China Standard: GB/T 455-2002 Paper and board determination of tearing resistance

This standard specifies a method for determining the tearing resistance of paper.

This standard also applies to light boards if the tearing resistance is within the range of the instrument.

This standard does not apply to corrugated fiberboard, but it may be applied to the component of such boards; it is not suitable for determining the cross-direction tearing resistance of highly directional paper.
