The TAPPI T 496 standard specifies the preparation method for transverse internal Tear strength specimens of paper, Cardboard and related materials. The purpose of this standard is to ensure that the preparation process of test samples is uniformly standardized, thereby improving the accuracy and repeatability of test results. The specimen is prepared by cutting to the specified size and ensuring that the transverse (CD) orientation of the sample is consistent with the test orientation. This method is suitable for paper, Cardboard and Miscellaneous fiber materials and is widely used for quality control and product performance evaluation. It provides a standardized sample preparation process for internal Tear strength testing of paper and Cardboard.
