Scope

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.
