Best Precise Taber Stiffness Tester Bending Resistance Testing Machine for Paper
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 PrincipleA test piece of defined dimensions is bent through a specified bending angle. The resulting bending moment is read from the instrument scale.
