ActiveDetermination of brightness(whiteness) for paper inorganic pigments
造纸无机颜料亮度（白度）的测定
Application Summary AI generated
This standard specifies the method for determining the brightness (whiteness) of inorganic pigments used in papermaking, such as calcium carbonate, kaolin, and titanium dioxide. It is applied in the paper industry for quality control of raw pigments and in testing laboratories to ensure consistent optical properties in coated papers and paperboard. The standard defines the measurement procedure using a spectrophotometer or brightness tester under specific illumination and geometry conditions.
