ISO 12625-4-2022 《Tissue paper and tissue products - Part 4: Determination of tensile strength, stretch at maximum force and tensile energy absorption》 Related products

The standard defines methods for determining tensile strength, elongation at maximum tensile force, and tensile energy absorption of toilet paper and tissue paper products. Testing is carried out using tensile testing equipment with constant elongation. The standard also includes methods for calculating the tensile index and tensile energy absorption index. This edition of the standard introduces Appendix B, which is used to describe the determination method of tensile modulus, replacing the technical revision of the 2016 version. The standard provides detailed test specifications and calculation methods for the quality control of paper and cardboard, ensuring the accuracy of the performance evaluation of paper products in actual use.
