UNE-EN 302-3:1994 PDF

Scope: This part of the EN 302 Standard describes a method for determining the effect on the resistance of the joint to the attack of wood fibers, caused by the action of acids coming from the adhesive during climatic cycles. It is appropriate for the following applications: a) to assess the conformity of adhesives with respect to Standard EN 301; b) to assess the suitability for use and quality of adhesives used on wood and wooden structures under load; c) to determine if the adhesive after gluing detrimentally influences the resistance of the wood due to chemical action. This test is mainly intended to obtain performance data for the classification of adhesives used in wooden structures under load, according to their suitability for use in defined climatic environments. This test is carried out with spruce (Picea abies L). This method is not intended to provide numerical design data and does not necessarily represent the behavior of the bonded part in service. It is not intended to assess the suitability of adhesives in the construction of wood-based panels.
