ISO 8791-2:2013规定了使用本特森仪器测定纸和纸板粗糙度的方法。 ISO 8791-2:2013适用于Bendtsen粗糙度值在5 ml/min和3000 ml/min之间（当使用可变面积型测试器测量时）和50 ml/min和5000 ml/min之间（当使用电子型测试器测量时）的纸和纸板。它不适用于允许地面在表面上留下明显印象的软纸，或允许大量气流通过纸张的高透气性纸，或不适用于测量头下方不平坦的纸。

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.
