CPR, the European regulation for the construction materials

What is cpr: construction product regulation?

Construction Product Regulation (CPR) is a regulation issued by the European Union with the purpose of regulating the limits of fire resistance and dangerous substances in the materials used in construction.

Construction product regulation

This regulation applies to all products intended to be incorporated, permanently, in construction. It includes not only buildings but also civil engineering works. As far as cables are concerned, the legislation applies to power, telecommunications, data and control cables.


The purpose of CPR is to ensure that all cables used in permanent installations throughout the European Union are assessed, classified and approved under a single criterion.

CPR Classes

CPR includes six new classes, designated from A to F. A implies that the product is non-combustible and F where the fire performance characteristics can not be determined. In this new classification B, C, D and E classes will be mainly used for cables.

Furthermore, there are additional criteria that establish requirements on the amount of smoke produced, the fall of droplets and flamed particles during combustion, and acid content or toxicity of smoke produced.

C= class   |  Ca= cables  |  s= smoke | d= droplets | a= acidity

The official application of CPR comes into force on 1st July 2016. There is a transitional period of one year, during which the entire supply chain must adapt its stock to the new regulations. As of 1st July 2017, all newly installed cables must comply with CPR regulation.


For this reason, it is important that you adapt your supply as soon as possible to cables already designed and tested under CPR criteria. To do this, you must check that the cables are correctly identified, both on the cover and on the identification label, and that the supplier has the corresponding DoP (Declaration of Performance) of the cable.

The DOP (Declaration of Performance) is a document issued by the manufacturer in which all relevant information is recorded: the manufacturer, cable identification, evaluation system used, applicable standard, CPR certification body and performance of the product. This standardized DoP can easily compare products with each other, choosing the right cable for each type of installation.

Declaration of Performance

The CE marking on the product declares that all applicable directives are met.

When you choose Top Cable products, you are guaranteed that you are acquiring cables which fully comply with the requirements established in the new CPR regulations.


Each country can legislate on basic works requirements and the applicable classification, form and different level.

For more information about CPR application criteria in each country, please ask at the Top Cable commercial team.
