The Construction Products Regulation (CPR) states the harmonised requirements for construction products thought out the EU, allowing consumers to easily compare the performance of different manufacturers products.
From 1st July, 2017, the Construction Products Regulation became a legal requirement for cables permanently installed in buildings and construction works.
Before placing any cable on the market, the manufacturer is legally obliged to have the product tested by a third party ‘Notified Body’ laboratory for the Reaction To Fire requirements specified in the European Standard EN 50575.
The Reaction To Fire has seven classifications:
- Class A – incombustible products such as bare copper mineral insulated cable
- Class B1 – virtually incombustible low smoke zero halogen cable
- Class B2 & C – low smoke zero halogen cable types
- Class D – low smoke zero halogen and some PVC products
- Class E – PVC, chlorinated rubber and other non-flame propagating types
- Class F – PE sheathed and other flammable sheathed cables
The majority of low smoke zero halogen cables meet the requirements of Class B2, C and D, whilst PVC cables meet Class E.
The manufacturer must issue a ‘Declaration Of Performance’ (DoP) identifying the product, stating the Reaction To Fire classification and the intended use. The product label must also include this information and the CE mark to confirm compliance to CPR regulations.
It is important to note that not all cables used in buildings and construction are subject to the CPR requirements. For example most flexible rubber cables, welding cables and coil leads types are excluded from the CPR regulations.
Fire resisting cables, designed to provide continuous operation in the event of a fire, are also currently excluded from the CPR regulations until the appropriate Harmonised Standard is published.
