Extended application of results from fire resistance tests - Non-loadbearing walls - Part 5: Metal sandwich panel construction

This document defines rules for extended applications, provides guidance, and, where appropriate, defines procedures, for variations of certain parameters and factors associated with the design of internal and external non-loadbearing walls constructed of metal sandwich panels and that have been tested in accordance with EN 1364-1, which could generate a classification in accordance with EN 13501-2.
EN 15254-5 applies for self-supporting, double skin metal faced sandwich panels having an insulating core bonded to both facings as defined in EN 14509.

Erweiterter Anwendungsbereich der Ergebnisse von Feuerwiderstandsprüfungen - Nichttragende Wände - Teil 5: Sandwichelemente in Metallbauweise

Dieses Dokument definiert Regeln für erweiterte Anwendungsbereiche, enthält Leitlinien und legt, falls erforderlich, Verfahren für Änderungen von bestimmten Parametern und Faktoren fest, die mit der Bauweise von nichttragenden Innen- und Außenwänden zusammenhängen, die aus Sandwichelementen in Metallbauweise (im Folgenden als "Sandwichelement" bezeichnet) bestehen und die nach EN 1364-1 geprüft wurden, was zu einer Klassifizierung nach EN 13501-2 führen könnte.
EN 15254-5 gilt für selbsttragende Sandwichelemente mit beidseitigen Metalldeckschichten und einem Kern aus Wärmedämmstoff, der, wie in EN 14509 definiert, mit beiden Deckschichten verklebt ist.

Le présent document définit les règles pour les applications étendues, expose les lignes directrices et, le cas échéant, définit des procédures pour les modifications de certains paramètres et facteurs liés à la conception de murs internes et externes non porteurs en panneaux sandwiches métalliques et qui ont été soumis à essai conformément à l’EN 1364-1, pouvant générer une classification conformément à l’EN 13501-2.
L’EN 15254-5 s’applique aux panneaux sandwiches autoportants, à deux parements métalliques comportant une âme isolante liée aux deux parements métalliques tels que définis dans l’EN 14509.

Ta evropski standard določa pravila za razširjeno uporabo, zagotavlja navodila in po potrebi določa postopke za odstopanja nekaterih parametrov in faktorjev, povezanih z obliko notranjih in zunanjih nenosilnih sten, zgrajenih iz kovinskih sendvič panelov, preskušenih v skladu s standardom EN 1364-1.
Standard EN 15254-5 se uporablja za samonosilne dvoslojne kovinske sendvič panele z izoliranim jedrom, vezanim na obe strani, kot je določeno v standardu EN 14509.
