DANSK DSF/FPREN ISO 12625-5 PDF

This part of EN ISO 12625 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. Currently, two types of tensile strength testers are commercially available, one where the test piece is positioned vertically and for the other horizontally. This European Standard applies for both. For vertical tensile strength testers, a device which is held in the lower grip of the tensile strength tester, called a Finch Cup, is used to achieve the wetting. For horizontal tensile strength testers the soaking device is placed between the clamps.
