This document specifies a method of determining the ability of adhesive bonds to resist long-term sustained load applied vertical to the glue lines. It is applicable to adhesives used in load-bearing timber structures.
It is applicable for the following applications:
a) for assessing the compliance of adhesives according to EN 15425 and EN 16254;
b) for assessing the effect on the bond strength resulting from long-term sustained load at cyclic climate conditions.
This method 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 to provide data for structural design and does not necessarily represent the performance of the bonded member in service.
