Construction Products Regulation (CPR)

Posted on 12 July 2021

As a manufacturer of professional cabling, we feel responsible to provide cabling you can rely on every day. That’s why we chose to offer CPR certified cabling with maximum fire safety. In the case of a fire, most casualties are a result of toxic smoke. By providing cabling which nearly eliminates toxic smoke and in addition ceases the fire from spreading, we hope to contribute to a safer future.

What is CPR?

The Construction Products Regulation (CPR) is an EU regulation for installation cables, classifying cables based on their fire performance. It is aimed to improve fire safety in buildings.

Why CPR?

In the case of a fire, the biggest danger is toxic smoke. Since buildings are filled with cabling, the risk of spreading fire is very big. To improve the overall fire safety, the installed cables have to be within a certain standard, the new CPR cabling will resist the spreading of fire while minimizing toxic gasses released.

Which CPR class cable do I need for my project?

The CPR cable standards are harmonized throughout Europe. However, Every country makes its own regulations regarding which CPR class cabling has to be used in different types of buildings. To know which CPR class cabling you need, please check your local norms.

3 additional types of criteria

Smoke concentration

These classes of smoke production clarify the amount of smoke released in case of fire.

(s1, s1a, s1b, s2 and s3)

Burning droplets

These classes indicate the amount of burning droplets.

(d0, d1 and d2)

Acidity of the smoke

These classes indicate the amount of acidity in the smoke.

(a1, a2 and a3)

What do the different classes mean?

Although CPR classes range from Aca to Fca, in reality very few cables will reach the Aca and B1ca standards. In reality, only cabling from classes B2ca, Cca, Dca and Eca will be used in buildings. With B2ca being the highest class, providing the best fire performance, and Eca being the lowest class providing limited fire performance.

Additional levels of classification:

› s: The amount of smoke emitted

› d: Flaming droplets and particles

› a: Acidity of the smoke

Euroclasses are classes of CPR cabling, every class has its specific requirements by which the cabling needs to be tested. The Euroclass table shows every class with its specific properties regarding fire performance.
