Fire resistance tests for service installations - Part 9: Single compartment smoke extraction ducts
This part of EN 1366 specifies a test method for determining the fire resistance of smoke extraction ducts that are used for single compartment applications only. In such applications, the smoke extraction system is only intended to function up to flashover (typically 600 °C).
This method of test is only suitable for ducts constructed from non-combustible materials (class A1 and A2-s1, d0 according to EN 13501-1).
It is applicable only to four sided and circular ducts. One-, two- and three-sided ducts are not covered. This document is applicable only for the standard sizes or smaller as described.
This test method of part 9 is applicable only to smoke extraction ducts that do not pass into other fire compartments. For smoke extraction ducts that pass into other compartments, the method of test described in EN 1366-8 is used.
The smoke extraction duct is part of the smoke extraction system which also includes smoke control dampers and smoke extract fans.
Feuerwiderstandsprüfungen für Installationen - Teil 9: Entrauchungsleitungen für einen Einzelabschnitt
Dieser Teil von EN 1366 legt ein Prüfverfahren zur Ermittlung der Feuerwiderstandsfähigkeit von Entrauchungsleitungen fest, die nur für die Anwendung in einem Einzelabschnitt eingesetzt werden. Bei solchen Anwendungen ist beabsichtigt, dass die Rauchabzugsanlage nur bis zum Flashover (typischerweise 600 °C) arbeitet.
Dieses Prüfverfahren ist nur für aus nichtbrennbaren Baustoffen (Klasse A1 und A2 s1, d0 nach EN 13501 1) konstruierte Leitungen geeignet.
Es ist nur für vierseitige und kreisförmige Leitungen geeignet. Ein-, zwei- und dreiseitige Leitungen werden nicht abgedeckt. Dieses Dokument gilt nur für Standardmaße oder kleinere Größen, wie beschrieben.
Dieses Prüfverfahren von Teil 9 gilt nur für Entrauchungsleitungen, die nicht in weitere Brandabschnitte führen. Für Entrauchungsleitungen, die in weitere Brandabschnitte hineinführen, ist das in EN 1366 8 beschriebene Prüfverfahren anzuwenden.
Die Entrauchungsleitung ist Bestandteil der Rauchabzugsanlage, welche ebenfalls Entrauchungsklappen und Rauchabzüge umfasst.
Essais de résistance au feu des installations techniques - Partie 9 : Conduits d'extraction de fumées relatifs à un seul compartiment
La présente partie de l’EN 1366 spécifie une méthode d’essai pour déterminer la résistance au feu des conduits d’extraction de fumées qui sont utilisés pour des applications relatives à un seul compartiment. Dans de telles applications, le système d’extraction de fumées vise à fonctionner seulement jusqu’à l’embrasement généralisé (600 °C en général).
Cette méthode d’essai n’est valable que pour des conduits fabriqués à partir de matériaux non combustibles (classe A1 et A2-s1, d0 conformément à l’EN 13501-1).
Les essais ne s’appliquent qu’aux conduits à quatre faces et aux conduits circulaires. Les conduits à une seule face, à deux ou trois faces ne sont pas couverts. Le présent document ne s’applique qu’aux tailles standards ou inférieures conformément à la description.
Cette méthode d’essai de la partie 9 est applicable seulement aux conduits d’extraction de fumées qui ne passent pas dans d’autres compartiments feu. Pour les conduits d’extraction de fumées qui passent dans d’autres compartiments, la méthode d’essai décrite dans l’EN 1366-8 est utilisée.
Le conduit d’extraction de fumées fait partie intégrante du système d’extraction de fumées qui comprend également des volets de désenfumage et des ventilateurs de désenfumage.
