TAPPI T 812 is a laboratory test method used to evaluate the interlayer separation strength of solid and corrugated fibreboards in wet conditions. The standard mainly distinguishes between cardboards produced with weathering resistance gluing agents and non-weathering resistance gluing agents by simulating the performance of cardboards in humid environments. In the test, the cardboard sample is soaked in water, and then the interlayer separation strength is measured. The results can be used to evaluate the durability and Reliability of cardboards in wet conditions, and are an important basis for Cardboard Encasement quality control and performance evaluation.
