New Construction Products Regulations (CPR)

With the spread of fire within buildings being at the top of everyone’s agenda at the moment (and rightly so) due to the horrific events in London recently, we thought we would try to clarify and inform our customers about the new Construction Products Regulation (CPR).

The Construction Products Regulation (CPR) is now a legal requirement it is important to our customers to make sure you understand the impact on electrical cable and how it will affect you.

From 1st July 2017, most cables designed for permanent use within domestic, residential and commercial buildings will be subject to the Construction Products Regulation. The regulation will enable designers, specifiers and installers to assess the contribution that cables make to the spread of fire within a building.

Affected cables can be classified into one of seven classes, Aca – Fca. Realistically, only five of the classes will apply to cables.

Many data and control cables, through their design, will only meet the requirements of either ‘Fca’ or ‘Eca’. However, CPR alone does not imply any Low Smoke Halogen Free (LSHF) properties – many PVC cables can comply with Class Eca or even Cca. If you need an LSHF or LSZH cable, make sure to specify this as PVC-based “LSF” cables will give off large amounts of toxic gases and fumes compared to LSHF.

As part of Andrews Electrical Ltd commitment to meeting current regulations, we only source cable from reputable British well-known brands that meet these regulations, such as, Prysmian, Doncaster & Copper cable Co Ltd.

Andrews Electrical Ltd can install many’ of CPR-compliant products from our stock including:

– Alternative to Belden cables

– Structure wiring cables including Cat 5E, Cat 6, Cat 6A

– Coaxial cables

– Signal & control cables

– Fibre optic cables

– Power cables

Make sure your Electrical Cable Installations are compliant; if you are unsure you should ask for a Declaration of Performance (DoP) from the cable manufacturer. This document shows critical information such as manufacturer’s name, product type and the class met. By law, anyone selling CPR-compliant cable products has to keep records of products and batches sold and all DoP documents have to be kept for up to 10 years after the date of sale.

Hope this information helps, be safe.
