Extended application of results from fire resistance tests for service installations - Part 2: Fire dampers
This European Standard provides guidance and rules to notified bodies (for fire dampers) to allow them to produce/validate an extended field of application report for fire dampers. This standard identifies the parameters that affect the fire resistance of dampers. It also identifies the factors that need to be considered when deciding whether, or by how much, the parameter can be extended when contemplating the fire resistance performance of an untested, or untestable variation in the construction.
This European Standard explains the principles behind how a conclusion on the influence of specific parameters/constructional details relating to the relevant criteria (E,I,S) can be achieved.
This European Standard does not cover dampers used for smoke control.
This European Standard only applies to extended fields of application based on tests successfully undertaken to EN 1366-2. Only test reports that have a total test time where the criteria are fulfilled that is in excess of the required classification period by a margin of either 10 % or 12 min, whichever is the least, are to be considered. Each classification (E,I,S) is to be considered individually - consequently E (134 min achieved) may be extended, but EI (61 min achieved) may not be extended for a classification of EI60.
Additionally, leakage determined during such tests is to be at least 10 % below the leakage limits for E, or for E-S, dependent on classification achieved, given in EN 13501-3 before the EXAP rules can be applied. The 10 % below the leakage limits is to be fulfilled for the extended period in addition to the classification period.
By application of this European Standard, it should be possible to identify what specifications should be tested to maximize the field of application. Some information on test programmes is given for guidance purposes.
Erweiterter Anwendungsbereich der Ergebnisse aus Feuerwiderstandsprüfungen für Installationen - Teil 2: Brandschutzklappen
Diese Europäische Norm legt eine Anleitung und Regeln für notifizierte Stellen (für Brandschutzklappen) in Bezug auf die Erstellung/Überprüfung von Berichten zum erweiterten Anwendungsbereich für Brandschutzklappen fest. Diese Norm benennt die Parameter, die die Feuerwiderstandsfähigkeit von Brandschutzklappen beeinflussen. Sie benennt auch die Faktoren, die bei der Entscheidung zu berücksichtigen sind, ob oder bis zu welchem Ausmaß ein Parameter bei der Betrachtung der Feuerwiderstandsfähigkeit einer ungeprüften oder unprüfbaren Abweichung einer Konstruktion erweitert werden kann.
Diese Europäische Norm legt die Grundsätze dar, die eine Schlussfolgerung über den Einfluss von speziellen Parametern/Konstruktionsdetails, welche die entsprechenden Kriterien (E, I, S) betreffen, ermöglichen.
Diese Europäische Norm gilt nicht für Brandschutzklappen, die zur Entrauchung verwendet werden.
Diese Europäische Norm gilt nur für erweiterte Anwendungsbereiche, die auf erfolgreichen Prüfungen nach EN 1366 2 basieren. Zu berücksichtigen sind nur diejenigen Prüfberichte, bei denen die Gesamtprüfzeit, während der die Leistungskriterien erfüllt werden, die angestrebte Klassifizierungszeit um eine Spanne von 10 % oder 12 min überschreitet, wobei der kleinere Wert für die Spanne maßgebend ist. Jede Klassifizierung (E, I, S) muss einzeln betrachtet werden — folglich darf E (134 min erreicht) erweitert werden, während EI (61 min erreicht) bei einer Klassifizierung von EI 60 nicht erweitert werden darf.
Des Weiteren müssen die in den betreffenden Prüfungen bestimmten Leckagewerte abhängig von der erzielten Klassifizierung mindestens 10 % unterhalb der in EN 13501 3 angegebenen Leckagegrenzen für E bzw. E-S liegen, um die Regeln für die Erweiterung des Anwendungsbereiches anwenden zu können. Der Wert von 10 % unterhalb der Leckagegrenze muss zusätzlich zur Klassifizierungszeit über den längeren Zeitraum eingehalten werden.
Durch Anwendung dieser Europäischen Norm sollte es möglich sein, zu erkennen, welche Spezifikationen geprüft werden sollten, um den Anwendungsbereich soweit wie möglich zu erweitern. Einige Informationen über Prüfprogramme sind zur Anleitung aufgeführt.
Application étendue des résultats des essais de résistance au feu des installations de service - Partie 2 : Clapets résistant au feu
La présente Norme européenne fournit des conseils et des règles aux organismes notifiés (pour les clapets résistant au feu) afin de leur permettre d’élaborer/de valider un rapport de domaine d’application étendue pour ces clapets. La présente norme identifie les paramètres qui ont une incidence sur la résistance au feu des clapets. Elle identifie également les facteurs devant être pris en considération lorsqu’il s’agit de décider si, ou dans quelle mesure, un paramètre peut être étendu, en examinant la résistance au feu d’une variation non soumise à essai ou ne pouvant pas être soumise à essai dans la construction.
La présente Norme européenne explique les principes permettant d’arriver à une conclusion concernant l’influence de paramètres/détails de construction spécifiques pour les critères pertinents (E, I, S).
La présente Norme européenne ne couvre pas les volets de désenfumage.
La présente Norme européenne s’applique uniquement aux domaines d’application étendue reposant sur des essais réalisés avec succès selon l’EN 1366-2. Il convient de ne prendre en considération que les rapports d’essai qui mentionnent une durée d’essai totale pendant laquelle les critères sont remplis qui est supérieure au temps de classement requis avec une marge de 10 % ou de 12 min, en retenant la plus petite de ces deux valeurs. Il convient que chaque classement (E, I, S) soit pris en compte séparément – par conséquent, le critère E (obtention d’un temps de 134 min) peut être étendu, tandis que les critères EI (obtention d’un temps de 61 min) peuvent ne pas l’être pour un classement EI60.
En outre, il convient que les fuites déterminées lors de ces essais soient au moins inférieures de 10 % aux limites de fuite pour E ou pour E-S, suivant le classement obtenu, indiquées dans l’EN 13501 3 avant de pouvoir appliquer les règles d’EXAP. Il convient que cette valeur inférieure de 10 % aux limites de fuite soit atteinte pendant la période étendue qui vient s’ajouter au temps de classement.
L’application de la présente Norme européenne devrait permettre d’identifier quelles spécifications il convient de contrôler pour optimiser le domaine d’application. Certaines informations relatives aux programmes d’essai sont fournies à titre de recommandations.

Introduction It should be noted that fire-resisting dampers are special products that are exposed to different conditions to other elements of construction; in particular they are subjected to significantly different pressure regimes. Also, integrity is evaluated by leakage measurements. Consequently, this European Standard may adopt a different approach to other extended field of application standards, with more emphasis on testing. SIST EN 15882-2:2015

3 Terms and definitions For the purposes of this document, the terms and definitions given in EN 1363-1 and EN 1366-2 and the following apply. 3.1 multiple section assemblies assemblies of individual damper units to form larger units 3.2 horizontal orientation of damper position of the damper mounted horizontally EXAMPLE When installed in the plane of a floor or a ceiling. 3.3 vertical orientation of damper position of the damper mounted vertically, e.g. when installed in the plane of a wall 3.4 supporting construction construction used as part of the test assembly to support the test specimen and to fill in the furnace aperture 3.5 standard supporting construction supporting construction that has known fire behaviour and for which a Direct Field of Application has been established 4 Determination of worst case In certain circumstances a rule can call for a new test to be undertaken. To avoid having to re-test everything, a determination shall be made of 'worst case'. Firstly consider the classification required: E, EI, E-S, EI-S. Consider all the test reports that give the required classification. Determine which criteria failed first in each test. The resulting 'worst case' will be the one where the time to failure of each and any of the parameters was the lowest. If the test periods show that none of the criteria failed before the classification period plus 10 % or 12 min, then the supporting construction shall be considered. The worst case shall be with the fire damper mounted in the lightest construction in terms of mechanical stability. The sponsor may pick a heavier supporting construction, but then any extended field of applications shall only apply to this supporting construction and those heavier and more dense as per direct field of application. The method of determination of worst case and the related extended fields of application shall be reported in the extended field of application report. 5 Conditions and application rules 5.1 Change of fixing damper to supporting construction a) No change in the location of the fixings relative to the damper and the supporting construction shall be permitted. The pitch between the fixings shall not be increased. SIST EN 15882-2:2015
b) Alternative fixings may be used if their performance is proven by fire test, stress, linear expansion and loading information data. Any other information available may be considered. c) Any alternative fixings shall be included as part of the extended field of application report. d) Hanger and relating anchor information shall be assessed in accordance with EN 15882-1. 5.2 Multiple damper assemblies 5.2.1 E Classification only 5.2.1.1 Method To allow the use of multiple assemblies of E classified fire dampers, either side by side or on top of each other, the following test shall be performed. An assembly consisting of fire dampers that have already successfully gained a classification conforming to EN 13501-3 shall be made and installed into a supporting construction using the proposed method. A fire damper selected using the worst case method in accordance with Clause 4 shall be made into an assembly as shown in Figure 1. This will allow the other EXAP rules from the tables which follow to apply to multi-section units, as they do to single section units. The unit to be tested shall be constructed so as to be made up of at least four sections and shall have a maximum overall size of 2 600 mm × 2 600 mm. This is to allow for a small gap around the outside of the damper and a minimum span of supporting construction of 200 mm all round. See Figure 1 which is applicable to both vertical (shown) and horizontal test installations. The test method shall be generally as EN 1366-2 (note: also refer to intumescent fire damper test, if this becomes relevant), but instead of a closed plenum with a fan, an extended open duct 1 m long shall be fixed to the dampers.
