Reaction to fire on CPR cables


 CPR European regulations prescribe severe fire tests to be performed by cable manufacturers in official laboratories. Official results of these tests indicate the performance of these cables before the fire, reflected in class B2ca, Cca, Dca or Eca).

The regulation of  Construction Products Regulation (CPR), in force since July 1st, 2016, requires cable manufacturers, distributors, project managers, architects, builders and installers across Europe to provide cables with the correct CPR classification in construction buildings.

European CPR regulations prescribe severe fire tests to be performed by cable manufacturers in official laboratories. Official results of these tests indicate the performance of these cables before the fire, reflected in class B2ca, Cca, Dca or Eca.

During fire tests, the heat release and flame propagation are measured on a constant basis. CPR laboratory fire tests follow these reaction to fire parameters:

  • Standard: EN 50399
  • Cabin Fire
  • Vertical cable ladder
  • Gas Analyzers
  • Fire burner 20 kW
  • Heat release rate
  • No flame spread
  • Smoke production
  • Falling particles

No fire propagation

Among many other relevant aspects, cables B2ca should not propagate the fire to more than 1,5 meters. The cable Cca They should not spread the fire over 2 meters. Therefore, the installation of cables B2ca or Cca prevents a localized fire from spreading to other areas through the cable network.

Additional classification levels

In addition, the CPR provide three additional levels of classification:

  1. The amount of smoke produced, indicated by the following rankings s1a, s1b, s3 or s2.
  2. Combustible particles falling during the cable combustion, indicated by d0, d1 and d2.
  3. The acidity level of the smoke produced during the combustion, classified as a1, a2 and a3.

These additional classifications are vital when it comes to safety in case of fire.

What CPR classification is required in all European countries?

National regulations prescribe specific classes based on the environment and installation rules.

In most European countries class Cca is required in public places with high density if people and important equipment such as: offices, schools, hotels, hospitals and suchlike.
