BS EN 1504, Products and systems for the protection and repair of concrete structures: Definitions, requirements, quality control and evaluation of conformity, is divided into 10 parts.EN 1504 Part 1 Definitions.Defines terms relating to products and systems for repair, for use in maintenance and protection, restoration and strengthening of concrete structures.EN 1504 Part 2: Surface protection systems for concrete.Specifies requirements for the identification, performance (including durability aspects) and safety of products and systems to be used for surface protection of concrete, to increase the durability of concrete and reinforced concrete structures, as well as for new concrete and for maintenance and repair work.EN 1504 Part 3: Structural and non-structural repair.Specifies requirements for the identification, performance (including durability) and safety of products and systems to be used for the structural and non-structural repair of concrete structures.EN 1504 Part 4 Structural bondingThe standard specifies requirements for the identification, performance (incl. durability) and safety of structural bonding products and systems used for the structural bonding of strengthening materials to an existing concrete structure, including:- bonding of external plates of steel or other suitable materials (e.g. fibre reinforced composites) to a concrete surface for strengthening purposes, including the laminating of plates in such applications.- bonding of hardened concrete to hardened concrete, typically associated with the use of precast units in repair and strengthening.- casting of fresh concrete to hardened concrete using an adhesive bonded joint where it forms a part of the structure and is required to act compositely.EN 1504 Part 5 Concrete injectionSpecifies requirements and conformity criteria for identification, performance (including durability aspects) and safety of injection products for:- force transmitting of cracks, voids and interstices in concrete (FTFC)- ductile filling of cracks, voids and interstices in concrete (DFC)- swelling fitted filling of cracks, voids and interstices in concrete (SFFC)EN 1504 Part 6: Grouting to anchor reinforcement or to fill external voidsSpecifies requirements for the identification, performance (including durability) and safety of products for the anchoring of reinforcing steel as part of the repair and protection of concrete structures.EN 1504 Part 7: Reinforcement corrosion protection.Specifies requirements for the identification and the performance (including durability aspects) of products and systems for active and barrier coatings for protection of existing steel reinforcement in concrete structures under repair.EN 1504 Part 8: Quality control and evaluation of conformitySpecifies procedures for quality control and evaluation of conformity, including marking and labelling of products and systems for the protection and repair of concrete according to Parts 2-7 of EN 1504.EN 1504 Part 9: General principles for the use of products and systemsSpecifies basic considerations for specification of protection and repair of plain and reinforced concrete structures with products and systems which are specified in the EN 1504 series or standards or any other relevant EN or European Technical Approval (ETA).EN 1504 Part 10: Site application of products and systems and quality control of the worksGives requirements for substrate condition before and during application including structure stability, storage, the preparation and application of products and systems for the protection and repair of concrete structures including quality control, maintenance, health and safety, and the environment.
