Recognising CPR Compliant Cable Through Labelling

22 October 2018

For all electrical professionals, it is vital to understand and be able to quickly recognise the legal product requirements, as well as the crucial differences between compliant cable and substandard cable.

The new 18th Edition of the wiring regulations has brought changes and amendments to electrical installation across the UK. It is now even more important that we all remind ourselves of this, to be able to make distinctions at first glance.

The most visible way to identify a compliant cable will be the CPR label, which became a legal requirement for cable on 1stJuly 2017.

CPR Labelling

Labelling in relation to CPR for cable is a legal requirement as they are now one of the product categories covered by one, or more of the New Approach Directives. It shows that the manufacturer has designed and tested construction products against they’re reaction to fire. This confirms that it complies with UK legislation.

CPR labels on Prysmian cables are displayed clearly on the packaging to ensure utmost visibility.

We have included an example of a CPR compliant label below, depicting the label with the all-important information for our 6242Y twin and earth cable.

A closer look at a Prysmian CE label

At the far right of the label, you’ll see three boxes, the first of which contains the CE symbols. Immediately next to these there will be the registration number of the notified body that has assessed whether or not the product has met the predetermined standard. This corresponds to the name of the body and the stamp directly opposite, on the other side of the label. In this case, the notified body is BASEC.

Details of the manufacturer, Prysmian UK, the manufacturers address, the registration year follow in the second box down on the right. This is also where you’ll find the Declaration of Performance (DoP) number.

Some parts of the CPR have applied from 2011, however it was extended to cover cables from 1st July 2017. From then on, construction products, including cables, placed on the market in the UK have been required to be CE marked and accompanied by a Declaration of Performance (DoP).

This is a declaration by the manufacturer of the performance of the product in terms of its reaction to fire. When the manufacturer sets a DoP, they take full legal responsibility for its conformity and compliance with the product standard.

Crucially, a CE logo may not be applied to the product unless it meets all requirements of the CPR.

All compliant cables will also show on the label a dated reference to the construction standard applied to the product, which specifies the test required to assess its reaction fire. In the pictured example, this is EN50575: 2014. This is followed by a short description of the product and what it is used for.

There’s no room for doubt- that’s why Professionals Choose Prysmian.
