Enormous efforts have been undertaken to improve the standards and recommendations surrounding protection and repair of concrete structures across the European Community. Each individual E. C. member has formerly used it’s own or utilised and modified standards from other sources. This has led to confusion and misinterpretation of methods and practices. It has also meant that direct comparisons of procedures, product performance and specification have not been possible.
Now after several years of intense activity the new European Standard EN 1504 has been produced and is set to replace existing individual national standards throughout Europe within two to three years.
Essentially the new European Standard EN 1504 comprises of 10 main standards and approximately 65 standards for test methods.
|EN 1504 Part 1||Definitions|
|EN 1504 Part 2-7||Products|
2 Surface protection for concrete
3 Repair mortars, structural and non structural
4 Structural bonding materials
5 Concrete injection materials
6 Anchoring of reinforcing steel bar
7 Reinforcement corrosion protection
|EN 1504 Part 8|
Quality control and evaluation of conformity
|EN 1504 Part 9||General principles for use the use of products and systems|
|EN 1504 Part 10||Site application of products and systems and quality control of the works|
In addition approximately 65 standards offer test methods for the assessment of concrete protection and repair systems allowing direct comparison of product performance from all manufacturers.
At the time of this posting it is claimed that the EMACO NANOCRETE range of concrete repair mortars produced by BASF Construction Chemicals (UK) Ltd is the only system to meet the requirements of the European Standard EN1504 Part 3
