标准范围

ISO 8791-3:2017规定了使用谢菲尔德仪器测定纸和纸板粗糙度的方法。ISO 8791-3:2017适用于谢菲尔德粗糙度值在10 ml/min至约3000 ml/min之间的纸张和纸板。它不适用于允许测试头边缘在表面凹陷的软纸，或允许大量空气流过纸张的高透气性纸张，或在测试期间不会平躺的纸张。

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.
