Paper and board -- Determination of roughness/smoothness (air leak methods) -- Part 3: Sheffield method

ISO 8791-3:2017 specifies a method for the determination of the roughness of paper and board using the Sheffield apparatus.

ISO 8791-3:2017 is applicable to papers and boards which have Sheffield roughness values between 10 ml/min and about 3 000 ml/min. It is not suitable for soft papers which allow the lands of the test head to indent the surface, or for high air-permeance papers which allow a significant flow of air through the sheet, or for papers which will not lie flat during the test.
