9: What does the EC marking look like?

cpr-marcado-ceThe EC marking symbol must be fixed in a visible, legible and indelible manner on the packaging used to market the cables, and it must be accompanied by additional information that is indicated in the harmonised standard. It is not compulsory for the marking to appear on the cable.

Example of tagging with EC marking for a class Cca cable, is:

 
  1. Manufacturer’s name and registered address, or identification mark.
  2. Unique identification code of the standard product.
  3. Fire reaction performance class
  4. European standard applied as it is named in the Official Journal of the European Union (OJEU).
  5. CE marking.
  6. The last two digits of the year when the marking was made for the first time
  7. Identification of the Notified Body (0099 corresponds to AENOR).
  8. Identifying symbol of Cables RCT products with CPR classification.
  9. Reference number of the Declaration of Performance (DoP).
  10. Use foreseen for the product as indicated in the applied European standard.

Which standards are applicable for the CPR?

UNE-EN 13501-6

Fire classification of construction products and building elements. Part 6: Classification using data obtained from reaction to fire tests on electric cables.

UNE-EN 50575

Power, control and communication cables. Cables for general applications in construction works subject to reaction to fire requirements.

UNE-CLC/TS 50576

Electric cables. Extended application of test results.

UNE-EN 50399

Common test methods for cables under fire. Heat release and smoke production measurement on cables during flame spread test. Test apparatus, procedures, results.

UNE-EN 60332-1-2

Test methods on electric and optical fibre cables under fire conditions. Part 1-2: Test for vertical flame propagation for a single insulated wire or cable. Procedure for 1 kW premixed flame.

UNE-EN 61034-2

Measurement of smoke density of electric cables burning under defined conditions. Part 2: Test procedure and requirements.

UNE-EN 60754-2

Tests on gases evolved during combustion of materials from cables. Part 2: Determination of acidity (by pH measurement) and conductivity.

Will the CPR will be applied equally in Europe?

The spirit with which the CPR has been created is to combine criteria in the whole of Europe and therefore it should be applied equally in any country. Each Member State has the criterion just to decide on which of the Euroclasses will be applied to a specific product in that country.

The measurement and assessment criteria will therefore be equal in each country but different Euroclasses may be established for the same product in different countries.

Will the CPR bring about important modification in cables?

Yes, as the assessment criteria of the CPR are more demanding than current criteria and thus will require the variation and readjustment of compounds and parameters which will make the cables be very different, even though their name does not change. The Euroclass must be marked on the sheath of the cable.
