BS DIN EN 314-1 Plywood Bond Quality Test Machine

This standard specifies methods for determining the bonding quality of veneer plywood, by shear testing.

Before carrying out the shear tests the plywood samples are required to undergo a sequence of pre-treatments e.g. section 5.14 calls for immersion for 72 hours (±1) in boiling water followed by cooling in water at 20°C (±3°) for at least 1.

Annex A in the standard covers the determination of the percentage of apparent cohesive wood failure by comparison to reference illustrations of the texture of failed surfaces.

Annex B provides guidelines for the evaluation of the glue bond of insulating core plywood.
