本文件规定了使用Taber型测试仪测量纸张和纸板抗弯性的程序。 本文件用于确定在弯曲长度为50 mm时，将38 mm宽垂直夹紧试样的自由端偏转15°所需的弯矩。对于弯曲15°后容易永久变形的板材，可以使用半弯曲角，即7,5°。弯曲阻力以弯矩和Taber型测试仪制造商设置的参数表示。 这种方法主要用于高克数的论文。 注:本文件不包括使用10 mm弯曲长度的泰伯式仪器的低量程版本（见参考文献[5]）。

This document specifies procedures to measure the bending resistance of paper and paperboard using a Taber-type tester. This document is used to determine the bending moment required to deflect the free end of a 38 mm wide vertically clamped specimen by 15° when the load is applied at a bending length of 50 mm. For boards that tend to be permanently deformed if bent through 15°, the half bending angle, i.e. 7,5°, can be used. The bending resistance is expressed in terms of the bending moment and parameters set by the manufacturer of the Taber-type tester. The method is primarily used for papers with a high grammage. NOTE This document does not cover the low-range version of the Taber-type instrument that uses a bending length of 10 mm (see Reference [5]).
