Determination of bending resistance — Part 2: Taber-type tester |
ISO 2493-2 Stiffness specifies procedures to measure the bending resistance of paper and paperboard.
This test 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.
This method is primarily used for papers with a high grammage.
A test piece of defined dimensions is bent through a specified bending angle using a specific type of testing instrument. The resulting bending moment is read from the instrument scale.
