Tissue paper and tissue products -- Part 12: Determination of tensile strength of perforated lines -- Calculation of perforation efficiency
This standard was last reviewed and confirmed in 2015. Therefore this version remains current.
ISO 12625-12:2010 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 ISO 12625-12:2010.
