CPR Info

Common classification of fire properties

Cables were not previously included in the CPR, but since 2017 cables are part of this EU common building standard. Formally, the cable regulations are termed EN 50575. But for simplicity, we call them CPR.

The CPR for cables specifically covers fire classification and test methods for cables used in buildings.

What is the CPR?

The European Construction Product Regulation (CPR) aims to ensure reliable information on the performance of products used in buildings such as floors, ceilings and facings. This is achieved by harmonising the rules for how construction products are tested and classified. Anyone who wants to introduce a construction product to the market must test, classify and label the product in accordance with the EU-wide rules in the CPR.

Tested and Approved for Safer Installations

A common EU standard for fire safety in cables was introduced in 2017. At NKT, we have been striving to make the standard more easily understood. This makes the implementation of the regulations easier for both our customers and ourselves.

Cables You Can Trust

NKT was early in developing a solid knowledge about CPR and the fire classes and converting a wide range of cables in accordance with the regulations.

When you choose products from NKT, you can be sure that you are getting the highest quality cables that meet all the requirements in accordance with the EU common directives within CPR.

The materials that we use in our products are tested and validated at our own laboratories, in different countries, and under the control of third parties. The laboratories have the capacity and expertise to carry out comprehensive fire and material property tests, thus satisfying the CPR requirements. In addition to the development of new materials, we continuously test our existing products’ properties to ensure that we are offering world-class cables.

Halogen-free is not a requirement under the CPR. But when we talk about fire safety, the most important difference between a halogen-free cable and a cable with PVC is that the halogen-free cables produce significantly fewer harmful substances and less fumes when they burn. Since smoke production and the spread of poisonous particles are two of the criteria in the CPR standard, halogen-free cables have a greater chance of satisfying the requirements.
