Fire resistance tests for service installations - Part 11: Fire protective systems for cable systems and associated components

This European Standard describes the method to evaluate the performance of protective systems for electrical cable and busbar systems in order to maintain the circuit integrity under fire conditions to classify the protective system according to EN 13501 3 for the P classification. The test examines the behaviour of cable protection systems exposed to fire from outside. The tests specified in this standard are not aimed for assessing the performance of the fire protective system and the penetration seal for maintaining the requirements of the penetrated wall or ceiling (classification E / I).
This method is very different to EN 50200 for the PH classification and also to IEC 60331-11, IEC 60331-21, IEC 60331-23, and IEC 60331-25, which are not designed for fire protective systems for electrical cable systems.
This standard should be used in conjunction with EN 1363-1.
The test results apply to fire protective systems for electrical cable systems rated for voltages up to 1 kV.
The test procedure should also be used to determine the performance of protective systems for use with data and optical cables, however, verification procedures for such cables are still under development. Proposals are given in Annex C.
The protective system may include ventilation devices, inspection hatches, fixed or removable lids etc.
The tests specified in this standard are not aimed for assessing the performance of sprayed or painted coatings (e.g. intumescent or ablative coating, plastic film, epoxy resin) and similar protective layers (e.g. wrap, bandage) applied directly on the cables or bus bars as fire protective system. Also, cables and bus bars with intrinsic resistance to fire, and without fire protective systems around, are excluded (see CENELEC standard EN 50577).
This test method is not applicable for cabinets for electrical accessory containing bus systems, relays or similar.
The cables identified in this document are for testing only. It is not intended that they shall be used in protective systems installed in buildings.

Feuerwiderstandsprüfungen für Installationen - Teil 11: Brandschutzsysteme für Kabelanlagen und zugehörige Komponenten

Diese Europäische Norm legt das Verfahren zur Bewertung der Leistung von Brandschutzsystemen für elektrische Kabelanlagen und Stromschienen hinsichtlich des Erhalts der Stromkreisintegrität (Funktionserhalt) bei einer Brandbeanspruchung mit dem Ziel fest, dem Brandschutzsystem die Klassifizierung P nach EN 13501 3 zu verleihen. Die Prüfung untersucht das Verhalten der Brandschutzsysteme für Kabelanlagen bei einer Brandbeanspruchung von außen. Die in dieser Norm festgelegten Prüfungen zielen nicht darauf ab, die Leistung des Brandschutzsystems und der Abschottung in Hinblick auf die Erfüllung der Anforderungen an die Wand oder Decke mit Durchführung (Klassifizierung E/I) zu beurteilen.
Dieses Prüfverfahren unterscheidet sich grundsätzlich von den in EN 50200 für die Klassifizierung PH sowie in IEC 60331 11, IEC 60331 21, IEC 60331 23 und IEC 60331 25 beschriebenen Verfahren, die nicht für Brandschutzsysteme für elektrische Kabelanlagen ausgelegt sind.
Diese Norm sollte in Verbindung mit EN 1363 1 angewendet werden.
Die Prüfergebnisse gelten für Brandschutzsysteme für elektrische Kabelanlagen mit einer Nenn¬spannung bis 1 kV.
Dieses Prüfverfahren sollte auch angewendet werden, um die Leistung von Brandschutzsystemen zur Anwendung mit Daten- und Lichtwellenleiterkabeln zu ermitteln. Die Beurteilungsverfahren für solche Kabel sind jedoch noch in Erarbeitung. Vorschläge werden in Anhang C aufgeführt.
Das Brandschutzsystem darf Lüftungsvorrichtungen, Revisionskappen, fest installierte oder abnehmbare Verschlussdeckel usw. enthalten.
Die in dieser Norm festgelegten Prüfungen dienen nicht der Beurteilung der Leistungsfähigkeit von durch Aufspritzen oder Aufstreichen aufgebrachten Beschichtungen (z. B. dämmschichtbildende oder wärmeab-sorbierende Beschichtungen, Kunststoffbeschichtungen, Epoxidharze) oder vergleichbaren Schutzschichten (z. B. Umwicklung, Bandage), die direkt auf den Kabeln bzw. Sammelschienen als Brandschutzsystem angewendet werden. Kabel und Sammelschienen mit einem inhärenten Feuerwiderstand sowie ohne umgebende Brandschutzsysteme sind ebenfalls ausgenommen (siehe CENELEC-Norm EN 50577).
Dieses Prüfverfahren gilt nicht für Schaltschränke für elektrische Zubehörteile wie Bussysteme, Relais u. ä.

Essais de résistance au feu des installations de service - Partie 11 : Systèmes de protection incendie pour les systèmes de câbles et composants associés

La présente Norme européenne décrit la méthode permettant d’évaluer la performance des systèmes de protection des systèmes de câbles électriques et de bus bars afin que ces derniers maintiennent leur fonctionnalité électrique en cas d’incendie, dans le but de classifier le système de protection conformément à l’EN 13501-3 pour la classification P. L’essai étudie le comportement des systèmes de protection des câbles exposés au feu depuis l’extérieur. Les essais spécifiés dans la présente norme n’ont pas pour objet d’évaluer la performance au feu du système de protection incendie et du calfeutrement en ce qui concerne le respect des exigences concernant la paroi ou le plafond traversé (classification E / I).
Cette méthode est très différente de celles décrites dans l’EN 50200 pour la classification PH et dans l’IEC 60331-11, l’IEC 60331-21, l’IEC 60331-23 et l’IEC 60331-25, celles-ci n’étant pas prévues pour les systèmes de protection incendie des systèmes de câbles électriques.
Il convient d’utiliser la présente norme conjointement avec l’EN 1363-1.
Les résultats d’essai s’appliquent aux systèmes de protection incendie des systèmes de câbles électriques de tensions nominales allant jusqu’à 1 kV.
Il convient également d’utiliser ce mode opératoire d’essai pour déterminer la performance des systèmes de protection utilisés avec des câbles de données et des câbles à fibre optique. Toutefois, les modes opératoires de vérification de ces câbles sont encore en cours de développement. Des propositions sont faites dans l’Annexe C.
Le système de protection peut inclure des dispositifs de ventilation, des trappes de visite, des capots fixes ou amovibles, etc.
Les essais spécifiés dans la présente norme n’ont pas pour objet d’évaluer la performance des revêtements projetés ou peints (par exemple, revêtements intumescents ou ablatifs, film plastique, résine époxy) et des couches de protection similaires (par exemple, enrubannages, bandages) appliqués directement sur les câbles ou les bus bars en tant que système de protection incendie. En outre, les câbles et les bus bars présentant une résistance au feu intrinsèque et qui ne sont pas entourés de systèmes de protection incendie sont exclus (voir la norme EN 50577 du CENELEC).
La présente méthode d’essai n’est pas applicable aux armoires d’accessoires électriques contenant des systèmes de bus, des relais ou d’autres systèmes similaires.
Les câbles identifiés dans le présent document sont réservés aux essais. Il n’est pas prévu de devoir les utiliser dans les systèmes de protection installés dans les bâtiments.

Preskusi požarne odpornosti servisnih inštalacij - 11. del: Požarni zaščitni sistem za kabelske sisteme in pripadajoče dele (vključuje dopolnilo A1)

Ta evropski standard opisuje metodo ocenjevanja učinkovitosti zaščitnih sistemov pri sistemih električnih kablov in sistemov zbiralk za namene vzdrževanja neprekinjenosti tokokroga v požarnih razmerah za razvrščanje zaščitnega sistema v skladu s standardom EN 13501-3 za razvrščanje P. Preskus preučuje obnašanje sistemov za zaščito kablov, ki so ognju izpostavljeni z zunanje strani. Preskusi, ki jih določa ta standard, niso namenjeni ocenjevanju učinkovitosti požarnega zaščitnega sistema in tesnjenja prebojev za ohranjanje zahtev za steno ali strop pri širjenju požara (razvrščanje E/I).
Ta metoda se zelo razlikuje od standarda EN 50200 za razvrščanje PH in tudi od standardov IEC 60331-11, IEC 60331-21, IEC 60331-23 ter IEC 60331-25, ki niso zasnovani za požarne zaščitne sisteme za električne kabelske sisteme.
Ta standard naj bi se uporabljal v povezavi s standardom EN 1363-1.
Rezultati preskušanja veljajo za požarne zaščitne sisteme za električne kabelske sisteme, ocenjene za napetosti do 1 kV.
Preskusni postopek naj bi se uporabljal tudi za določevanje učinkovitosti zaščitnih sistemov za uporabo s podatkovnimi in optičnimi kabli, vendar so postopki preverjanja za takšne kable še v pripravi. Predlogi so podani v dodatku C.
Zaščitni sistem lahko vključuje prezračevalne naprave, lopute za namene pregleda, fiksne ali odstranljive pokrove itd.
Preskusi, določeni v tem standardu, niso namenjeni ocenjevanju učinkovitosti brizganih ali barvanih premazov (npr. intumescentna ali ablativna prevleka, plastična folija, epoksidna smola) in podobnih zaščitnih slojev (npr. ovoj, povoj), nanesenih neposredno na kable ali vodila kot požarno zaščitni sistem. Prav tako so izključeni kabli in vodila z lastno požarno odpornostjo in brez požarnih zaščitnih sistemov (glej standard CENELEC EN 50577).
Ta preskusna metoda ni uporabna za omarice z električnimi dodatki, ki vsebujejo sisteme vodil, releje ali podobno.
Kabli, navedeni v tem dokumentu, so samo za preskušanje. Ni predvideno, da bi se uporabljali v zaščitnih sistemih, nameščenih v stavbah.

Introduction

The purpose of this test is to evaluate the ability of the protective system to allow cables and

components of their installation (connectors, glands, junctions, mountings, etc.) to maintain

during a defined time a reliable function whilst exposed to fire. The purpose of this test is to

verify compliance with requirements regarding the circuit integrity of systems for example as

those for firefighting lifts, pressure boosters, emergency lighting, fire alarm systems etc.

The fire exposure conditions and general arrangement in this European Standard are similar to

those given in EN 50577, developed by CLC/TC 20, and prCLC/TR 50658 under development by

CLC/TC 213. Each of these standards has been developed under a Mode 4 co-operation between

CEN TC 127, CLC/TC 213 and CLC/TC 20.

CAUTION: The attention of all persons concerned with managing and carrying out this fire

resistance test is drawn to the fact that fire testing may be hazardous and that there is a

possibility that toxic and/or harmful smoke and gases may be evolved during the test.

Mechanical and operational hazards may also arise during the construction of the test elements

or structures, their testing and disposal of test residues.

An assessment of all potential hazards and risks to health should be made and safety

precautions should be identified and provided. Written safety instructions should be issued.

Appropriate training should be given to relevant personnel. Laboratory personnel should

ensure that they follow written safety instructions at all times.

1 Scope

This European Standard describes the method to evaluate the performance of protective

systems for electrical cable and busbar systems in order to maintain the circuit integrity under

fire conditions to classify the protective system according to EN 13501-3 for the P classification.

The test examines the behaviour of cable protection systems exposed to fire from outside. The

tests specified in this standard are not aimed for assessing the performance of the fire

protective system and the penetration seal for maintaining the requirements of the penetrated

wall or ceiling (classification E / I).

This method is very different to EN 50200 for the PH classification and also to IEC 60331-11,

IEC 60331-21, IEC 60331-23, and IEC 60331-25, which are not designed for fire protective

systems for electrical cable systems.
This standard should be used in conjunction with EN 1363-1.

The test results apply to fire protective systems for electrical cable systems rated for voltages up

to 1 kV.

The test procedure should also be used to determine the performance of protective systems for

use with data and optical cables, however, verification procedures for such cables are still under

development. Proposals are given in Annex C.

The protective system may include ventilation devices, inspection hatches, fixed or removable

lids etc.

The tests specified in this standard are not aimed for assessing the performance of sprayed or

painted coatings (e.g. intumescent or ablative coating, plastic film, epoxy resin) and similar

protective layers (e.g. wrap, bandage) applied directly on the cables or bus bars as fire

protective system. Also, cables and bus bars with intrinsic resistance to fire, and without fire

protective systems around, are excluded (see CENELEC standard EN 50577).

This test method is not applicable for cabinets for electrical accessory containing bus systems,

relays or similar.

!The cables identified in this document are for testing only. It is not intended that they shall

be used in protective systems installed in buildings."
