(Main)Fire resistance tests for service installations - Part 3: Penetration seals
Fire resistance tests for service installations - Part 3: Penetration seals
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.
Feuerwiderstandsprüfungen für Installationen - Teil 3: Abschottungen
Essais de résistance au feu des installations techniques - Partie 3: Calfeutrement des trémies
La présente partie de la série EN 1366 spécifie une méthode d’essai et des critères pour l’évaluation (incluant des règles de domaine d’application directe) de l’aptitude d’un calfeutrement de trémie à maintenir la résistance au feu d’un élément séparatif à l’endroit auquel il est traversé par un ou plusieurs traversants. Les calfeutrements de trémies utilisés pour combler les espaces autour des cheminées, des systèmes de ventilation, des gaines de ventilation classées au feu, des gaines pour traversants classées au feu et des gaines d’extraction de fumée sont exclus du domaine d’application de la présente partie de la série EN 1366, de même que les calfeutrements de trémies combinés.
NOTE L’EN 15882-5 [6] traite des calfeutrements de trémies, y compris les gaines et les clapets.
Des constructions support sont utilisées dans la présente partie de la série EN 1366 pour représenter les éléments séparatifs tels que les murs ou les planchers. Elles simulent l’interaction entre l’élément d’essai et l’élément séparatif dans lequel le système de calfeutrement doit être installé dans les conditions réelles.
La présente partie de la série EN 1366 est destinée à être utilisée conjointement avec l’EN 1363 1.
L’objet des essais décrits dans la présente partie de la série EN 1366 est d’évaluer l’étanchéité au feu et la performance d’isolation du calfeutrement de trémie, du ou des traversants et de l’élément séparatif dans la zone environnante du calfeutrement.
Aucune information ne peut être déduite de l’essai en ce qui concerne l’incidence de l’intégration de ces trémies et de ces calfeutrements de trémies sur la capacité portante de l’élément séparatif.
Dans chaque cas, le linteau situé au-dessus d’un calfeutrement de trémie dans la paroi est présumé conçu à l’état chaud et froid de sorte qu’il n’applique aucune charge verticale supplémentaire sur le calfeutrement.
Cet essai n’a pas pour but de fournir des informations quantitatives sur le taux d’étanchéité aux fumées et/ou aux gaz chauds, ou sur la transmission de gaz chauds ou la génération de fumées. Ces phénomènes sont uniquement consignés dans le rapport d’essai qui décrit le comportement général des éléments au cours de l’essai.
Les essais réalisés conformément à la présente partie de la série EN 1366 ne sont pas destinés à 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, par exemple, à travers un tuyau vers les étages inférieurs, est actuellement exclu du présent document.
Les essais effectués conformément à la présente partie de la série EN 1366 ne couvrent pas les risques associés aux fuites de liquides ou de gaz dangereux dues à la rupture de tuyaux en cas d’incendie.
Les essais réalisés conformément à la présente partie de la série EN 1366 sur des calfeutrements de trémies pour des tuyaux de systèmes de distribution pneumatiques, de systèmes d’air sous pression, etc. simulent une situation où ces systèmes sont coupés en cas d’incendie.
Des notes explicatives de cette méthode d’essai figurent à l’Annexe H.
Sauf spécification contraire, toutes les valeurs indiquées sans tolérances dans le présent document sont des valeurs nominales.
Tous les diamètres de tuyaux sont des diamètres externes, sauf spécification contraire.
