EN 1856-1:2003 (E)3ForewordThis document (EN 1856-1:2003) has been prepared by Technical Committee CEN/TC 166, "Chimneys", thesecretariat of which is held by UNI.This European Standard shall be given the status of a national standard, either by publication of an identical text orby endorsement, at the latest by December 2003, and conflicting national standards shall be withdrawn at the latestby March 2005.This document has been prepared under a mandate given to CEN by the European Commission and the EuropeanFree Trade Association, and supports essential requirements of EU Directive(s).For relationship with EU Directive(s), see informative annex ZA, which is an integral part of this document.Annexes A, B, C and D are normative.According to the CEN/CENELEC Internal Regulations, the national standards organizations of the followingcountries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland,France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal,Slovakia, Spain, Sweden, Switzerland and the United Kingdom.



EN 1856-1:2003 (E)4IntroductionThis European Standard has been prepared to be a harmonised standard to provide means of conforming to the essentialrequirements of the Construction Products Directive and associated EFTA regulations.The generic word "chimney", when used in this standard, refers to systems with metallic liner used to convey the productsof combustion from any appliance to the outside atmosphere, and thus includes all other terms of common use in thetrade, such as: vents, flues, shafts, exhaust systems, ducts, etc.This standard addresses the durability against corrosion by the use of a minimum material specification for the flue liner aswell as an interim solution for testing products for durability against corrosion. Three corrosion resistance tests and theirrequirements have been adopted from existing corrosion testing being undertaken in various member states (see annexA).Is intended to review the interim solution within a period of 5 years with the intention to develop a unique test method fordurability against corrosion as a final solution.This standard describes chimney components, from which system chimneys can be assembled as illustrated in Figure 1.1 ScopeThis standard specifies the performance requirements for single- and multi-wall system chimney products with metallicliners (chimney sections, chimney fittings and terminals, including supports) used to convey the products of combustionfrom 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, areincluded in prEN 1856-2:1996.This standard does not apply to structurally independent (free standing or self-supporting) chimneys.2
