Fire resistance tests for service installations - Part 1: Ventilation ducts

This Part of EN 1366 specifies a method for determining the fire resistance of vertical and horizontal ventilation ducts including those access panels, which are integral part of the tested ducts. The test examines the behaviour of ducts exposed to fire from the outside (duct A) and fire inside the duct (duct B). This Standard is used in conjunction with EN1363-1.
Annex A provides general guidance and gives background information.
This European Standard is not applicable to:
a)   ducts whose fire resistance depends on the fire resistance performance of a ceiling or wall(where ducts are located in cavities enclosed by fire-resistant shafts or ceilings);
b)   ducts containing fire dampers at points where they pass through fire separations;
c)   one, two or three sided ducts;
d)   fixing of suspension devices (e.g. anchors) to floors or walls.

Feuerwiderstandsprüfungen für Installationen - Teil 1: Lüftungsleitungen

Diese Europäische Norm legt ein Verfahren zur Bestimmung des Feuerwiderstands von vertikalen und hori-zontalen Lüftungsleitungen, einschließlich Zugangsklappen, fest, die fester Bestandteil der zu prüfenden Leitungen sind. Die Prüfung untersucht das Verhalten von Leitungen, die Brandeinwirkung von außen (Leitung A) sowie Brandeinwirkung innerhalb der Leitung (Leitung B) ausgesetzt sind. Diese Europäische Norm wird in Zusammenhang mit EN 1363 1 angewendet.
Anhang A enthält eine allgemeine Anleitung und Hintergrundinformationen.
Diese Europäische Norm gilt nicht für:
a)   Leitungen, deren Feuerwiderstand von der Feuerwiderstandsklasse einer Decke oder Wand abhängig ist (wobei Leitungen in Hohlräumen in feuerwiderstandsfähigen Schächten oder Decken eingeschlossen sind);
b)   Leitungen mit Brandschutzklappen an den Durchführungsstellen von raumabschließenden Bauteilen;
c)   ein-, zwei- oder dreiseitige Leitungen;
d)   Befestigungsmittel von Abhängevorrichtungen (z. B. Anker) an Decken oder Wänden.

Essais de résistance au feu des installations techniques - Partie 1: Conduits de ventilation

La présente Norme européenne spécifie une méthode de détermination de la résistance au feu des conduits de ventilation horizontaux ou verticaux, y compris les trappes d’accès qui font partie intégrante des conduits soumis à l’essai. L’essai examine le comportement des conduits exposés au feu de l’extérieur (conduit A) et de l’intérieur (conduit B). La présente Norme européenne est utilisée conjointement avec l’EN 1363-1.
L’Annexe A donne des lignes directrices générales et des informations de base.
La présente Norme européenne n’est pas applicable :
a)   aux conduits dont la résistance au feu dépend de la performance de résistance au feu d’un plafond ou d’un mur (lorsque les conduits se trouvent à l’intérieur de cavités situées dans des gaines ou des plafonds résistant au feu) ;
b)   aux conduits comportant des clapets résistant au feu au niveau des cloisonnements coupe-feu ;
c)   aux conduits à un, deux ou trois côtés ;
d)   à la fixation des dispositifs de suspension (par exemple ancrages) aux planchers ou aux murs.

Preskusi požarne odpornosti servisnih inštalacij - 1. del: Ventilacijski kanali

Ta del standarda EN 1366 določa metodo za ugotavljanje požarne odpornosti vodoravnih in navpičnih ventilacijskih kanalov, vključno s tistimi ploščami za dostop, ki so sestavni del preskušenih kanalov. Preskus preučuje vedenje kanalov, izpostavljenih požaru z zunanje strani (kanal A) in z notranje strani (kanal B). Ta standard se uporablja v povezavi s standardom EN 1363-1.
Dodatek A podaja splošne smernice in dodatne informacije.
Ta evropski standard se ne uporablja za:
a) kanale, katerih požarna odpornost je odvisna od požarne odpornosti stropa ali stene (kjer se kanali nahajajo v luknjah obdanih z proti ognju odpornimi kanali ali stropi);
b) kanale, ki vsebujejo dušilnike ognja na točkah, kjer prehajajo skozi požarne ločevalne elemente;
c) eno-, dvo- ali tristranske kanale;
d) pritrditve naprav za obešanje (npr. sider) na tleh ali stenah.
