scope:

This Part of the Standard 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 NEN-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 stressess 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.
