interim phase


– Council Directive 89/106/EEC of December 21, 1988 of the Council of the

European Communities

– The ‘Construction Products Directive’ aims to ensure the free movement of all

construction products within the Union by introducing a common technical

language, consisting of harmonized standards and European technical

approvals, in which manufacturers can express the performance of the products

that they place on the market.

European directive CPD is/was:

- mandatory for the target

- with implementation in national legislation and acts of member state

- CPD not covers:

- standards for test-procedures of cables and cable management

systems (National Standards are valid)


Construction Products Regulation (CPR)

The CPR published 9th March 2011 become mandatory law, after the interim

phase, at 1st July 2013 for all Member States and replaces the CPD

- European Regulation CPR is:

- a mandatory law

- needs adaptions in national legislation and acts

The ‘Construction Products Regulation’ aims also to ensure the free movement of

all construction products within the Union by introducing a common technical

language, consisting of harmonized standards and European technical approvals,

in which manufacturers can express the performance of the products that they

place on the market.


Construction Products Regulation (CPR)

- CPR covers for the first time for Power, Control and Communication

Cables:

- standards for test-procedures of cables and cable management

systems (CMS Standard in preparation)

- Notified Bodies (independent test centre), which have to be defined

by the member state

- Legally responsibility of Manufacturer to provide an EU conformity

declaration for cables

- the CE-marking of cables

- All cables installed in construction works need to be tested


CPD/CPR – Requirements for products

In accordance with the CPD/CPR, just products are allowed to be placed on

market, which fulfill specific requirements.

For following categories, requirements are are taken into consideration:

- Mechanical strength

- Fire safety

- Hygienics, health and environment protection

- Safe usage

- Acoustic protection

- Energy saving and thermal protection


CPD/CPR – Requirements Fire Safety

ESSENTIAL REQUIREMENTS – Fire Safety in case of fire

The construction works must be designed and built in such a way that in the

event of an outbreak of fire:

– the load-bearing capacity of the construction can be assumed for a specific

period of time,

– the generation, spread of fire and smoke within the works are limited,

– the spread of the fire to neighbor construction works is limited,

– occupants can leave the works or be rescued by other means.

– the safety of rescue teams is taken into consideration.

In Mai 2009 the European Commission assigned CENELEC with a

Mandate to develope harmonized Standards

The assigned Mandate M/443 contains in general:

Harmonized Standards for

Reaction to fire

Restistance to fire


Commission – Reaction to fire


Definition of Reaction to fire:

Response of a test specimen when it is exposed to fire under specified

conditions in a fire test. (ISO 13943)

Reaction to fire shows the influence to burning sample cables. Cable samples

are burned to test the the spread of flames, the emission of smoke and

release of flaming droplets/particles and acidity. Heat release and flame

spread are the main classification criterion, but smoke production, flaming

droplets and acidity are also classified.

Seven different classes (Aca, B1ca, B2ca, Cca, Dca, Eca, and Fca) are defined for

cables.

Test method:

On a vertical ledder (3.5m) mounted cable samples are burnded by a 20.5kw

(B2ca, Cca and Dca) or 30kw (B1ca) flame source in a furnace chamber (based

on EN 60332-3).

While test sensors analyzing the temperatur, ammount of oxygen and

emissions of carbon dioxid of the combusting gases. This gives information

about heat generation. Furthermore a light sensor, mounted in the exhaust

pipe, analyzes the smoke production. Flaming doplets/particles are

observerd while the 20 minutes of test.

Commission – Resitance to fire


Definition of Resistance to fire:

Ability of a test specimen to withstand fire or give protection from it for a period

of time. (ISO 13943)

Resistance to fire performance shows how long a cable will operate in case of

fire.

CPD/CPR – Currently relevant Standards – Reaction to

fire


Methods to test the functionality of cables in the event of fire

– Insulation integrity according to:

IEC 60331 (FE)

EN 50200 (PH)+Annex E

EN 50362 (PH)

BS 8434

BS 6387 (CWZ)

– Functional integrity according to:

DIN 4102-12 (E)

Important: FE ≠ E

FE = Flame impact; E = Electrical cabling system

Characteristic:

Fire resistance

Characteristic:

Functional integrity (E)

CPD/CPR – Currently relevant Standards – Reaction to

fire – test of cable

prEN 50577 Electric cables - Fire resistance test for unprotected electric cables

(P classification) estimate availability of standard 2015

– This European Standard specifies a test method to evaluate the maintenance of

circuit integrity of electric cables which have intrinsic resistance to fire under fire

conditions, in order to classify the electric cable according to EN 13501-3

– Test Furnace: 3 m long; 2 m deep; 2,5 m high.

– Cables will be tested in a standardized representative installation (Cable

management system) on perforated trays and perforated suspension supports

– The Resistance to fire performance is indicated in terms of survival time.

– The classifications are 15, 30, 60, 90 and 120 minutes of operation in a

standardized fire condition.

– P 15, 30, 60, 90, 120 for electrical and fibre-optic cables and accessories


New

– The CPR repeals the CPD at 1st. of July 2013.

– Until July the required standards, definition of notified Bodys and

Testlaboratories for all memberstates will be prepared.

– Cables tested according the new european standards for reaction to fire, will

and have to be available at date of change.

– Available also will be the national classifcation for use of tested cables in

standard and fire safety installations.

– Not available will be the P-classification standard. (Expected Year 2015)

– Not available will be the national adaption of fire regulations and building codes.

CPD/CPR: Current Situation - Consequences for

engineers, Installer, distributors


Finally, after more than 20 years since the publication of the first EU Directive, the

standard definition comes near to the final realization phase.

Without clarified and implemented adaptions in existing building codes, the

existing cable types, tested according CPR can be purchased but not

installed according CPR until all required standards are published.

Installations will be done according valid fire regulations and national

building codes with existing tested and approved cable and cable fixing

systems.

CPD/CPR: Conclusion


CPD/CPR: Dätwyler your Partner now and for the future

Because of the extensive and long experience in the safety cabling development

and installation according to the German standard,

Membership in Working Groups of CENELEC Standardization,

invest in future-oriented Laboratory- and Production-Equipment

and at least high-quality cables,

Dätwyler will be your most adequate partner to face the new and future

challenges.
