标准摘要
[中文适用范围]： 本文件规定了测定薄页纸穿孔线拉伸强度的试验方法。 它使用以恒定伸长率运行的拉伸测试设备。 该方法仅用于测量纵向拉伸强度，即薄纸上的横向穿孔。 本文件还规定了射孔效率的计算。 [外文原描述]： This document specifies a test method for the determination of the tensile strength of perforated lines of tissue paper. It uses a tensile-testing apparatus operating with a constant rate of elongation. This method is only used for measuring machine-direction tensile strength, that is for cross-direction perforations on tissue paper. The calculation of perforation efficiency is also specified in this document.
