CPR
(EN: Construction Products Regulation) is a term related to Regulation (EU) No 305/2011 of the 9th of March, 2011 regarding construction products.
CPR relates to "any product or kit which is produced and placed on the market for incorporation in a permanent manner in construction works or parts thereof and the performance of which has an effect on the performance of the construction works with respect to the basic requirements for construction works". In other words, it refers to all construction products that have a direct influence on construction works and safety of their users.
CPR requirements refer to EN 50575 and describe classification methods. European norm gained Polish status (PN-EN
50575).
The basic aim of CPR is to define reaction to fire (cable performance under fire conditions) of the given product. Cable performance in the event of fire is of top importance as it influences fire spread in the buliding and determines its effect as well as fire safety to a large extent.
New EU Directive comes into force on the 1st of July, 2017. Transitional period started one year before so each EU country had time to adjust its products to new regulation and have all the items being subject to new regulations tested by proper certifying bodies.
EN 13501-6 standard specifies - in greater details - the number of parameters having influence on cable performance in the event of fire, such as e.g. heat release, smoke production, its acidity and conductivity. Having the cables tested against the aforementioned parameters, their reaction to fire can be determined.
PN-EN 50575 standard refers to all cables and wires, installed in buildings and being a part of their installations, used for electricity and communication including cables with fibre optics. The aforementioned standard does not refer to signalling and power cables that assure power supply or control under fire conditions.
Signalling or power cables that assure power supply or control under fire conditions are not subject to PN-EN 50575 standard therefore are not covered by CPR at the moment. In case of these cables all previous rules of admittance are still binding, what means that FE180/E90/PH90 cables should have technical assessments and proper certificates.
DoP
(EN: Declaration of Performance) or DWU (PL; Deklaracja Właściwości
Użytkowych) is a document drawn up by the manufacturer and confirming reaction to fire of the given product.
