It supersedes BS EN 1856-1:2003 which is withdrawn. BS EN 1856-1:2003 superseded BS 4543-2:1990 and BS 4
3、543-3:1990, and those requirements and recommendationsrelating to chimneys that were removed from BS 715:1993 . BS 715:1993 was amended and republished as BS 715:2005 leaving only requirements relating to flue boxes.The UK participation in its preparation was entrusted by Technical Committee B/506,
4、Chimneys, to its Subcommittee B/506/5, Chimneys and their components having inner linings of metal.A list of organizations represented on this subcommittee can be obtained on request to its secretary.EN 1856-1 is a candidate “harmonized” European standard and fully takes into account the requirement
5、s of the European Commission mandate M/105, Chimneys, flues and specific products, given under the EU Construction Products Directive (89/106/EEC), and intended to lead to CE marking. The date of applicability of EN 1856-1 as a “harmonized“ European standard, i.e. the date after which this standard
6、may be used for CE marking purposes, is subject to an announcement in the Official Journal of the European Communities.EN 1856-1 is the subject of transitional arrangements agreed under the European Commission mandate. The Member States have agreed a nominal transition period for the co-existence of
7、 EN 1856-1 and their corresponding national standard(s). It is intended that this period will comprise a nominal nine month period during which any required changes to national regulations are to be made, followed by a further nominal twelve month period for the implementation of CE marking. At the
8、end of this co-existence period, the national standard(s) will be withdrawn. In the UK there are no corresponding national standards.Clauses NA.1 to NA.5 of National annex NA (informative) identify the specifications previously required in BS 4543-2:1990, BS 4543-3:1990 and BS 715:1993 for chimneys.
9、 Clause NA.5 identifies the chimney test arrangement and fire-stop recommendations, and Clause NA.6 provides recommendations for chimney ridge terminals under wind load.

This European Standard shall be gi
29、ven the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2009, and conflicting national standards shall be withdrawn at the latest by March 2011. Attention is drawn to the possibility that some of the elements of this document may
30、 be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1856-1:2003. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association,
31、and supports essential requirements of EC Directive 89/106/EEC. For relationship with EC Directive 89/106/EEC, see informative Annex ZA, which is an integral part of this document. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are
32、bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden
33、, Switzerland and the United Kingdom. BS EN 1856-1:2009EN 1856-1:2009 (E) 6 Introduction This European Standard has been prepared to be a harmonised standard to provide means of conforming to the essential requirements of the Construction Products Directive and associated EFTA regulations. The gener
34、ic word “chimney“, when used in this European Standard, refers to systems with metallic liner used to convey the products of combustion from any appliance to the outside atmosphere, and thus includes all other terms of common use in the trade, such as vents, flues, shafts, exhaust systems, ducts, et
35、c. This European Standard addresses the durability against corrosion by the use of a minimum material specification for the flue liner as well as an interim solution for testing products for durability against corrosion. Three corrosion resistance tests and their requirements have been adopted from
36、existing corrosion testing being undertaken in various member states (see Annex A). This European Standard describes chimney components, from which system chimneys can be assembled as illustrated in Figure 1. BS EN 1856-1:2009EN 1856-1:2009 (E) 7 1 Scope This European Standard specifies the performa
37、nce 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.
38、 It also specifies the requirements for marking, manufacturers 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 standin
39、g or self-supporting) chimneys. 2 Normative references The following referenced documents are indispensable for the application of this document.
