Reaction to Fire Requirements for Cables under the Construction Products Regulation 7 th June2017 Dr. Jeremy Hodge Chief Executive Summary New fire requirements applied to all permanently installed cables Cables will be CE marked to the CPR
SLIDE 2
SLIDE 3
The Construction Products Regulation (CPR)
EU Regulation 305/2011 - harmonised conditions for the marketing
- f construction products
Applicable for all building products, including cables, made available
- r offered to the market place for permanent installation in buildings
and civil engineering projects
Domestic dwellings Industrial buildings – Factories, warehousing Offices Shops and out of town outlets Hospitals and care homes Entertainment and sports facilities/stadia
Common approach for testing and certification of all construction products

Scope of CPR for Cables – EN 50575+A1
New requirement for cables across EU and applicable to all power, control and communication cables Fire performance – for Reaction to Fire only at this stage Cables with declared ‘Fire resistance’ / circuit integrity are not eligible for classification under the Reaction to Fire CPR Provides a consistent process to quantify Reaction to Fire characteristics:
heat release flame spread smoke and acid gas emission
UK – only affects selling of cables, not use Allows end-users to make better informed cable choices
SLIDE 5
Launch of CPR for Cables
Date of Applicability was 10 June 2016
Declaration of Performance and CE marking become optional Cables manufactured before this date could not be CE marked
End of co-existence period is 1 July 2017
Declaration of Performance and CE marking become mandatory CE marked cables will be available to the market before this date and should be stocked
Limited time to obtain CE marking - shortage of testing capacity Implementation will vary by Member State
National standards and requirements will be replaced by CPR No UK regulatory requirements for particular classes but cables shall be CE marked. Likely to be driven by specifiers and insurers
SLIDE 6
Manufacturer / Supplier Responsibilities
Decide upon cables/ranges for evaluation and anticipated class Commission Notified Body work as appropriate CE marking and labeling Publication of Declaration of Performance and retention of data for 10 years Technical documentation Factory production control Factory sample testing including annual fire testing Traceability requirements Safety / installation instructions in local language of use Records of complaints and recalls – retention etc.

SLIDE 7
Distributor/Importer Responsibilities
Only compliant product to be placed on the market Ensure AVCP undertaken, technical documentation and Declaration
- f Performance have been prepared by the manufacturer
Check product is CE marked Recall product where relevant, record of complaints Safety info / contact details of importer supplied with product Local language of use Storage and transportation without degradation Co-operate with national authorities Importers shall undertake routine testing

SLIDE 8
Supply Chain
‘Making available on the market’ means offer or supply No get-out for OEM cables supplier to user Economic operators (manufacturers, authorised representatives, importers, distributors) are obliged to tell market surveillance authorities:
Where they have obtained supply of product from To whom they have supplied product
Applies for 10 year period No distinction between distributor and wholesaler
7
SLIDE 9
End-user’s Responsibilities
No formal responsibilities under CPR Shall comply with National Regulation and/or local codes Comply with all Health & Safety requirements Have realistic expectation for cable performance Purchase CE marked cables with traceable provenance Co-operate with national authorities Sample testing
8
SLIDE 10
Manufacturer Duties of Importers / Distributors
If using own trade name or trademark on the cable then the Importer/Distributor assumes the responsibilities of the manufacturer Modifications to product will require the distributor to assume manufacturer responsibilities, for example:
Overjacketing / oversheathing / overbraiding Additional marking / metre marking Repackaging – reeling, coiling, cut-to-length – information flow still needed by economic operator

SLIDE 11
Simplified Procedures
A ‘manufacturer’ may use the results of obtained by another manufacturer (OEM) for their Declaration providing:
The ‘manufacturer’ obtains permission from the OEM to use the data The OEM remains responsible for the accuracy, reliability and stability of the results
OEM data can be used to generate Distributor Classification Reports to support Distributor DoP

Class Predictions
Class Aca – Very few cables with this classification (glass tape/mineral insulated) Class B1ca – Highest performing cables only (limited requirement) Class B2ca – Commonly used class for many LSHF cables Class Cca – Commonly used class for many LSHF cables Class Dca – Lower performing LSHF cables/higher performing PVC – System 3 so less costly Class Eca – Many common PVC and other cables which have no additional claims of fire or smoke performance - Entry-level test Class Fca – Cables not usable in many applications

Application of CPR
Usage requirements by will vary by European country
National standards and requirements will be replaced by CPR No UK regulatory requirements for particular classes. Likely to be driven by specifiers and insurers
Transport for London S1085 – Fire safety performance of materials
Stations and tunnel infrastructure - Cca-s1a,d0,a3
Commission Regulation 1303/2014 – Safety of railways in tunnels
Tunnels >1km – B2ca-s1a,a1
Risk based approach to performance
High risk (lots of people or impaired means of escape for example hospitals, concert halls, high rise buildings) = Class B2ca Medium risk (lower number of people or large open areas for example industrial
- r low rise buildings) = Class Cca/Dca
Low risk (for example domestic dwellings) = Eca
21
SLIDE 23
Observations
Manufacturers are being over optimistic of cable’s performance Bundled cable arrays performing less well than single spaced arrays Performance within a defined family can vary widely Significant increase in Class Eca testing as 1st July 2017 approaches Significant lack of awareness and understanding over regulation, end user expectation and cable performance available Applicability of ‘permanent installation’ for utility supply cables?
Penetration length into buildings and structures

Frequently asked questions
Will there be an extention to the Period of Co-existence What cables are included in the CPR What is a ‘building’ What is meant by ‘permanently installed’ Indoor/outdoor cables What is meant by placing ‘on the market’ and at what point does it become ‘on the market’ Role of Authorised Representatives Sale of old stock Retrospective CE marking Distributors can declare different performance from OEM so long as the type testing/Classification Report supports this Dual sourcing Do labels have to be applied to every cut length
