本程序用于通过测定38 mm（1.5 in.）的弯曲阻力（单位:mN）来测量纸和纸板在机器和机器交叉方向上的弯曲阻力宽垂直夹紧样品，偏转15°或7.5°。对于这种方法，标准弯曲角度为15±0.1°。对于断裂或以其他方式不适合15°的试样，应使用7.5±0.1°的弯曲角度。

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.
