Chimneys - Requirements for metal chimneys - Part 1: System chimney products

This document specifies the characteristics of performance for single and multi-wall system chimneys with rigid metal liners composed of chimney sections, chimney fittings, terminals and supports with nominal diameter up to and including 1 200 mm, used to convey the products of combustion from appliances to the outside atmosphere.
This document also specifies characteristics for the air supply ducts of concentric chimneys for room-sealed application, made out of metal or plastic (without fibre stabilization).
Additionally, it specifies assessment and verification of constancy of performance (AVCP).
NOTE 1   Metal liners and metal connecting flue pipes, not covered, are included in prEN 1856-2:2021.
NOTE 2   This document does not apply to structurally independent chimneys.

Abgasanlagen - Anforderungen an Metall-Abgasanlagen - Teil 1: Bauteile für System-Abgasanlagen

Dieses Dokument legt die Leistungsmerkmale für ein- und mehrschalige System-Abgasanlagen mit starren Metallinnenrohren fest, die aus Abschnitten, Formstücken, Aufsätzen und Stützen der Abgasanlagen bestehen, die über einen Nenndurchmesser von bis zu 1 200 mm verfügen und zur Ableitung von Verbrennungsprodukten von Feuerstätten an die Außenluft verwendet werden.
Dieses Dokument legt auch Eigenschaften für die Zuluftleitungen von konzentrischen Abgasanlagen für raumluftunabhängige Anwendung aus Metall oder Kunststoff (ohne Faserverstärkung) fest.
Zusätzlich spezifiziert es die Bewertung und Überprüfung der Leistungsbeständigkeit ― AVCP (en: Assessment and verification of constancy of performance).
ANMERKUNG 1   Innenrohre und Verbindungsstücke aus Metall, die in dieser Norm nicht behandelt werden, sind in EN 1856-2:2021 aufgeführt.
ANMERKUNG 2   Dieses Dokument gilt nicht für freistehende Abgasanlagen.

Conduits de fumée - Prescriptions pour les conduits de fumée métalliques - Partie 1 : Composants de systèmes de conduits de fumée

Le présent document spécifie les caractéristiques de performance des systèmes de conduits de fumée avec conduits intérieurs métalliques rigides simple paroi ou multi-parois qui sont composés d’éléments droits, d’éléments de raccordement du conduit de fumée, de terminaux et de supports, d'un diamètre nominal jusqu'à 1 200 mm inclus, utilisés pour évacuer les produits de combustion des appareils jusqu'à l'atmosphère extérieure.
Ce document spécifie aussi les caractéristiques des conduits d'alimentation en air des conduits de fumée concentriques pour les applications à circuit étanche, en métal ou en plastique (sans stabilisation de fibre).
Il spécifie également l’évaluation et la vérification de la constance des performances (EVCP).
NOTE 1   Les conduits intérieurs et les conduits de raccordement métalliques qui ne sont pas traités ici font l'objet du prEN 1856-2:2021.
NOTE 2   Le présent document ne s'applique pas aux conduits de fumée structurellement indépendants.
