UNE-EN ISO 12625-5:2025

This document specifies a test method for the determination of the wet tensile strength of tissue paperand tissue products after soaking with water, using a tensile-strength-testing apparatus operating witha constant rate of elongation.Currently, two types of tensile-strength-testing apparatus are commercially available, one wherethe test piece is positioned vertically and, for the other, horizontally. This document applies for both.For vertical tensile-strength-testing apparatus, a device which is held in the lower grip of the tensilestrength-testing apparatus, called a Finch Cup, is used to achieve the wetting. For horizontal tensilestrength-testing apparatus, the soaking device is placed between the clamps.In cases where impurities and contraries have to be determined, ISO 15755[6] applies for thesedetections in tissue paper and tissue products.
