ISO 9416-2021 《Paper Determination of light scattering and absorption coefficients (using Kubelka-Munk theory)》 Related products

This standard provides a method for the determination of light scattering and light absorption coefficients of paper based on the Kubelka-Munk theory. Measurement conditions include the use of instruments with specific Light spectra and geometries for white or near-white paper with less than 95% opacity. The standard requires the exclusion of fluorescence effects in the measurement and provides a convenient calculation method for the evaluation of Optical inspection properties of paper and pulp, ensuring Reliability and conformity of measurement results.
