prEN 1366-11

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

This part of EN 1366 describes a method to evaluate the maintenance of circuit integrity of electrical cable systems and associated components (connectors, glands, junctions, mountings, etc.) under fire conditions to classify the protective system according to EN 13501-3. The test examines the behaviour of cable protection systems exposed to fire from outside.
This standard is 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.
NOTE   This test procedure may be used to determine the functionality for optical and data cables in case of fire but this does not form part of the classification procedure.
The protection 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 are excluded.
This method is very different to EN 50200 and also to IEC 60331-11, -21, -23 and -25, which are not designed for fire protective systems for electrical cable systems.
This test method is not applicable for cabinets for electrical accessory containing bus systems, relays or similar.

Feuerwiderstandsprüfungen für Installationen - Teil 11: Funktionserhalt von elektrischen Kabelanlagen mit Brandschutzsystem

Dieser Teil der Normenreihe EN 1366 beschreibt das Verfahren zur Bewertung des Funktionserhalts von elektrischen Kabelanlagen sowie der zugehörigen Installationskomponenten (Steckverbinder, Schraubverbindungen, Verbindungselemente, Halterungen usw.) bei einer Brandbeanspruchung, um das Brandschutzsystem nach EN 13501-3 zu klassifizieren. Diese Prüfung beurteilt das Verhalten der Brandschutzsysteme für Kabelanlagen bei einer Brandbeanspruchung von außen.
Diese Norm gilt zusammen mit EN 1363-1.
Die Ergebnisse aus den Brandprüfungen gelten für Brandschutzsysteme für elektrische Kabelanlagen mit einer Nennspannung bis zu 1 kV.
ANMERKUNG   Dieses Prüfverfahren kann angewandt werden, um die Funktionalität von Glasfaserkabeln und Datenleitungen in einem Brandfall zu ermitteln. Es stellt jedoch kein Bestandteil des Klassifizierungsvorgangs dar.
Das Brandschutzsystem kann Lüftungselemente, Revisionskappen, fest installierte oder abnehmbare Verschlussdeckeln usw. enthalten.
Die in dieser Norm spezifizierten Prüfungen dienen nicht der Beurteilung der Leistungsfähigkeit von gespritzten oder gestrichenen Beschichtungen (z. B. dämmschichtbildende bzw. wärmeabsorbierende Beschichtung, Kunststoffbeschichtung, Epoxidharz) oder ähnlichen Schutzbeschichtungen (z. B. Umwicklung, Bandage), welche direkt auf den Kabeln bzw. Stromschienen als Schutzsystem angewendet werden. Kabel und Stromschienen mit einem eigenständigen Feuerwiderstand fallen ebenfalls nicht unter den Anwendungsbereich dieser Norm.
Dieses Prüfverfahren unterscheidet sich grundsätzlich von denen in EN 50200 sowie in IEC 60331  11,  21,  23 und  25 beschriebenen, welche für Brandschutzsysteme für elektrische Kabelanlagen nicht geeignet sind.
Dieses Prüfverfahren gilt nicht für elektrische Schaltschränke mit Zubehörteilen wie Sammelleitungen, Schutzrelais 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 partie de l’EN 1366 décrit une méthode permettant d’évaluer le maintien de la fonctionnalité
électrique des systèmes de câbles électriques et de leurs composants associés (connecteurs, presse-étoupe,
jonctions, fixations, etc.) en cas d’incendie, dans le but de classifier le système de protection conformément à
l’EN 13501-3. L’essai étudie le comportement des systèmes de protection des câbles exposés au feu depuis
l’extérieur.
La présente norme est utilisée 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.
NOTE Ce mode opératoire d’essai peut être utilisé pour déterminer la fonctionnalité des câbles à fibre optique et des
câbles de données en cas d’incendie, mais il ne fait pas partie de la procédure de classification.
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 sont exclus.
Cette méthode est très différente de celles décrites dans l’EN 50200 et dans la CEI 60331-11, -21, -23 et -25,
celles-ci n’étant pas prévues pour les systèmes de protection incendie des systèmes de câbles électriques.
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.

Overview

prEN 1366-11 specifies a standardized fire resistance test method for evaluating the ability of fire protective systems for cable systems and associated components (connectors, glands, junctions, mountings, etc.) to maintain circuit integrity when exposed to fire from the outside. The procedure is designed to classify protective systems in accordance with EN 13501-3 and is intended for electrical cable systems rated up to 1 kV. The standard is used together with EN 1363-1 (general fire test requirements).

Key topics and technical requirements

• Objective: Assess maintenance of circuit integrity (no short-circuit or interruption) for power, signal and bus bar installations inside protective systems during a defined fire exposure.
• Scope limits: Applies to ducts, shafts, trunking, jacket enclosures, ventilation devices, inspection hatches and removable lids - but excludes sprayed/painted coatings applied directly to cables, intrinsically fire-resistant cables/bus bars, and electrical cabinets with relays or complex bus systems.
• Furnace and test set-up: Test follows EN 1363-1; minimum furnace internal size 2000 mm x 3000 mm. Specimen is installed horizontally; exposed duct length ≥ 3000 mm (or not shorter than 2 × suspension span + 250 mm at each end).
• Heating and pressure: Heating curve per EN 1363-1. Furnace pressure controlled to at least 20 Pa at top of the protective system; positive pressure zone must exceed 10 Pa (minimum 10 Pa at lowest point).
• Instrumentation: Plate thermocouples at mid-height on each side (100 mm from specimen) at two longitudinal positions, strict maximum spacing rules (max 1.5 m between thermocouples; max 0.8 m from furnace wall). Power supply arrangements and continuity/short-circuit monitoring for power, signal and bus bar circuits are specified.
• Performance criteria: Circuit integrity is maintained if there is no short circuit or circuit interruption during the exposure. Optical/data cable functionality can be tested but is not part of classification.
• Test report & applicability: Detailed reporting and clear limitations on the field of direct application (sizes, orientations, fixing, suspension, penetrations) are required.

Applications and who uses it

• Fire test laboratories performing classification tests for cable protection systems.
• Manufacturers of ducts, trunking, cable enclosures, cable trays and fire protective systems seeking EN 13501-3 classification.
• Fire safety engineers, specifiers and building designers verifying cable management solutions for fire resilience in buildings and infrastructure.

This document is currently submitted to the CEN Enquiry.
This document has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
EN 1366, Fire resistance tests for service installations, consists of the following parts:
 Part 1: Ducts
 Part 2: Fire dampers
 Part 3: Penetration seals
 Part 4: Linear joint seals
 Part 5: Service ducts and shafts
 Part 6: Raised access floors and hollow floors
 Part 7: Closures for conveyors and trackbound transportation systems
 Part 8: Smoke extraction ducts
 Part 9: Single compartment smoke extraction ducts (in course of preparation)
 Part 10: Smoke control dampers
 Part 11: Fire Protection system for essential services (in course of preparation)

Introduction
The purpose of this test is to evaluate the ability of the protective system to allow cables plus components of
their installation (connectors, glands, junctions, mountings, etc.) to maintain during a defined time a reliable
function whist exposed to fire. Therefore cables are used with worst case behaviour in fire (high temperature)
as indicator that the fire protective system gives the necessary protection during a given time period.
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 part of EN 1366 describes a method to evaluate the maintenance of circuit integrity of electrical cable
systems and associated components (connectors, glands, junctions, mountings, etc.) under fire conditions to
classify the protective system according to EN 13501-3. The test examines the behaviour of cable protection
systems exposed to fire from outside.
This standard is 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.
NOTE This test procedure may be used to determine the functionality for optical and data cables in case of fire but
this does not form part of the classification procedure.
The protection 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 are excluded.
This method is very different to EN 50200 and also to IEC 60331-11, -21, -23 and -25, which are not designed
for fire protective systems for electrical cable systems.
This test method is not applicable for cabinets for electrical accessory containing bus systems, relays or
similar.
