适用范围

This part of ISO 8791 specifies a method for the de-termination of the roughness of paper and board using the Bendtsen apparatus. It should be read in conjunction with ISO 8791-1. The method is applicable to paper and board which have Bendtsen roughness values between about 50 ml/min and 1 200 ml/min. 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 heavy metal annulus.
