ISO 2493-1 Bending of Paper and Board

ISO 2493-1 specifies procedures, based on the two-point loading principle, for determining the bending resistance of paper and board. ISO 2493-1 applies to the measurement of the bending resistance within the range 20 mN to 10 000 mN. It is not applicable to corrugated board but can be applicable to the components of such board. The bending angle is 15 degrees and the bending length is 50 mm. For samples having a bending resistance that is too low to measure with a bending length of 50 mm, a shorter bending length, i.e. 10 mm, can be used.
