CPR Introduction

 

 

 

 

3. Relevant Euro Classes for different Environments & EU countries.

 

 

The regulation assigns seven (7) “EuroClass/reaction to fire” levels, ranging from ‘Aca’ to ‘Fca’  The CPR ranking highest to lowest are: Aca; B1ca; B2ca; Cca; Dca; Eca and Fca. The ‘ca’ tag     on the letter indicates cable. Classes are listed from the most stringent ‘A’,  non-combustible, to   ‘F’. For telecommunication cables, the best performance you’re likely to see is B2ca. Typically, EuroClasses are assigned based on the application space/structure type. Structures with a high density of people (public spaces) or limited evacuation routes (hospitals/high rise) may specify       a higher rated classification e.g. hospitals may be rated as B2ca or Cca; commercial properties may be Cca or Dca; while a single family dwelling may be Dca or Eca. This varies from country to country and even within country regions.

Euroclass Level Description Environments
B2ca

 

Very High fire protection (self-extinguishing)

High density of people or individuals with limited mobility (Fire exits in public building,
Airports and Hospitals)

Cca

High Fire protection
(self-extinguishing)

Medium density of people
(Public buildings, schools, hotels, and office buildings)

Dca

Moderate Fire Protection
(Limited emissions)

In some regions this is used a
minimum cable requirement.

Eca

Basic Fire Protection

In some regions this is used a
minimum cable requirement.

 

CPR is mandatory for all European countries, but the minimum CPR requirements may vary from country to country. Some countries have implemented a minimum classification and some countries have adopted a risk assessment methodology based on the type of installation or its fire suppression system.

Different classes require different criteria to be applied. Therefore, cables will be made and tested to achieve the requirements of a particular class. It is not just the way they’re made and tested, it involves who tested them and how the manufacturing process is controlled. Cable cannot simply “jump up class” by tweaking the manufacturing or doing some more tests. Class B1ca cable could be sold as Class Cca (as Class B1ca is superior to Class Cca), but Class Cca cannot be sold as.

Class B1ca.
