ISO 8791-3 specifies a test method for measuring paper and Cardboard surface roughness using the Sheffield method. This method is based on the principle of air leakage and is suitable for printing and industrial paper by measuring the rate at which air flows through the paper surface at a certain pressure. The Sheffield method is particularly suitable for materials with relatively low asperity and can effectively evaluate the performance of paper in printing and Spreader processes. The standard provides test equipment, operation procedures and data processing requirements, providing a reliable basis for paper quality control and research and development.
