ISO 12625-4Tissue paper and tissue products - Part 4: Determination of tensile strength, stretch at break and tensile energy absorption
Specifies a test method for the determination of the tensile strength, stretch at break and tensile energy absorption of tissue paper and tissue products. It uses a tensile-testing apparatus operating with a constant rate of elongation.
It also specifies the method of calculating the tensile index and the tensile energy absorption index.
