The Internal Bond™ Tester is designed to determine the internal bond strength of a variety of Paper and Board materials according to TAPPI T 569 and ISO 16260. The instrument design is based on a falling pendulum which creates a high speed impact on a paper specimen. The paper specimen is sandwiched between two double-coated tape substrates. The pendulum impact measures the total energy required to delaminate the internal fibers of a specimen in a “Z” type direction into two plies.

Several Pendulum ranges available:

• 0 – 841 J/m² (0 -400 ft.lb x 10-3)
• 315 – 1575 J/m² (150 – 750 ft.lb x 10-3)
• 420 – 2100 J/m² (200 – 1000 ft.lb x 10-3)

Pendulums must be ordered separately, please specify when ordering. A pendulum is required for the operation of the unit.
