Abstract This International Standard specifies the equipment for measuring the diffuse reflectance factor of pulp, paper and board and the procedures for calibrating that equipment. Measurements of diffuse reflectance factor are used for the evaluation of optical properties such as diffuse blue reflectance factor (ISO brightness), the scattering coefficient of pulp, opacity, whiteness, luminous re- flectance factor, the chromaticity coordinates of paper and the intrinsic reflectance factor of non-fibrous ma- terials. Numerical values optically characterizing the materials are calculated specifically for each property determined,
