适用范围

This Part of EN 302 describes a method for determining the extent to which wood shrinkage under drying conditions will weaken an adhesive bond. It is suitable for the following applications: a) for assessing the compliance of adhesives with EN 301; b) for assessing the usability and quality of adhesives for load-bearing timber structures; c) for establishing whether or not the adhesive is capable of withstanding stresses due to shrinkage of the wood, without unacceptable loss of strength. 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 test is carried out on spruce (Picea abies L.). 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 intended to be used to assess the suitability of adhesives for the manufacture of wood-based panels.
