Construction Products Regulation (CPR)

FAQ related to LAN Systems


This document reflects the best knowledge of one of the leading expert of the cable industry in Europe and the state of the art at the time of writing (Updated July 2016) based on our understanding of the Construction Product Regulation. It is not a legally binding document and shall in no way be construed or interpreted to give rise to any legal right or obligation whatsoever and is neither a substitute for each stakeholder’s own assessment and decision making. A binding interpretation of Community legislation remains the exclusive competence of the European Court of Justice.

  1. What is CPR – in general?

    Started as a Directive in 1989 (“CPD”) and turned into a Regulation in 2011 (“CPR”) which became applicable from 01st July 2013, the CPR was brought to life by the European Commission to enforce that construction works be designed and executed so as not to endanger the safety of persons, domestic animals or property nor damage the environment.

  2. What is the scope of CPR – in general?

    Products placed on the market for incorporation in a permanent manner in construction works.

    What are “construction works”?

    Buildings or other civil works including tunnels, bridges, metro stations, etc. (no ships, trains, buses, etc.)

  3. What are the goals of CPR?
    • To define harmonised rules for marketing of construction products within the EU.
    • To provide a common technical language to assess performance of construction products.
    • To ensure availability of reliable information to allow comparison of construction products from different manufacturers in different countries.
  4. What are the benefits of CPR?
    • It allows free circulation of construction products in the EU.
    • It enables national authorities to set performance requirements using a harmonised European standard so that users of construction products can better define their performance demands.
    • Market surveillance can rely on one common information structure.
  5. How does CPR affect cables?

    EN 50575 is the harmonised European standard, issued in 2014 and published in the Official Journal of the European Union (OJEU) on 10th July 2015, which specifies requirements for cables used in permanent constructions with regard to their reaction to fire.

  6. What is the scope of CPR – for cables?

    All cables permanently installed in buildings or other civil works.

    Which type of cables?

    All cables, including data- and telecommunication cables.

    All type of conductors, copper and optical fibre.

    What is “permanently”?

    All horizontal and backbone cables are in scope.

    Cable assemblies and patch cords are out of scope.

    Are ships, trains, buses, etc. in the scope of CPR?

    No, these are not civil works.

  7. What does “reaction to fire” mean for cables in CPR?

    The fire performance of cables is classified based on a number of criteria:

    • Flame spread and heat release
    • Smoke production, acidity and flaming droplets

    These criteria and test methods are specified in existing standards IEC/EN 60332-1, IEC/EN 61034-2, IEC/EN 60754-2 and in a new harmonised European standard EN 50399.

    How are the cable performance classes defined?

    • 7 Euroclasses for flame spread and heat release: A, B1, B2, C, D, E and F (A being the most severe i.e. non-combustible and F having no criteria specified)
    • 5 classifications for smoke production: s1, s1a, s1b, s2, s3 (s1a being the most severe and s3 no criteria specified or failing any of the other four classifications)
    • 3 classifications for acidity: a1, a2, a3 (a1 being the most severe and a3 no criteria specified or failing any of the other two classifications)
    • 3 classifications for flaming droplets: d0, d1, d2 (d0 being the most severe and d2 no criteria specified or failing any of the other two classifications)
  8. How are cables assessed and certified to be CPR compliant?

    There are 2 different procedures:

    • System 1+ : to assess Euroclasses B1, B2 and C

      A Notified Body issues an Attestation of Conformity after an initial type test and a factory audit including regular production inspections (2x/year) and audit tests on samples taken from the warehouse (1x/year).

    • System 3 : to assess Euroclasses D and E

      A Notified Body issues an Attestation of Conformity after an initial type test.

  9. What is a Notified Body?

    It is an independent organisation which has been designated by a Member State to carry out conformity assessment according to a directive. It is the obligation of the Member State to notify the European Commission and the other Member States of the designation.

    Which are the Notified Bodies for CPR?

    For the moment there are none. Test labs which are accredited as Notified Body will be listed on the NANDO Information System of the EC website. (Nando = New Approach Notified and Designated Organisations)

  10. Which performance classes need to be used in which buildings/construction works?

    The requirements will depend on various parameters such as the type of building, the level of occupation, the difficulty of evacuation, etc.

    These requirements are not harmonised and therefore may vary from country to country.

    It is the legal obligation of each EU Member State’s government to adopt CPR in national regulation and to guarantee effective surveillance of its market.

  11. Who needs to ensure that cables sold in the EU are compliant with CPR?

    The one who places the product on the market in the EU is responsible to comply with the CPR obligations. This is either the actual manufacturer or the importer.

  12. How can I know whether a cable complies with CPR?
    • The product needs to have a Declaration of Performance (DoP):

      this is a document drawn up by the manufacturer (or importer) in the language(s) required by the EU country where the product is made available and containing defined information such as product identification, its intended use, its declared performance according to CPR and the identification of the Notified Body. The DoP needs to be made publicly available, either on paper or in electronic format. It does not need to accompany the product itself. (see example)

    • The product packaging needs to have defined labelling including CE marking:

      labels on cable drums and boxes need to contain the same data as on the DoP, the reference number of the DoP, the CE mark and the year in which the CE marking was first affixed. The language of the label information can be chosen by the manufacturer (or importer). The cable itself does not need to bear the CE marking nor contain any other of the CPR requirements for labelling. (see example label)

  13. Is the manufacturer solely responsible for CPR compliance?

    No, also Distributors, Specifiers and Building Owners bear responsibilities.

    • Distributors should not resell cables for which there is no DoP and which do not bear the appropriate labelling.
    • Specifiers must reference appropriate Euroclasses and s/a/d criteria according to national CPR regulations.
    • Building owners need to ensure that the infrastructure on their building plans is in line with national CPR regulations.
  14. When does CPR become mandatory?

    As per the publication of EN 50575 in the Official Journal of the European Union (OJEU) on 10th July 2015, the date of application was fixed on 01st December 2015, with a transition period of 12 months. However, due to some minor amendments to EN 50575, the date of application had been postponed to 1st July 2016. Following publication of Amendment 1 to EN 50575 in the OJEU on 10th June 2016  the coexistence period has officially started and will end on 01st July 2017, date when CE marking for CPR becomes mandatory.

  15. Can cables already be CE marked for CPR today?

    With the publication of EN50575:2014+A1:2016  on 10th June 2016 the coexistence period has officially started, meaning that cables can be CE marked since that date.

  16. Are PVC cables doomed to disappear after CPR implementation?

    CPR does not forbid the use of PVC cables.
