The paper specimen is compressed between two double-coated tape substrates. The pendulum impact measures the total energy required to delaminate the internal fibers of a specimeninto two plies.
Design for determining the Internal Bonding Strength of Paper, Paperboard and Laminates, by measuring the average energy, in thousands of foot pound required to de laminate the specimen in two piles, as described by the TAPPI Routine Control Method RC-308.
A pendulum of dual capacity and free to swing on a housed and dust proof ball bearing.
The range changing weights are available to select the pendulum capacity. A mechanism for holding the pendulum in raised position with a provision instantaneous release.
