International Standard
85.060 Paper and board
ISO 8791-2:2013 specifies a method for the determination of the roughness of paper and board using the Bendtsen apparatus.
ISO 8791-2:2013 is applicable to paper and board which have Bendtsen roughness values between about 5 ml/min and 3 000 ml/min when measured with variable-area type testers and between about 50 ml/min and 5 000 ml/min when measured with electronic type testers. It is not suitable for soft papers which allow the land to make a significant impression on the surface or for high-air-permeance papers which allow a significant flow of air to pass through the sheet, or for papers which will not lie flat under the measuring head.
