BS ISO 15754:2009 Paper and board. Determination of z-directional tensile strength
BS ISO 15754 specifies a method for the determination of z-directional tensile strength, i.e. the tensile strength in the z-direction. It applies to paper and board, but not to corrugated fibreboard. For papers, the grammage range can not be stated explicitly, but results for papers having a grammage less than 60 g/m2 shall be treated with caution since the tape may reinforce the paper.
BS ISO 15754 does not determine the absolute strength of paper as the measurement is affected by the tape, the pressing conditions and the speed used.
