Free-standing chimneys - Part 1: General requirements

This document deals with the general requirements and the basic performance criteria for the design and construction of all types of structurally independent chimneys including their liners.
This document also applies to chimneys connected to buildings when at least one of the following criteria is met:
-   the distance between the lateral guides is more than 4 m;
-   the free-standing height above the uppermost structural support attachment is more than 3 m;
-   the free-standing height above the uppermost structural support attachment for chimneys with rectangular cross section is more than five times the smallest external dimension.
Structurally independent chimneys take into account in their design: operational conditions and other actions to verify mechanical resistance and stability and safety in use. Detailed requirements relating to specialized designs are given in the standards for concrete chimneys, steel chimneys and their liners, as well as masts construction with satellite components.
In other parts of the EN 13084 series, rules will be given where system chimney products in accordance with EN 1443 (and the relating product standards) are used in structurally independent chimneys.
This document does not cover the design and construction of connecting flue pipes.

Freistehende Schornsteine - Teil 1: Allgemeine Anforderungen

Dieses Dokument behandelt die allgemeinen Anforderungen und die Grundkriterien für Entwurf, Berechnung und Konstruktion aller Arten von freistehenden Abgasanlagen, einschließlich deren Innenrohre.
Dieses Dokument ist auch anwendbar auf mit Gebäuden verbundene Schornsteine, wenn mindestens eines der folgenden Kriterien erfüllt wird:
-   der Abstand zwischen den seitlichen Führungen ist größer als 4 m;
-   die freistehende Höhe über der obersten statisch wirksamen Abstützung ist größer als 3 m;
-   die freistehende Höhe über der obersten statisch wirksamen Abstützung bei Schornsteinen mit einem rechtwinkligen Querschnitt beträgt mehr als das Fünffache des kleinsten Außenmaßes.
Bei der Bemessung von freistehenden Abgasanlagen werden die Betriebsbedingungen und sonstige Einwirkungen berücksichtigt, um die mechanische Festigkeit, Standsicherheit und Nutzungssicherheit nachzuweisen. Detaillierte Anforderungen bezüglich der einzelnen Konstruktionsarten werden in den Normen für Betonschornsteine, Stahlschornsteine und deren Innenrohre sowie Tragmastkonstruktionen mit angehängten Abgasanlagen gegeben.
Regeln für die Verwendung von System-Abgasanlagenprodukten nach EN 1443 (und der damit verbundenen Produktnormen) in freistehenden Abgasanlagen werden in anderen Teilen von EN 13084 angegeben.
Dieses Dokument ist nicht anwendbar auf die Bemessung und Konstruktion von Verbindungsstücken.

Cheminées autoportantes - Partie 1 : Exigences générales

Le présent document traite des exigences générales et des critères de performances fondamentaux concernant la conception et la réalisation de tous les types de cheminées autoportantes, y compris leur conduit intérieur.
Le présent document s’applique également aux cheminées attachées aux bâtiments lorsqu’au moins l’un des critères suivants est respecté :
-   la distance entre les guides latéraux est supérieure à 4 m ;
-   la hauteur autoportante au-dessus de la fixation la plus haute des supports à la structure est supérieure à 3 m ;
-   la hauteur libre au-dessus de la fixation la plus haute des supports à la structure pour les conduits de fumée avec section rectangulaire est supérieure à cinq fois la plus petite dimension extérieure.
La conception des cheminées autoportantes tient compte de ce qui suit : les conditions d’opération et d’autres effets pour vérifier la résistance mécanique, la stabilité et la sécurité d’utilisation. Des exigences détaillées relatives aux conceptions particulières sont fournies dans les normes pour cheminées en béton, cheminées en acier et conduits intérieurs, ainsi que pour conception des mâts intégrant des conduits systèmes métalliques.
D’autres parties de la série de normes EN 13084 énoncent des règles selon lesquelles des produits de conduits de fumée conformément à l’EN 1443 (et aux normes de produits associées) sont utilisés dans des cheminées autoportantes.
Le présent document ne couvre pas la conception et la construction des conduits de raccordement.
