Overview
This European Standard specifies requirements and conformity criteria for the identification test, performance (including durability aspects) and safety of injection products for the repair and protection of concrete structures, used for the following: - force transmitting filling of cracks, voids and interstices in concrete (category F); - ductile filling of cracks, voids and interstices in concrete (category D); - swelling fitted filling of cracks, voids and interstices in concrete (category S). The requirements in this part of this standard series are not applicable to highly specialised applications in extreme environmental conditions, such as cryogenic use; they also do not cover specialised circumstances such as accidental impact, for instance due to traffic or ice, or earthquake loading; in these instances specific performance requirements exist. This European Standard is not applicable for: - the treatment of cracks by widening them and sealing them with an elastomeric sealing compound; - external filling of cavities, that is, the placement of product outside the structure (generally within the surrounding foundation soils, or at the interface between the structure and the soil). This is covered by EN 12715 (under contact grouting); - preliminary injection works, if necessary, to temporarily stop water passage during waterproofing injection. The committee responsible for this standard is NA 005-07-06 AA "Schutz, Instandsetzung und Verstärkung (SpA zu CEN/TC 104/SC 8)" ("Protection, repair and strengthening of concrete structures (national mirror committee for CEN/TC 104/SC 8)") at DIN.
