GB/T 5211.1-2003 "Determination of water-soluble matter of pigments - Cold extraction method" specifies a method for determining the content of water-soluble matter in pigments using the cold extraction method, which is applicable to various types of pigments. Soluble substances in the pigments are extracted with distilled water at room temperature, and the mass fraction of water-soluble matter is calculated after filtration, evaporation, and weighing. The test requires instruments such as an analytical balance, constant temperature water bath, suction filtration device, and evaporating dish, providing a basis for evaluating the purity of pigments and their suitability for application.
