This document specifies test methods for the determination of the suitability of two- component epoxy and polyurethane adhesives for on-site repair of cracks in timber structures made of solid wood, finger-jointed solid wood, glued solid timber and glued laminated timber made of softwood species by injection of the repair adhesive. The adhesive can also be used to rehabilitate cracks in the area of joints made by nails, screws, dowel-type fasteners and dowels with threads. The adhesive can also be used to fill gaps between the faces of structural components. This document specifies minimum requirements on bond strength and integrity and dimensions of fissures, cracks and openings. This document provides also minimum on-site repair provisions and specifies quality control tests at the structures repaired by bonding.

This document also covers the repair of surface treated wood. It does not cover the repair of modified and stabilized wood with considerably reduced swelling and shrinkage properties, e.g. such as acetylated wood, heat treated wood, polymer impregnated wood and preservative treated wood.

The adhesive is intended for the repair of load bearing timber structures not subjected to temperatures more than 60 °C over a longer time in service classes 1 and 2, see EN 1995-1-1 which are loaded predominantly static or quasi static, see EN 1990 and EN 1991-1-1. A verification of quality and glue line integrity of the on-site repair bonding is given in an informative Annex A.
