标准摘要
[中文适用范围]： ISO 8791 的这一部分规定了使用 Bendtsen 装置测定纸和纸板粗糙度的方法。 ISO 8791 的这一部分适用于用可变面积型测试仪测量时本特森粗糙度值在约 5 毫升/分钟到 3000 毫升/分钟之间，以及在用可变面积型测试仪测量时本特森粗糙度值在约 50 毫升/分钟到 5000 毫升/分钟之间的纸和纸板。 电子型式测试仪。 它不适用于允许土地在表面上留下显着压痕的软纸，或允许大量空气流过纸张的高透气性纸张，或不能平放在纸张下的纸张。 测量头。 [外文原描述]： 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.
