Determination of Plywood Bonding Strength by Boiling Test

Class II plywood: The specimen was immersed in hot water at 63 3 C for 3 hours and cooled for 10 MIM at room temperature after removal. When impregnating the specimens, all the specimens should be immersed in hot water and covered.

Note: Rapid inspection method of 63 3 C and impregnation for 1 h is allowed in factory production. The measured results multiplied by coefficient 0.82 are used as the bonding strength value of product inspection. However, when there is dispute between suppliers and demanders, the method of 3 h hot water impregnation is still used as the arbitration method.
