DIN ISO 3781:2012-07

This document has been elaborated by the adoption of ISO 3781:2011. The International Standard has been prepared by ISO/TC 6/SC 2 "Test methods and quality specifications for paper and board", the secretariat of which is held by SIS (Sweden). The International Standard has been translated by the Paper, Board and Pulp Standards Committee (NPa) at DIN e. V. This International Standard specifies a test method for the determination of the wet tensile strength of paper or board after its immersion in water for a specified period. In principle, the method is applicable to both paper and board, provided an appropriate soaking time is agreed between the interested parties. This International Standard is not applicable to tissue paper and tissue products. ISO 12625-5 shall be used for this issue.
