The ISO 3689:2024 standard specifies a method for determining the bursting strength of paper and Cardboard after soaking in water. This method assesses the wet strength performance of paper and Cardboard samples by measuring their Breaking strength after soaking them in water for a specified period of time. This method is suitable for most paper and Cardboard types, subject to the relevant parties agreeing on a suitable soaking time. The standard provides a uniform wet strength test method for the paper industry, which helps to evaluate the performance of paper in a humid environment, ensuring product mass and safety.
