Adhesives. One component polyurethane (PUR) for load-bearing timber structures. Classification and performance requirements

BS EN 15425:2008 粘合剂.承载木结构用单组分聚氨酯.分类和性能要求

This European Standard establishes a classification for one component polyurethane adhesives according to their suitability for use in pre-fabricated timber components for structural use in defined climatic exposure conditions, and specifies performance requirements for such adhesives for the industrial manufacture of loadbearing timber structures only. The performance requirements of this European Standard apply to the adhesive only, not to the structure. This European Standard does not primarily cover the performance of adhesives for the production of woodbased panels. This European Standard is primarily intended for the use of adhesive manufacturers and for the use in timber structures bonded with adhesives, to assess or control the quality of adhesives. This European Standard only specifies the performance of an adhesive for use in an environment corresponding to the defined conditions. Such an adhesive meeting the requirements of this European Standard for its type is adequate for use in a load-bearing timber structure, provided that the bonding process has been carried out according to an appropriate product standard.
