(Main)Fire resistance tests for service installations - Part 1: Ventilation ducts
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.

According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,

Introduction
The purpose of this test is to measure the ability of a representative ventilation duct assembly / system
that is part of an air distribution system to resist the spread of fire from one fire compartment to
another with fire attack from inside or outside the duct. It is applicable to vertical and horizontal ducts,
with or without branches, taking into account joints and openings, as well as suspension devices and
penetration points.
The test measures the length of time for which ducts, of specified dimensions, suspended as they would
be in practice, satisfy defined criteria when exposed to fire from (separately) both inside and outside
the duct.
The closed end of each horizontal duct at the back of the furnace is fully restraint. Outside the furnace,
ducts exposed to fire from the outside are tested unrestrained, while ducts exposed to fire from the
inside (horizontal only) are tested restrained.
The force measurement at horizontal duct B is not mandatory but can be done on the request of the
sponsor.
The test takes into account the effect of fire exposure from the outside where a pressure differential is
maintained in the duct as well as the effect of fire entering the ducts in conditions where forced air
movement may or may not be present.
Caution
The attention of all persons concerned with managing and carrying out this fire resistance test is drawn
to the fact that fire testing may be hazardous and that there is a possibility that toxic and/or harmful
smoke and gases may be evolved during the test. Mechanical and operational hazards may 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.

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;
