Description

This Standard describes 'Method 2' for determining the quality of bond in plywood.

Scope

In a well-made glueline, the separation of plies occurs, predominantly, through breaking of the wood itself and not by separation of the plies along the glueline. A satisfactory glueline will therefore include a substantial amount of adhering wood fibre when the plies are forcibly separated. Consequently, the proportion of fractured wood adhering to both plies will provide a measure of the quality of the bond.

This Standard describes the process and test procedures for testing the bond quality of veneer and plywood.
