Lightening Power of White Pigments" specifies the comparative method for determining the lightening power of white pigments, which is applicable to various types of white pigments. The test involves preparing color pastes by mixing the sample and the standard pigment with a specified colorant, respectively. The depth of color is compared through visual colorimetry or spectrophotometry to determine the strength of the lightening power. The testing requires instruments such as grinding equipment, colorimetric cells, spectrophotometers, and standard light boxes, providing technical support for the evaluation and selection of the coloring properties of white pigments.
