The ISO 3781:2011 standard specifies the method for determining the wet tensile strength of paper and Cardboard after soaking in water. This method is suitable for paper and Cardboard, provided that the relevant parties have agreed on an appropriate soaking time. For testing, after the sample has been soaked in water for a certain period of time, it is removed and immediately tested for tensile strength. This standard is used to evaluate the durability and Stability of paper and Cardboard in a humid environment. It is an important means of quality control and product performance evaluation, especially for paper products in industries such as Encasement and printing.
