Euroclass cable

The requirement to install a Euroclass cable is to be compliant with BS 6701:2016+A1:2017

If you are not installing to this standard then the non-compliance is advised  to be notified to the building owner so that a fire safety report can be undertaken under BS9999 to look at ways to mitigate the risks

What is BS 6701:2016+A1:2017?

This is the British Standard associated with cabling and telecommunications equipment and creates a link from UK Specific electrical installation standards and how they apply to the cabling equivalents

It references telecommunication cables and their reaction to fire performance in regards to CPR (Construction Products Regulation)

“For new installations and the refurbishment or extension of existing installations within the external fire barrier of the building, installation cables which are subject to the CPR shall as a minimum meet the requirements of Euroclass Cca, s1b, d2, a2.”

The Product sheet from the Excel Cabling Brand Manufacturer Highlights these changes and standard – CPR and BS6701:2016+A1:2017 At a glance...

What is CPR?

The ‘Construction Projects Regulation’ aims to break down technical barriers and provide a common technical language to assess the performance of construction products and to harmonise the rules for marketing these products.

Four Key Concepts of CPR:

  • A system of harmonised technical specifications
  • A framework of notified bodies
  • A system of conformity assessment for each product family
  • CE marking of products

Why is LS0H no longer enough?Euroclass Compliant data cabling

Low-smoke, zero-halogen (LS0H) cables were designed to meet three IEC standards:

  1. IEC60332: Flame Spread
  2. IEC60754: Smoke Acidity
  3. IEC61034: Smoke Emission

The CPR applies additional criteria and testing procedures to promote a more harmonised standard to describe a cable’s reaction to ­fire.

Are all cable types required to comply?

  • The CPR applies to all permanently installed cables within a building; communication, power and control cables in fixed installations.
  • There is no distinction between copper and fibre, or shielded and unshielded cables.
  • The only exception is patch leads, which are not within scope of CPR.

So, which CPR Euroclass should you choose?

Different Member States require different CPR classification levels for various applications. Each Member State may implement the standard in line with their regional requirements.

For example, hospitals require a B2ca rating in some countries, but only a Cca rating in others.

To achieve standards compliance in the UK, it is important to choose a cable with a CPR Euroclass of a minimum of Cca, s1b, d2, a2 – as stipulated in BS6701:2016+A1:2017.

This applies to any new installations or the refurbishment and/or extension of existing installations within the external fire barrier of the building.

It is always advisable to always check with a country’s local regulations.
