This procedure is used to measure the bending resistance of paper and paperboard in the machine and cross machine directions, by determining the bending resistance in mN of a 38 mm (1.5 in.) wide vertically clamped sample, at 15 or 7.5 deflection. For this method the standard bending angle is 15 0.1. For specimens that break or are otherwise unsuitable at 15 a bending angle of 7.5 0.1 shall be used.
