Fire resistance tests for service installations - Part 3: Penetration seals
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. 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. Explanatory notes to this test method are given in Annex H. All dimensions given without tolerances are nominal ones unless otherwise stated.
Feuerwiderstandsprüfungen für Installationen - Teil 3: Abschottungen
Dieser Teil der EN 1366 legt ein Prüfverfahren und die Kriterien für die Beurteilung der Eignung eines Abschottungssystems, den Feuerwiderstand eines raumabschließenden Bauteils an der Stelle aufrechtzu-erhalten, durch die eine Installation geleitet wird, fest. Abschottungssysteme für Zwischenräume und Öffnungen um Kamine, Lüftungssysteme, Lüftungsleitungen, Installationskanäle und -schächte sowie Entrauchungsleitungen mit definierter Feuerwiderstandsdauer sind von dieser Norm ausgenommen.
In dieser Norm werden Tragkonstruktionen stellvertretend für raumabschließende Bauteile, wie zum Beispiel Wände und Decken, verwendet. Diese stellen die Wechselwirkungen zwischen Probekörper und dem raumabschließenden Bauteil, in welchen das Abschottungssystem in der Praxis eingebaut werden soll, nach.
Diese Norm gilt zusammen mit EN 1363-1.
Die in dieser Norm beschriebene Prüfung dient der Beurteilung
a) der Auswirkung derartiger Durchführungen auf das raumabschließende und wärmedämmende Verhalten des betreffenden raumabschließenden Bauteils;
b) des Raumabschlusses und Wärmedämmverhaltens des Abschottungssystems;
c) des Wärmedämmverhaltens der durchlaufenden Installation(en) und erforderlichenfalls des Verlustes der raumabschließenden Wirkung einer Installation.
Die Prüfung ermöglicht keine Aussagen darüber, inwieweit das Vorhandensein derartiger Durchführungen und Abschottungssysteme einen Einfluss auf die Tragfähigkeit des raumabschließenden Bauteils ausübt.
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 sollten nur bei der Beschreibung des allgemeinen Verhaltens der Probekörper während der Prüfung festgehalten werden.
Diese Prüfung liefert keine Angaben über das Leistungsverhalten eines Abschottungssystems, Spannungen, die durch Bewegungen oder Verschiebungen der durchlaufenden Installationen erzeugt werden(...)
Essais de résistance au feu des installations techniques - Partie 3 : Calfeutrements de trémies
La présente partie de l'EN 1366 spécifie une méthode d'essai et des critères pour l'évaluation (ainsi que des règles de domaine d'application) de l'aptitude d'un calfeutrement à maintenir la résistance au feu d'un élément séparatif à l'endroit auquel il est traversé par un traversant. Les calfeutrements de trémie utilisés pour combler les espaces autour des cheminées, les systèmes de ventilation, les conduits de ventilation classés au feu, les gaines pour traversants classées au feu et les conduits d'extraction de fumée sont exclus de la présente norme, sauf les calfeutrements de trémie mixtes. La résistance au feu intrinsèque de ces traversants ne peut pas être évaluée selon les méthodes de la présente norme.
Les constructions support sont utilisées dans la présente norme pour représenter les éléments séparatifs comme les parois ou les planchers. Elles simulent l'interaction entre l'éprouvette et l'élément séparatif dans lequel le système de calfeutrement sera installé dans les conditions réelles.
La présente norme est utilisée en association avec l'EN 1363-1.
L'objet de cet essai décrit dans la norme est d'évaluer :
a) l’effet de ces trémies sur l’étanchéité au feu et l’isolation de l’élément séparatif concerné ;
b) l’étanchéité au feu et l’isolation du calfeutrement de trémie ;
c) l’isolation du/des traversant(s), et le cas échéant, la perte d’étanchéité au feu d’un traversant.
Aucune information ne peut être déduite de l'essai en ce qui concerne l'incidence de l'intégration de ces trémies et de ces systèmes de calfeutrement sur la capacité portante de l'élément séparatif.
Cet essai n'a pas pour but de fournir des informations quantitatives sur le taux d'étanchéité aux fumées et/ou aux gaz, ou sur la transmission de gaz chauds ou la génération de fumées. Ces phénomènes ne sont à prendre en compte que dans la description du comportement général des éprouvettes durant l'essai.
Cet essai n'a pas pour but de 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 à travers un tuyau vers les étages inférieurs ne peut pas être évalué par le présent essai.
Des notes explicatives de cette méthode d'essai figurent en Annexe H.
Toutes les dimensions indiquées sans tolérances sont nominales, sauf indication contraire.

EN 1366-3:2009 (E) 3 Introduction This part of this European Standard 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 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. SIST EN 1366-3:2009
