What should be considered concerning the EN 1504 standard?

The European Standard EN 1504 (Products and systems for the protection and repair of concrete structures) is a standard that includes the CE marking of some of its parts; it is divided into 10 parts that cover all the phases of the concrete repair process.

Based on the definitions provided in Part 1, Parts 2 to 10 can be grouped into four groups of documents addressing the same subject. Parts 2 to 7 focus on product specification. They classify materials and propose test methods for their characterisation. These sections are essential for manufacturers to use as a basis to produce their products. In addition, they are also particularly useful for users, as they will serve as a reference to compare products and choose the most suitable product.

Part 8 describes a permanent production control system to be implemented by manufacturers and submitted to an annual audit to maintain quality and assess conformity.

Part 9 is an extremely important document as it sets out the general principles for concrete repair systems, the methods, and explains the process to be followed when repairing or protecting structure.
