Product Description
WTD-02 Taber Stiffness Tester
Application
WTD-02 Taber Stiffness Tester is used to measure the bending resistance of paper and paperboard by the Taber-type tester.
The method is primarily used for papers with a high grammage. In the test, 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, is obtained. For boards that tend to be permanently deformed if bent through 15°, the half bending angle 7.5°, can be used.
The bending resistance is expressed in terms of the bending moment and is expressed in millinewton meters mN·m.
Test Principle
A test piece of defined dimensions is bent through a specified bending angle. The resulting bending moment is read from the instrument scale.
