SPECIMEN PREPARATION FOR CROSS DIRECTIONAL INTERNAL TEARING RESISTANCE FOR PAPER, PAPERBOARD AND RELATED MATERIALS

Tearing resistance, Cross direction tear, Paper, Paperboard, Nonwovens, Sample preparation

1. 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.
2. 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.

It includes information on:

1. Sampling and test specimen
2. Conditioning
3. Keywords
