Fire resistance tests for service installations - Part 3: Penetration seals; German version EN 1366-3:2021+A1:2024/AC:2025

Edition date: 2026-03-01
In Force
Available languages: English, German
Summary: 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. NOTE EN 15882-5 [6] deals with penetration seals including ducts and dampers. 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 e. g. through a pipe downwards to floors below, is at present excluded from this document. 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.

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 umlaufende Fugen um Kamine, Lüftungssysteme, Lüftungsleitungen, Installationskanäle und -schächte sowie Entrauchungsleitungen und erweiterte Kombiabschottungen mit definierter Feuerwiderstandsdauer sind von diesem Teil der Normenreihe EN 1366 ausgenommen. EN 15882-5 befasst sich mit Abschottungen, die Lüftungsleitungen und Brandschutzklappen enthalten. 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 raumabschließendem Bauteil, in welche 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 in jedem Fall im heißen 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 Prüfkörper 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.
