ISO 3781 – Determination of Tensile Strength After Immersion in Water of Paper And Board
ISO 3781 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.
It is not applicable to tissue paper and tissue products other lightweight, highly absorbent paper which is difficult to handle or of low strength when wet
*** Before conducting ISO 3781 , it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
