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

This document establishes a classification for one component polyurethane (PUR) adhesives according to their suitability for use in load-bearing timber products in defined climatic exposure conditions, and specifies performance requirements for such adhesives for the factory manufacture or factory-like manufacturing of load-bearing timber products only.
It also classifies “adhesive product lines” where all the products within the line have the same chemical composition except for a different amount of catalyst.
This document only specifies the performance of adhesives for use in an environment corresponding to the defined conditions.
The performance requirements of this document are applicable to the adhesives only, not to the manufactured timber products. This document does not cover the performance of adhesives for on-site gluing (except for factory-like conditions) or the production of wood-based panels, except solid wood panels, or modified and stabilized wood with considerably reduced swelling and shrinkage properties, e.g. acetylated wood, heat treated wood and polymer impregnated wood.
This document is primarily intended for use by adhesive manufacturers and for use in timber products bonded with adhesives, to assess or control the quality of adhesives. The requirements are applicable to the type testing of the adhesives. Production control activities are outside the scope of this document.
Adhesives meeting the requirements of this document are adequate for use in load-bearing timber products, provided that the bonding process has been carried out according to an appropriate product standard.
This document does not address the classification and use of adhesives in combination with the spraying of water before or during the bonding process; see informative Annex C of this document.
This does neither allow nor forbid the use of adhesives in combination with the spraying of water.
