Fire resistance tests for service installations - Part 5: Service ducts and shafts
This Part of EN1366 specifies a method for determining the fire resistance of horizontal service ducts and vertical service shafts, which pass through walls or floors and enclose pipes and cables. The test examines the behaviour of ducts and shafts exposed to fire from outside and from inside the duct. This standard is read in conjunction with EN 1363-1.
This standard does not examine the risk of fire spread as a result of thermal conduction along the piping installed in service ducts or shafts, or thermal conduction through the media these pipes carry. It does not cover the risk of damage produced by thermal elongation or shortening as a result of fire, or damaged pipe suspensions. This standard does not give guidance on how to test one, two or three sided service ducts or shafts.
NOTE Guidance on testing service ducts and shafts of less than four sides will be covered in the extended field of application rules being developed by CEN/TC 127.
This test is unsuitable for evaluating service ducts with internal barriers at walls and floors.
Whilst the walls of service ducts or shafts tested to this method may provide specified levels of integrity or insulation, testing to this standard does not replace the testing of the functional endurance of small electrical cables which is covered in EN 50200.
Fire resistance testing of ducts for air distribution systems is covered in EN 1366-1.
Feuerwiderstandsprüfungen für Installationen - Teil 5: Installationskanäle und -schächte
Dieser Teil von EN 1366 legt ein Prüfverfahren für die Ermittlung der Feuerwiderstandsfähigkeit von Installationskanälen und -schächten, die Wände oder Decken durchqueren und Rohre und Kabel beinhalten, fest. Die Prüfung bestimmt das Brandverhalten von Installationskanälen und -schächten bei Brandbeanspruchung sowohl von außerhalb als auch von innerhalb des Installationskanals und -schachtes. Diese Norm gilt in Verbindung mit EN 1363-1.
Diese Norm befasst sich nicht mit der Gefahr der Brandübertragung infolge von Wärmefortleitung entlang der Rohrleitungen, die in Installationskanälen oder -schächten installiert sind, oder Wärmefortleitung über die Medien, welche diese Rohrleitungen führen. Diese Prüfung deckt auch nicht die Gefahr der Beschädigung, hervorgerufen durch thermische Verlängerung oder Verkürzung infolge eines Brandes, oder beschädigter Rohraufhängungen ab. Diese Prüfung gibt keine Anleitung zum Prüfen von ein-, zwei- oder dreiseitigen Installationskanälen oder Installationsschächten.
ANMERKUNG Eine Anleitung zum Prüfen von Installationskanälen und Installationsschächte mit weniger als vier Seiten wird im erweiterten Anwendungsbereich, der bei CEN/TC 127 in Bearbeitung ist, gegeben.
Diese Prüfung ist ungeeignet für die Bewertung von Installationskanälen mit inneren Verschlüssen an Wänden und Decken.
Obwohl die Wände der nach diesem Verfahren geprüften Installationskanäle oder -schächte eine bestimmte Klasse eines Raumabschlusses oder einer Wärmedämmung liefern können, ersetzt eine Prüfung nach dieser Norm nicht die Prüfung der Funktionsdauer von elektrischen Kabeln nach EN 50200.
Die Feuerwiderstandsprüfung von Lüftungsleitungen wird in EN 1366-1 behandelt.
Essais de résistance au feu des installations de service - Partie 5: Gaines pour installation technique
La présente partie de l'EN 1366 prescrit une méthode de détermination de la résistance au feu des gaines horizontales et verticales pour installation technique qui traversent les murs ou les planchers et qui enferment des tuyaux et des câbles. L'essai permet d'évaluer le comportement des gaines exposées à un feu attaquant de l'intérieur ou de l'extérieur de cette dernière. La présente norme doit être lue conjointement avec l'EN 1363-1.
La norme ne traite pas des risques de propagation du feu dus au transfert de chaleur se produisant dans les canalisations installées dans les gaines pour installation technique ou dans le milieu qu'elles transportent. Elle ne couvre également pas les risques de dégradation thermique produits par allongement ou raccourcissement dus au feu ou de détérioration des dispositifs de suspension des tuyaux. Cette norme ne fournit pas d'éléments sur la façon d'essayer des gaines pour installation technique à un, deux ou trois cotés.
NOTE Les éléments sur la façon d'essayer des gaines pour installation technique à un, deux ou trois cotés seront présentés dans les règles d'application étendues en court de développement au CEN/TC 127.
Le présent essai ne convient pas à l'évaluation des gaines pour installation technique avec recoupements internes au niveau des murs et planchers.
Bien que les parois des gaines pour installation technique soumises au présent essai peuvent fournir des niveaux spécifiques d'étanchéité au feu ou d'isolation, les essais de la présente norme ne remplacent pas les essais de résistance fonctionnelle des câbles électriques traités dans l'EN 50200.
Les essais de résistance au feu des conduits des circuits de distribution d'air sont traités dans l'EN 1366-1.

EN 1366-5:2003 (E)5IntroductionThe purpose of this test is to measure the ability of a representative service duct or shaft to resist thespread of fire from one fire compartment to another with fire attack from inside or outside the duct orshaft. The test specimens incorporate joints and access openings as intended in practice and aresuspended as they would be in practice. Test specimens of service ducts are not loaded as inpractice but a standard load is included to represent a typical service load. Test specimens of serviceshafts are not loaded as in practice, but a standard load is included to represent a typical service load.CautionThe attention of all persons concerned with managing and carrying out this fire resistance test isdrawn to the fact that fire testing may be hazardous and that there is a possibility that toxic and/orharmful smoke and gases may be evolved during the test. Mechanical and operational hazards mayalso arise during the construction of the test elements or structures, their testing and disposal of testresidues.An assessment of all potential hazards and risks to health should be made and safety precautionsshould be identified and provided. Written safety instructions should be issued. Appropriate trainingshould be given to relevant personnel. Laboratory personnel should ensure that they follow writtensafety instructions at all times.SIST EN 1366-5:2003
