PROCAB Contractor Series

PROCAB Contractor Series

The contractor series range is intended to be used in applications where CPR classification EN50575 is required. This way you provide the safest possible solution to installed cabling.

These especially designed cables provide optimal, tested safety in every environment. They are tailor-made to minimize any hazardous smoke, burning droplets and acidity in the smoke. The outer jacked is flame retardant, providing optimal resistance to spreading fire and therefore maximizing the overall safety of the construction and building. Available Euroclass types include B2CA, CCA and DCA.

CONSTRUCTION PRODUCTS REGULATION CERTIFIED (CPR)

CPR Compliant EN50575As 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 case of a fire, most casualties are a result of the toxic smokes.

By providing cabling which nearly eliminates toxic smokes and in addition ceases the fire from spreading, we hope to contribute to a safer future.

Procab,

Your CPR certified partner.

 

WHAT IS CPR AND WHY USE IT?

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

In case of a fire, the biggest danger is the 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.

GOALS OF CPR AND RESPONSIBILITIES OF THE MANUFACTURER

The construction product regulation has three main goals:

  • Guarantee higher safety levels for fire and dangerous substances
  • Ensure harmonization across the European union
  • Provide greater clarity and traceability

After the initial test to determine which CPR class corresponds with the cables fire performance, the manufacturer is required to consistently carry out follow-up tests by the Notifying Laboratory.

The manufacturer is obligated to provide a Declaration of Performance for all available cables wherein all information regarding the manufacturer, cable identification, applicable standard, certifying organism and CPR performance can be found.

WHICH CPR CLASS CABLE DO I NEED FOR MY PROJECT?

The CPR cable standards are harmonized throughout Europe. However, Every country makes it's 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.

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 it's specific requirements by which the cabling needs to be tested. The Euroclass table shows every class with its specific properties regarding the fire performance.

3 TYPES OF ADDITIONAL CRITERIA

CPR Smoke concentration

SMOKE CONCENTRATION

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

  • s1: very little smoke production
  • s1a: s1 with visibility over 80%
  • s1b: s1 with visibility ranging from 60% to 80%
  • s2: intermediate smoke production
  • s3: Neither s1 or s2

BURNING DROPLETS

These classes indicate the amount of burning droplets.

  • d0: no falling droplets
  • d1: burning droplets persist less than 10ms
  • d2: neither d0 or d1
CPR Burning Droplets
CPR Acidity of smoke

ACIDITY OF THE SMOKE

These classes indicate the amount of acidity in the smoke.

  • a1: Low acidity  (UNE-EN 60754-2 conductivity <2,5ms/mm y pH > 4.3)
  • a2: Intermediate values of acid (UNE-EN 60754-2 conductivity <10 ms/mm y pH > 4.3)
  • a3: neither a1 or a2
