FprEN 1366-3

Fire resistance tests for service installations - Part 3: Penetration seals

This Part of EN 1366 specifies a method of test and criteria for the evaluation (including field of application rules) of the ability of a penetration seal to maintain the fire resistance of a separating element at the position at which it has been penetrated by a service. Penetration seals used to seal gaps around chimneys, air ventilation systems, fire rated ventilation ducts, fire rated service ducts, shafts and smoke extraction ducts are excluded from this standard except for mixed penetration seals. The fire resistance of those services itself cannot be assessed with the methods described in this standard.
Supporting constructions are used in this standard to represent separating elements such as walls or floors. These simulate the interaction between the test specimen and the separating element into which the sealing system is to be installed in practice.
This European Standard is used in conjunction with EN 1363-1.
The purpose of this test described in this standard is to assess:
a)   the effect of such penetrations on the integrity and insulation performance of the separating element concerned;
b)   the integrity and insulation performance of the penetration seal;
c)   the insulation performance of the penetrating service or services, and where necessary, the integrity failure of a service.
No information can be implied by the test concerning the influence of the inclusion of such penetrations and sealing systems on the loadbearing capacity of the separating element.
It is not the intention of this test to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes. Such phenomena are only to be noted in describing the general behaviour of test specimens during the test.
This test is not intended to supply any information on the ability of the penetration seal to withstand stress caused by movements or displacements of the penetrating services.

Feuerwiderstandsprüfungen für Installationen - Teil 3: Abschottungen

Dieser Teil der Normenreihe EN 1366 legt ein Prüfverfahren und Kriterien zur Beurteilung (inklusive Regeln zum direkten Anwendungsbereich) der Fähigkeit einer Abschottung fest, den Feuerwiderstand eines raumabschließenden Bauteils an der Stelle, wo durch dieses eine oder mehrere Leitungen durchgeführt werden, aufrechtzuerhalten. Abschottungen für Zwischenräume und Öffnungen um Kamine, Lüftungssysteme, Lüftungsleitungen, Installationskanäle und -schächte sowie Entrauchungsleitungen und kombinierte Abschottungen mit definierter Feuerwiderstandsdauer sind von diesem Teil der Normenreihe EN 1366 ausgenommen.
ANMERKUNG   Ein Dokument, das sich mit Abschottungen einschließlich Leitungen und Dämpfern befasst, befindet sich derzeit in Vorbereitung (prEN 15882 5).
In diesem Teil der Normenreihe EN 1366 werden Tragkonstruktionen stellvertretend für raumabschließende Bauteile, wie zum Beispiel Wände und Decken, verwendet. Diese stellen die Wechselwirkungen zwischen Prüfkörper und dem raumabschließenden Bauteil, in welchen die Abschottung in der Praxis eingebaut werden soll, nach.
Dieser Teil der Normenreihe EN 1366 ist für die Verwendung in Verbindung mit EN 1363 1 vorgesehen.
Die in diesem Teil der Normenreihe EN 1366 beschriebene Prüfung dient der Beurteilung des Raumabschlusses und Wärmedämmverhaltens der Abschottung, der durchlaufenden Leitung(en) und des raumabschließenden Bauteils um die Abschottung.
Die Prüfung ermöglicht keine Aussagen darüber, inwieweit das Vorhandensein derartiger Durchführungen und Abschottungen einen Einfluss auf die Tragfähigkeit des raumabschließenden Bauteils ausübt.
Es wird angenommen, dass der Sturz über einer Abschottung in der Wand auf jeden Fall im warmen und kalten Zustand so ausgelegt ist, dass er die Abschottung nicht zusätzlich vertikal belastet.
Der Zweck dieser Prüfung besteht nicht darin, quantitative Angaben über die Leckrate von Rauch und/oder heißen Gasen oder die Übertragung bzw. Erzeugung von Rauchgasen zu ermitteln. Derartige Beobachtungen werden nur bei der Beschreibung des allgemeinen Verhaltens der Probekörper während der Prüfung im Prüfbericht festgehalten.
Prüfungen in Übereinstimmung mit diesem Teil der Normenreihe EN 1366 liefern keine Angaben über das Leistungsverhalten einer Abschottung, Spannungen zu widerstehen, die durch Bewegungen oder Verschiebungen der durchlaufenden Leitungen erzeugt werden.
Das Risiko einer Brandausbreitung nach unten, verursacht durch brennendes Material, welches zum Beispiel durch ein Rohr nach unten in das darunterliegende Geschoss tropft, wird derzeit nicht in diesem Dokument behandelt.
Die Prüfungen in Übereinstimmung mit diesem Teil der Normenreihe EN 1366 befassen sich nicht mit Risiken in Verbindung mit dem Austritt gefährlicher Flüssigkeiten oder Gase aufgrund des Versagens von Rohren im Brandfall.
Bei den Prüfungen in Übereinstimmung mit diesem Teil der Normenreihe EN 1366 von Rohrabschottungen für Rohre von Rohrpostsystemen, Druckluftsystemen usw. wird eine Situation nachgestellt, in der die Systeme im Brandfall abgeschaltet sind.
Erläuterungen zu diesem Prüfverfahren sind im Anhang H angegeben.
Alle Werte ohne vorgegebene Grenzabweichungen in diesem Dokument sind Nennwerte, sofern nicht anders angegeben.
Alle Rohrdurchmesser sind Außendurchmesser, sofern nicht anders angegeben.

Essais de résistance au feu des installations techniques - Partie 3 : Calfeutrements de trémies

La présente partie de la série EN 1366 spécifie une méthode d’essai et des critères pour l’évaluation (incluant des règles de domaine d’application directe) de l’aptitude d’un calfeutrement de trémie à maintenir la résistance au feu d’un élément séparatif à l’endroit auquel il est traversé par un ou plusieurs traversants. Les calfeutrements de trémies utilisés pour combler les espaces autour des cheminées, des systèmes de ventilation, des conduits de ventilation classés au feu, des gaines techniques classées au feu et des conduits d’extraction de fumée sont exclus du domaine d’application de la présente partie de la série EN 1366, de même que les calfeutrements de trémies combinés.
NOTE   Un document traitant des calfeutrements de trémies incluant des conduits et des clapets, est en préparation (prEN 15882-5).
Des constructions support sont utilisées dans la présente partie de la série EN 1366 pour représenter les éléments séparatifs tels que les murs ou les planchers. Elles simulent l’interaction entre l’élément d’essai et l’élément séparatif dans lequel le système de calfeutrement doit être installé dans les conditions réelles.
La présente partie de la série EN 1366 est destinée à être utilisée conjointement avec l’EN 1363 1.
L’objet des essais décrits dans la présente partie de la série EN 1366 est d’évaluer l’étanchéité au feu et la performance d’isolation du calfeutrement de trémie, du ou des traversants et de l’élément séparatif dans la zone environnante du calfeutrement.
Aucune information ne peut être déduite de l’essai en ce qui concerne l’incidence de l’intégration de ces trémies et de ces calfeutrements de trémies sur la capacité portante de l’élément séparatif.
Dans chaque cas, le linteau situé au-dessus d’un calfeutrement de trémie dans la paroi est présumé dimensionné à l’état chaud et froid de sorte qu’il n’applique aucune charge verticale supplémentaire sur le calfeutrement.
Cet essai n’a pas pour but de fournir des informations quantitatives sur le taux d’étanchéité aux fumées et/ou aux gaz chauds, ou sur la transmission de gaz chauds ou la génération de fumées. Ces phénomènes sont uniquement consignés dans le rapport d’essai qui décrit le comportement général des éléments au cours de l’essai.
Les essais réalisés conformément à la présente partie de la série EN 1366 ne sont pas destinés à fournir des informations sur la capacité du calfeutrement de trémie à résister aux contraintes engendrées par les mouvements ou les déplacements des traversants.
Le risque de propagation du feu vers le bas provoquée par un matériau en feu coulant, par exemple, à travers un tuyau vers les étages inférieurs, est actuellement exclu du présent document.
Les essais effectués conformément à la présente partie de la série EN 1366 ne couvrent pas les risques associés aux fuites de liquides ou de gaz dangereux dues à la rupture de tuyaux en cas d’incendie.
Les essais réalisés conformément à la présente partie de la série EN 1366 sur des calfeutrements de trémies pour des tuyaux de systèmes de distribution pneumatiques, de systèmes d’air sous pression, etc. simulent une situation où ces systèmes sont coupés en cas d’incendie.
Des notes explicatives de cette méthode d’essai figurent à l’Annexe H.
Sauf spécification contraire, toutes les valeurs indiquées sans tolérances dans le présent document sont des valeurs nominales.
Tous les diamètres de tuyaux sont des diamètres externes, sauf spécification contraire.

Introduction

This part of the EN 1366 series has been prepared to provide a method of test for assessing the

contribution of a penetration seal to the fire resistance of separating elements when they have been

penetrated by a service or services.
Caution

The attention of all persons concerned with managing and carrying out fire resistance testing is

drawn to the fact that fire testing can be hazardous and that there is a possibility that toxic and/or

harmful smoke and gases will be emitted during the test. Mechanical and operational hazards might

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 the EN 1366 series specifies a method of test and criteria for the evaluation (including

field of direct application rules) of the ability of a penetration seal to maintain the fire resistance of

a separating element at the position at which it has been penetrated by a service or services.

Penetration seals used to seal gaps around chimneys, air ventilation systems, fire rated ventilation

ducts, fire rated service ducts, shafts and smoke extraction ducts as well as combined penetration

seals are excluded from this part of the EN 1366 series. Supporting constructions are used in this

part of the EN 1366 series to represent separating elements such as walls or floors. These simulate

the interaction between the test specimen and the separating element into which the sealing system

is to be installed in practice.

This part of the EN 1366 series is intended to be used in conjunction with EN 1363-1.

The purpose of a test described in this part of the EN 1366 series is to assess the integrity and

insulation performance of the penetration seal, of the penetrating service or services and of the

separating element in the surrounding area of the penetration seal.

No information can be implied by the test concerning the influence of the inclusion of such

penetrations and penetration seals on the loadbearing capacity of the separating element.

It is assumed that in each case the lintel above a penetration seal in the wall is designed in hot and

cold state in a way that it does not apply any additional vertical load on the penetration seal.

It is not the intention of this test to provide quantitative information on the rate of leakage of smoke

and/or hot gases or on the transmission or generation of fumes. Such phenomena are only noted in

the test report in describing the general behaviour of test specimens during the test.

Tests in accordance with this part of the EN 1366 series are not intended to supply any information

on the ability of the penetration seal to withstand stress caused by movements or displacements of

the penetrating services.

The risk of spread of fire downwards caused by burning material, which drips through a pipe

downwards to floors below, cannot be assessed with this test.

Tests in accordance with this part of the EN 1366 series do not address any risks associated with

leakage of dangerous liquids or gases caused by failure of pipes in case of fire.

Tests in accordance with this part of the EN 1366 series of pipe penetration seals for pipes of

pneumatic dispatch systems, pressurized air systems, etc. simulate a situation where the systems are

shut off in case of fire.
Explanatory notes to this test method are given in Annex H.

All values given without tolerances in this document are nominal ones unless otherwise specified.

All pipe diameters are outside diameters unless otherwise specified.

cable box
housing with intumescent inlays that forms a channel

Note 1 to entry: A cable box is fitted with a device to prevent the passage of cold smoke.

3.1.19
pipe closure device
reactive device to seal penetrations for insulated or non-insulated pipes

Note 1 to entry: Pipe closure devices are e.g. collars, wraps and sleeves: Collars incorporate an outer casing

which acts as a restraint for an intumescent material, enabling the collar to be either surface fixed to the

separating element or incorporated within it; wraps are usually wrapped around the pipe and located within

the separating element, which acts as a restraint for the intumescent material; Sleeves pass completely through

the separating element and may include an outer casing.
