TAPPI T556 om-05

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 areotherwise unsuitable at 15° a bending angle of 7.5 ± 0.1° shall be used.
