CE Marking Wire and Cable
In an earlier post, I wrote about the requirements for CE Marking wire and cable and discussed the <HAR> mark. In 2016, the Construction Products Regulation 305/2011 (CPR) came into effect, replacing the Construction Products Directive 89/106/EEC. The CPR included provisions covering any kind of materials that could be used in construction, and that includes electrical cables.
A New Standard under the CPR
A new standard was approved, EN 50575, covering the characteristics of power, control and communication cables used in permanent installations in buildings. EN 50575 covers the reaction of cables to fire. The standard provides requirements for four characteristics: flame spread, smoke generation, the formation of molten droplets and acid content. The result is a new set of markings for cables covered by the standard, including CE Marking. Also required by the CPR is a Declaration of Performance, not a Declaration of Conformity. The Declaration of Performance provides different information than that found in a Declaration of Conformity and they are NOT interchangeable.
Application of EN 50575
EN 50575 only applies to cables or wiring products intended for use in construction. It should not be applied to wiring materials used for internal wiring of appliances and products. These products are outside the scope of the CPR and therefore are also outside the scope of EN 50575.
- Cables used for permanent installation in buildings must be CE Marked starting 1-Jul-2017
- Wire and cable products used in machines and appliances are not affected by EN 50575, and therefore should not be CE Marked
- Cables used to interconnect machinery and which are permanently installed into building infrastructure (e.g., Ethernet cables and other interconnecting cables run through building structures in permanent wireways or in plenum spaces) require CE Marking as of 1-Jul-17
- Wire and cable products, like line-cord assemblies, for example, require a CE Mark because they are complete products and are covered by a specific EN Standard under the Low Voltage Directive.
Here’s a good summary of the new requirements and an explanation of the new markings in a video by General Cable. Full disclosure: we have no relationship with General Cable or any other wire and cable manufacturer.
