ISO 12625-5Tissue paper and tissue products - Part 5: Determination of wet tensile strength
ISO 12625-5:2005 specifies a test method for the determination of the wet tensile strength of tissue paper and tissue products after soaking with water, using a tensile-strength-testing apparatus operating with a constant rate of elongation. Wet tensile strength is max tensile force per unit width that a test piece soaked with water can withstand before breaking in a tensile test. Wet-tensile-strength-retention is ratio expressed as percentage, of tensile strength of a wet piece to a dry piece from the same sample.
