The standard "GB/T 26464-2011 Determination of luminance (whiteness) of inorganic pigments in papermaking" specifies the method for measuring the luminance (whiteness) of white inorganic pigments for papermaking. The standard is applicable to various white inorganic pigments used in the papermaking industry. By drying, grinding, tableting, etc., the sample is then measured under specified conditions to determine its reflection factor to blue light to evaluate its luminance (whiteness). The standard uses the blue light diffuse reflection factor as the measurement basis to ensure that the luminance evaluation of pigments is accurate and reliable.
