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.

European foreword
This document (prEN 1856-1:2021) has been prepared by Technical Committee CEN/TC 166
“Chimneys”, the secretariat of which is held by ASI.
This document is currently submitted to the CEN Enquiry.
This document will supersede EN 1856-1:2009, EN 1859:2009+A1:2013, EN 14989-1:2007 and
EN 14989-2:2007.
The main changes to EN 1856-1:2009 are:
— adoption of the template for harmonized standards under the EU Construction Products Regulation
(305/2011/EU) meaning a clearer definition of the Scope, rewording in Clause 4 “Product
characteristics”, Clause 5 “Testing, assessment and sampling methods” and Clause 7 “Product
classification and designation”, and adoption of the template for Clause 6 “Assessment and
verification of constancy of performance”;
— the main test references are made to EN 13216-1:2019 and the metal chimney specific tests of
EN 1859:2009+A1:2013, and the terminal specific tests of EN 14989-1:2007 and EN 14989-2:2007
have been incorporated into this document;
— adoption of a new revised Annex A “Corrosion tests”. The material table with minimum material
specification of the former edition has been taken over;
— deletion of Annex E, as reference is made to the calculation method of EN 13384-1:2015+A1:2019,
Annex A throughout the document.
This document has been prepared under a standardization request given to CEN by the European
Commission and the European Free Trade Association, and supports essential requirements of EU
Regulation(s).
For relationship with EU Regulation(s), see informative Annex ZA, which is an integral part of this
document.
