Chimneys - Requirements for metal chimneys - Part 1: System chimney products
This European Standard specifies the performance requirements for single and multi-wall system chimney products with rigid metallic
liners (chimney sections, chimney fittings and terminals, including supports) with nominal diameter up to and including 1200 mm, used
to convey the products of combustion from appliances to the outside atmosphere. It also specifies the requirements for marking,
manufacturer's instructions, product information and evaluation of conformity. Metal liners and metal connecting flue pipes not covered
here are included in EN 1856-2:2009. This European Standard does not apply to structurally independent (free standing or self-supporting) chimneys.
Abgasanlagen - Anforderungen an Metall- Abgasanlagen - Teil 1: Bauteile für System- Abgasanlagen

European foreword
This document (prEN 1856-1:2019) 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 has been prepared under a mandate given to CEN by the European Commission and the
European Free Trade Association.
For relationship with EU Regulation(s), see informative Annex ZA, which is an integral part of this
document.
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";
— adoption of a new revised Annex A "Corrosion tests".

Introduction
The generic word "chimney", when used in this document, refers to systems with metallic liner used to
convey the products of combustion from combustion appliances to the outside atmosphere, and thus
includes all other terms of common use in the trade, such as vents, flues, shafts, exhaust systems, ducts,
etc.
For addressing the durability against corrosion, a unique corrosion test has been introduced in Annex A;
the material table with minimum material specification of the former edition has been taken over.
This document describes chimney components, from which system chimneys can be assembled.

1 Scope
This document specifies the characteristics of performance for single and multi-wall system chimney
products with rigid metal liners (chimney sections, chimney fittings and terminals, including 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. Additionally, it specifies the characteristics for marking, manufacturer's instructions,
product information and assessment and verification of constancy of performance (AVCP). Metal liners
and metal connecting flue pipes not covered here are included in prEN 1856-2:2019.
This document does not apply to structurally independent (free standing or self-supporting) chimneys.
