38、oaking with water, using a tensile-strength-testing apparatus operating with a constant rate of elongation.Currently, two types of tensile-strength-testing apparatus are commercially available, one where the test piece is positioned vertically and, for the other, horizontally. This document applies
39、for both. For vertical tensile-strength-testing apparatus, a device which is held in the lower grip of the tensile-strength-testing apparatus, called a Finch Cup, is used to achieve the wetting. For horizontal tensile-strength-testing apparatus, the soaking device is placed between the clamps.In cas
40、es where impurities and contraries have to be determined, ISO 157556applies for these detections in tissue paper and tissue products.2 Normative referencesThe following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

47、ile-strength-testing apparatus that measures and records the tensile force as a function of the elongation of the test piece.The test can be carried out by a vertical or a horizontal tensile-strength-testing apparatus.In order to wet the test pieces for a vertical tensile-strength-testing apparatus,
48、 a device called a Finch Cup, which is held to the lower clamp, is used. For a horizontal tensile-strength-testing apparatus, a soaking cup is inserted between the clamps.From the wet tensile strength and the tensile strength of the same sample in the dry conditioned state, the wet-tensile-strength retention can be calculated.Precision data are available in Annex A.5 Apparatus5.1 Vertical tensile-strength-testing apparatus5.1.1 Tensile-strength-testing apparatusThe tens
