Technical Specifications

Test Principle and Methodology

The Taber Stiffness Tester operates by securely clamping a paper or paperboard sample and applying a controlled bending moment until it reaches the desired bending angle (15° or 7.5°). The stiffness of the material is determined by the resistance offered to this bending, calculated and displayed as a bending moment in mN·m. This bending resistance value is vital for industries that depend on material consistency and performance, helping them evaluate material stiffness and quality.

1. Bending Resistance: Measures the mean bending moment required to bend the test piece, displayed in mN·m.
2. Bending Angle: The angular range through which the clamp rotates, crucial for materials that may undergo deformation if over-stressed.
3. Bending Resistance Index: A calculated value that considers the bending resistance relative to the material’s grammage, providing an index for material comparison.
