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.
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]).
