Paper and board — Determination of resistance to bending

Applies to the measurement of the resistance to bending within the range 20 mN to 10 000 mN, but on some instruments down to about 2 mN. Does not apply to corrugated boards but may be applied to the components of such boards. The method is based on the beam principle and is applicable only to instruments which use a bending angle of 7,5° or 15°.
