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.
An automatic sample preparation station (Model 80-30) is available which allows five specimens to be accurately pressed and cut simultaneously. The prep station includes a safety enclosure over the cutting blades, eliminating the use of box cutting knives to separate the individual test specimens.
