Based on the Kubelka-Munk theory, this standard specifies a method for calculating the yellowing value by measuring the light scattering coefficient and light absorption coefficient of paper, Cardboard and pulp. It is suitable for white and nearly white paper products, but not for paper containing fluorescent whitening agents. The standard provides a technical means for quantitatively measuring the color change of paper to facilitate the evaluation of the color Stability of paper during use and storage.
