This Part of EN 302 describes a method of determining the strength in longitudinal shear of adhesive bonds between lap joint test pieces made of beech (Fagus sylvatica L). It is suitable for the following applications:
a) for assessing the compliance of adhesives with EN 301;
b) for assessing the suitability and quality of adhesives for load-bearing timber structures;
c) for comparing the strengths of bonds with thin or thick glue-lines.
This test is intended primarily to obtain performance data for the classification of adhesives for load-bearing timber structures according to their suitability for use in defined climatic environments.
This method is not intended for use to provide numerical design data and does not necessarily represent the performance of the bonded member in service. It is not applicable to assessment of the suitability of adhesives for the manufacture of wood-based panels.
