TAPPI T 556 – Bending resistance of paper and paperboard by single-point bending method
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.
