TAPPI T496 sp-13

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.
