What is CPR?
CPR -Construction Products Regulation
(305/2011 – Directive 89/106CEE) .
This regulation establishes the basic requirements that all products to be used in construction have to meet in the European Union. The CPR specifies seven basic safety requirements that must be met, one of which is safety in fires that directly affect cables.
The CPR must be met by all market players (public administration, manufacturers, retailers, users, etc.) in the European Union. The fundamental standard for the application of the CPR is the EN 50575. The requirements in fire are divided into EUROCLASSES.
Each country defines what Euroclass each cable must comply with depending on its legislation. In Spain, it is defined in the adaptation of the REBT (Low Voltage Electrotechnical Regulation), RSCIEI (Industrial Facility).
The CPR defines a construction product as all those which will be permanently included in construction and civil engineering works.
All those connection cables, feed-in, control, and switching panels, and a terminal, device, and/or machine’s internal cables are excluded. Cables for elevators, service lifts, tow trucks, cable tray chains, swinging arms, robots, etc. or any cable designed specifically to be used in industrial processes.
The standard EN 50575 is the basic standard to apply the CPR. This standard defines all of the administrative and legislative aspects necessary for the manufacturer to demonstrate compliance with the requirements and to market their products. This standard includes three basic aspects for the manufacturer to demonstrate compliance with the standard:
EVCP (Assessment and Verification of Constancy of Performance)
The cable’s compliance with the manufacturer-stated performance must be demonstrated through assessing and verifying constancy of performance. The manufacturer should always maintain overall control and all the means necessary to assume responsibility for the product’s compliance.
DoP (Declaration of Performance)
The manufacturer must draw up a Declaration of Performance (DoP). This document identifies the product, what it is to be used for, and the cable’s performance in relation to fire safety and the emission of hazardous substances (for the time being they are not assessed since there is no harmonized technical specification). The DoP provides full and documented traceability that all processes and materials used comply with the regulation.
CE (EC marking)
The EC marking symbol should be placed visibly, legibly, and permanently on boxes, coiling, retractable items, etc. The marking’s symbol should not be on the cable’s covering.
What are the Euroclasses and additional classification?
The cables are classified by their performance in terms of their reaction to fire and the emission of hazardous substances. The European Union has created a common language to define cable fire reaction performance. For this reason Euroclasses and additional classifications have been defined.
