ActiveDetermination of matter soluble in water of pigments--Cold extraction method
颜料水溶物测定 冷萃取法
Application Summary AI generated
This standard specifies a cold extraction method for determining the water-soluble matter content in pigments. It is applied in the paint, coating, and ink industries to assess pigment purity and quality by measuring the amount of soluble salts or impurities that can be extracted with water at room temperature. The method is particularly relevant for quality control testing of pigments used in water-based systems or where soluble contaminants could affect performance.
