Glued laminated wood. Bond strength test in gluing zones

This specification outlines a standardized procedure for evaluating the adhesive bond quality in layered pressed wood products. It defines the specific methodology required to measure the strength of the bond within the adhesive region by subjecting samples to a controlled peeling action. The document provides detailed instructions on specimen preparation, ensuring consistent dimensions and edge conditions to guarantee reliable test outcomes. It also establishes the criteria for determining the force necessary to separate the layers and specifies the units in which the adhesion strength must be reported.

The approach described in this document focuses on assessing the durability and integrity of the glue line under defined mechanical stress conditions. It is designed to be applicable to various types of wood-based panels where layer bonding is a critical structural element. By following the outlined protocol, laboratories and manufacturers can generate comparable data regarding the performance of adhesive systems used in composite wood materials. The procedure emphasizes precision in the application of force and the measurement of displacement to accurately characterize the bonding characteristics.
