Construction Products Regulation (CPR)

The construction products regulation (CPR)

What is CPR?


 CPR stands for “Construction Products Regulation”, which are rules implemented by the European Commission. As it states, CPR rules call for products – including cables – to be tested and certified based on specific criteria before they are used in European buildings. There are six requirements against which products may be assessed. Wire and cable is covered by the 2nd requirement that addresses Safety in the case of fire.

The 2nd requirement describes the safety in case of fire :
The construction works must be designed and built in such a way that in the event of an outbreak of fire:
a) The load-bearing capacity of the construction can be assumed by for a specific period of time
b) The generation and spread of fire and smoke within the construction are limited
c) The spread of fire to neighbouring construction works is limited
d) Occupants can leave the construction works or be rescued by other means
e) The safety of rescue teams is taken into consideration

The CPR prescribes 7 basic requirements for construction work:

1. Mechanical resistance and stability.

2. Safety in case of fire.

3. Hygiene, health and the environment.

4. Safety and accessibility in use.

5. Protection against noise.

6. Energy economy and heat retention.

7. Sustainable use of natural resources.

 

CPR ensures that distributors, consultants, systems integrator, installers and building owners have reliable product information from different manufacturers in different countries to make accurate product comparisons. This will allow for free movement of all construction products within the European Union.

Dop:


The Declaration of Performance is a key part of the Construction Products Regulation. It provides information on the performance of a product. Each construction product covered by a European harmonised standard or for which a European Technical Assessment has been issued needs this Declaration and has to be CE marked. This helps increase transparency and improves the functioning of the Single Market.
