W hat is the Construction Product Regulation?

Mandatory labelling of all cable products that are permanently installed a civil works. No cable can move on the market without approval to the CPR. All imports cannot cross into Europe without the CE CPR marking Owners of a Brand, automatically become the “Manufacturer” who shall comply with all parts of the Regulation: nothing can be left to a 3rd party BS6701, advisory document for communication cable to the IEE Regulations Code of Practice, clearly states how the new Euroclasses shall be considered. What are the Euroclasses and why are they necessary?

  • European Community writes a Directive for “Construction Products”
  • Construction Product’s Directive accepted “cables” as being part of the

building

  • New CPD test Rig designed to test “long thin things”: an improvement
  • n the 60332-3 rig
  • New Requirements, Total Heat, Heat Release Rate (HR), and

additionally, Smoke and Acid (for the first time)

  • 2013 – made into a Regulation…

Nations shall apply!

  • London Kings Cross Underground Metro station fire 1987
  • Main issues were escape routes and smoke
  • Smoke tests 3m³ (same size as a tunnel) with 60% limit
  • London Borough of Westminster requests only LS cables installed
  • HF – LS material developed

Which essential characteristics of cables are under the CPR?

  • Reaction to fire and (Resistance to fire: not ready yet!)

These support the basic requirements for construction works:

  • Safety in case of fire
  • Hygiene, health and the environment

Which essential characteristics of cables are under the CPR?

  • Reaction to fire, broken down into:

–Heat Release (especially “total”) –Rate of Heat release (important, especially for Fire Fighters) –Flame spread –Smoke (now known as being the main killer) –Why is this an improvement?

I EE W iring Regs ( BS7 6 7 1 ) Every indoor cable should (shall?) meet as a minimum 60332-1-2! However in areas where there is a greater risk: EN 60332-3 Series… (old ladder test with 20Kw flame, only testing for flame spread, which is not necessarily the major contributing factor to the fire!) The actual section of the standard is not made clear…

Previous Regulations I EE Regs?

60332-3 series has “Flame Spread” as a criteria…

  • nly!

60332-3 “series” designed for different cable of outside diameter’s Loading the ladder dependent on OD. Biggest load was 7litres (designed for very large energy cables): to whom some believed was the toughest test! However a small data cable loaded onto the 7litre ladder, even though it fails 60332-1, passes 60332-3!

LOW FI RE-HAZARD CABLES – Saving lives, reducing injuries and preventing dam age Low fire-hazard cables installed in buildings improve fire safety: at home, at the workplace and in public places like hospitals, theatres, airports or train stations. In 1950 the average time from ignition of a fire to flashover was 15

  • minutes. Today, fatal conditions can occur after as little as 3
  • minutes. The most commonly identified cause of death from a fire

incident is being overcome by gas or smoke which accounts for 44% of all deaths. Given these facts, the only possible conclusions are:

  • that the reduction of smoke and effluent gases is relevant to

saving human lives and facilitating the work of rescue teams;

  • that the increased use of plastics in the last 50 years has had a

dramatic effect on escape times

Construction works must be designed and built in such a way that in the event of an outbreak of fire:

  • the generation and spread of fire and smoke within the construction

works are limited

  • the spread of fire to neighboring construction works is limited
  • ccupants can leave the construction works or be rescued by other

means

  • the safety of rescue teams is taken into consideration

CE m arking – no borders…

CE marking – no internal national limits allowed!

  • CPR does not in itself impose requirements on the level of

performance of products.

  • Setting safety levels remains a national responsibility:
  • CPR introduces obligatory Declaration of Performance and CE

marking of cables for construction works with their fire performance

CE m arking cable reaction to fire perform ance

The Product standard – hEN 50575 Scope

  • Electric cables used for supply of electricity and for control and

communication purposes, which are intended for use in construction works and subject to performance requirements on reaction to fire

  • Electric cables includes power, control and communication cables,

including optical fibre cables

  • Note that there is no voltage restriction

CE m arking cable fire perform ance

  • CE marking signifies compliance with applicable legislation and is

passport to the “common” market

  • CE marking already in place under LVD with manufacturer declaration

whereas CPR requires third party intervention even for Class E

  • CE marking under the CPR is possible now (1/ 7/ 16 DoA) the applicable

harmonised product standards are issued and endorsed by EC. Product standard for cable reaction to fire is published: future product standard for resistance to fire is not yet published.

  • Voluntary certification to Euroclasses possible when standards available
  • CE marking should not be affixed unless a DoP has been drawn up
  • For products covered by harmonised standards there are limited

derogations from the need to draw up a DoP (e.g. custom made in response to specific order)

Marking
