The CPR regulation has been a topic of discussion for both installers and security designers for some time. Today we try to clarify, once and for all, the most critical and debated aspects of this rule. In particular we will focus on UE 305/2011 and subsequently on CEI 20-105 v2, dedicated to fire resistant cables.

UE 305/2011

From the original text of article 2 paragraph 1 of the CPR it is clear that it is intended “construction product, any product or kit manufactured and placed on the market to be incorporated permanently in construction works or in parts thereof and whose performance affects the performance of construction works with respect to the basic requirements of the works themselves “.

All cables installed in buildings and civil engineering works subject to fire reaction performance requirements, be they energy or communication or optical fiber therefore, must be classified.

The standard involves all economic operators in the supply chain:

– manufacturer: any natural or legal person who manufactures a construction product or who has such a product designed or manufactured and markets it under his name or brand (Article 11);

– agent: any natural or legal person established in the European Union who has received a written mandate from a manufacturer authorizing him to act on his behalf in relation to certain tasks (Article 12);

– distributor: any natural or legal person in the supply chain, other than the manufacturer or the importer, who makes a construction product available on the market (Article 13);

– importer: any natural or legal person, established in the European Union, who places a construction product from a third country on the European Union market (Article 14).

The subjects involved are required to show:

– the CE marking

– the Declaration of Performance (DoP)

– the system of assessment and verification of constancy of performance (AVCP) – depending on the classification, belonging to a certain class and constancy of performance, must be checked and certified by independent Notified Bodies (eg. IMQ).

The cables are classified into 7 Fire Reaction classes identified by the letters from F to A and by the subscript “ca” (cable) according to their increasing performance. Each class has minimum thresholds for heat release and flame spread. In addition to this main classification, the European authorities have also regulated the use of the following additional parameters:

“A”: acidity that defines the dangerousness of the fumes for people and the corrosiveness for things.

It varies from a1 to a3.

“S”: opacity of the fumes. It varies from s1a to s3.

“D”: dripping of incandescent particles that can spread the fire. It varies from d0 to d2.

Assessment and verification of Constancy of performance (AVCP) must be carried out from class C to class A, including the initial test and factory production control (FPC).

A) Safety in case of fire (Requirement n.2- Annex 1 of the CPR Regulation)
the generation and spread of fire and smoke within them are limited;
the spread of fire to nearby construction works is limited;
the occupants can abandon the construction works or be rescued in any other way;
the safety of the rescue teams is taken into account.
B) Hygiene, health and the environment (Requirement n ° 3 – Annex 1 of the CPR Regulation)

The compliance of the cables with the requirements of hygiene, health and the environment is implicitly considered to be absolved by compliance with the RoHS Directive (2011/65 / EU and subsequent amendments) and the REACH Regulation (1907/2006 / EC).

YES

CEI 20-105 v2

CEI 20-105 v2: Fire resistant cables, flame retardant, halogen free, with nominal voltage 100 / 100V for applications in fixed automatic detection and fire alarm systems.

The standard deals specifically:

4.1 Reaction to fire

4.1.1 Reaction to fire – CPR classification

Taking into account the degree of safety that these cables must guarantee, the cables of this standard must pass the tests required by the fire reaction class Cca-s1b, d1, a1 according to the indications given in the CEI-UNEL 35016 standard. , tests and methods for evaluating the reaction to fire of cables in order to allow classification

according to the Construction Products Regulation are specified by the EN 50575 standard.

6.1 CPR Construction Products Regulation (305/2011)

With regard to safety in the event of fire (Reaction to fire), belonging to a certain class and the consistency of the cable’s performance must be checked and certified by independent Notified Bodies.

Following the issuance by the Notified Body of the Certificate of Constancy of Performance (AVCP) *, the manufacturer must draw up his own “Declaration of Performance” (DoP) in order to be able to place the CE marking.

Below we can see schematically represented the different classes of the relevant legislation and the requirements (main and additional) to be able to fall within them. The diagram also shows the places where the regularly classified product can be installed.

The reference tests for the classification of cables are as follows. Each one of them has its own classification criteria, a possible supplementary system and an AVCP system.

Fca: proof by the manufacturer

Eca: EN60332-1-2

Dca: EN60332-1-2 + EN50399

Cca: EN60332-1-2 + EN50399 / EN61034-2 + EN60754

B2ca: EN60332-1-2 + EN50399 / EN61034-2 + EN60754

B1ca: EN60332-1-2 + EN50399 / EN61034-2 + EN60754

Aca: EN ISO 1716

Each reference standard / test foresees classification limits for the various parameters (dripping, opacity of the fumes, …). Below you can see the main ones:

Example

The wording: Cca s1b d1 a2 indicates:

Cca: a standardized cable in class Cca

s1: smoke production (EN 50399)

TSP1200s ≤ 50 m2

SPR max. ≤ 0.25 m2 / s

b: transmittance ≥60% and <80% (EN 61034-2)

d1: no dripping / particles that persist more than 10s (EN50399)

a2: acidity of gases (EN 60754-2) conductivity <μS / mm pH> 4.3

The ELANFIRE fire resistant cables produced by ELAN fall into class Cca – s1a, d0, a1.

The cables comply with EN50200 PH120 (fire resistant at 850 ° C for 2 hours), with CEI 20-105, UNI 97-95 and CEI 36762.

Below are the fire resistant cables compliant with CPR Cca – s1a, d0, a1:

Cod. 28210 (1) – (5) R – 2×1.00 + SCH.
Cod. 28215 (1) – (5) R – 2X1,50 + SCH.
Cod. 28225 (1) – (5) R – 2X2,50 + SCH.
Cod. 27215 (1) – (5) V – 2X1,50 N-SCH. – EVAC (in the certification phase)
Cod. 27225 (1) – (5) V – 2X2,50 N-SCH. – EVAC (in the certification phase)
