Test Method: SATRA TM417

Cleavage test for heel lift lamination strength

April 1997

SCOPE

The method is intended to assess the likelihood of breakdown between layers of an adhesive laminated board heel by measuring the bond strength between any two of the heel lifts. The method is only applicable to laminated compressed wood fibreboard heels.

PRINCIPLE

A slot is sawn into the bond line between two laminated heel lifts. A hardened steel probe mounted in a torque wrench is inserted into the slot and a gradually increasing force is applied until the heel lifts separate. The force required to cause the separation is measured.
