GB/T 44749.2-2024 Adhesives—Test methods for the evaluation and selection of adhesives for indoor wood products—Part 2:Resistance to delamination in severe environments

Scope

This document describes the test method for anti-delamination of adhesives used on wooden products in harsh environments. It provides a selection guide for adhesive/wood combinations in environments where products are exposed to extreme changes in temperature and humidity. The document offers a series of cyclic tests under different temperatures and humidity conditions to verify whether the selected adhesive or the products bonded by the adhesive meet the corresponding anti-delamination requirements.
This document aims to assist users in selecting suitable adhesives and evaluating adhesives and wooden products bonded by adhesives.
This document is applicable to the determination of anti-delamination of indoor wooden products adhesives in non-harsh environments. Other adhesive products can be used as reference.
This document is not applicable to the determination of structural components.
Note: When testing actual bonded products using this method, the test results may not be comparable due to the fact that test laboratories typically cannot control the assembly method of the products.
