TAPPI T 496 sp-19 Specimen Preparation for Cross Directional Internal Tearing Resistance for Paper, Paperboard and Related Materials

standard by Technical Association of the Pulp and Paper Industry, 2019

Full Description

This practice is used for the preparation of test specimens for the internal tearing resistance of paper, board and related materials when a force is applied perpendicular to the machine direction. Materials whose structures are highly directional cannot be properly tested in their cross direction according to TAPPI T 414 "Internal Testing Resistance of Paper," because, as a rule, the tear turns toward the machine direction as it proceeds. Consequently, it is usually impossible to make a test tear of such a material truly in the cross direction.
