Key Features
- Measures the bending resistance of paper, paperboard and other flexible flat-sheet materials
- Balanced pendulum pivoted at its centre of gravity on two jewel bearings
- Pins at different distances for attaching weights below the pivot
- Pointer at the lower end moves parallel to a scale mounted over the base
- Scale graduated in both left and right directions
- Specimen presses against a triangular vane at the upper end of the pendulum

About This Product
Bending resistance, or stiffness, tells how much force is needed to bend a sheet of paper or board, and it affects how the sheet handles in use. A specimen is pressed against the vane of a pendulum, which then swings, and the pointer shows the deflection on the scale. The method is not recommended for soft, limp or creped materials, and tissue or toweling would not normally be tested this way. Materials with a pronounced curl can give erroneous results.
Frequently Asked Questions
Q1. What does the Bending Resistance Tester measure?
It measures the force required to bend a specimen of paper, paperboard or other flexible flat-sheet material under controlled conditions.
Q2. Which materials is it not suited to?
It is not recommended for soft, limp or creped materials. Tissue or toweling would not normally be tested, and materials with a pronounced degree of curl would give erroneous results.
Q3. How does the pendulum register the bend?
The specimen presses against a triangular vane at the upper end of the pendulum and causes it to deflect, and a pointer at the lower end moves over a scale graduated in both left and right directions.
