CPR REGULATIONS

In Europe, under the CPR (Construction Products Regulation, EU 305/2011), electrical, control, and communication cables that are permanently installed in construction works must comply with specific fire performance standards.

CPR Cable Classification: Euroclasses

Cables are classified based on their reaction to fire, using a Euroclass system that ranges from the safest products to those posing the highest fire risk.

 
✅ Main Euroclasses for cables




Additional Complementary Classifications


Besides the base Euroclass, additional letters indicate other fire-related characteristics:




 
 
Example:


Cca-s1a,d1,a1 → Cable with:

- Good fire resistance 
- Very low smoke emission 
- Few flaming droplets 
- Low corrosive gas emissions

 
Manufacturer Obligations under CPR


- Classify the cable according to EN 50575 
- Issue a Declaration of Performance (DoP) 
- Apply CE marking with Euroclass and relevant data

 
 
When does CPR apply to cables?

• Applicable to cables permanently installed in:

1. Residential and commercial buildings 
2. Hospitals, schools, airports 
3. Infrastructure works (roads, tunnels, stations)

• Not applicable to:
  1. Loose or portable cables 
  2. Industrial machinery cables not part of the buildings

Additional Recommendations


- s1a: preferred in enclosed areas (less smoke = better evacuation visibility) 
- d1: fewer flaming droplets = reduced fire spread 
- a1: less corrosive gases = lower risk to people and electrical systems
 
What should you consider?

- Some EU countries have stricter national regulations 
- Always check the specific local codes (e.g. CTE in Spain, DIN VDE in Germany)
 
Key Information Needed:

1. - What type of project is it? (residential, office, hospital, industrial, etc.) 
2. - Where will the cable be installed? (indoor, outdoor, in trays, embedded, etc.) 
3. - What type of cable do you need?

  - Power cable (e.g. 750V) 
  - Control cable 
  - Communication/data cable (fiber, twisted pair, etc.) 
  - Halogen-free / flame-retardant 

- In what country or region is the project? (to check local regulations)

With this info, I can recommend:

- The suitable CPR Euroclass 
- Specific cable types (model, type, insulation) 
- Recognized European manufacturers (e.g., Percon)

Perfect! So you're working with Percon, a well-known brand, especially for professional cables for audio, video, data, communications, and audiovisual installations. They have products adapted to the European CPR.

Now that I know you're using Percon cables, here's a specific guide:
