ISO 12625-12-2023 "Tissue paper and tissue products - Part 12: Determination of tensile strength of perforated lines and calculation of perforation efficiency"

ISO 1 2625-12: 2023 Toilet paper and tissue products, Part 12: Determination of tensile strength of perforation lines - Calculation of perforation efficiency The standard specifies a method for determining the tensile strength of perforation lines of toilet paper and similar tissue paper products and assessing their separation performance by calculating the perforation efficiency. The method is designed to ensure that the perforation strength is sufficient to maintain the cohesion of the paper, but not too strong, so that users can easily separate the paper. The standard is suitable for assessing the tensile strength of paper along the machine direction and provides the industry with a tool to measure the effectiveness of perforation design.
