1、BRITISH STANDARD BS EN 15250:2007 Slow heat release appliances fired by solid fuel Requirements and test methods The European Standard EN 15250:2007 has the status of a British Standard ICS 97.100.30 ? BS EN 15250:2007 This British Standard was published under the authority of the Standards Policy a
2、nd Strategy Committee on 30 April 2007 BSI 2007 ISBN 978 0 580 50484 6 National foreword This British Standard was published by BSI. It is the UK implementation of EN 15250:2007. The UK participation in its preparation was entrusted to Technical Committee RHE/28, Domestic solid mineral fuel applianc
3、es. A list of organizations represented on RHE/28 can be obtained on request to its secretary. EN 15250 is a candidate “harmonized” European standard and fully takes into account the requirements of the European Commission mandate M/129 “Space heating appliances”, given under the EU Construction Pro
4、ducts Directive (89/106/EEC), and intended to lead to CE marking. The date of applicability of EN 15250 as a harmonized European standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an announcement in the Official Journal of the European Communities. T
5、he Commission in consultation with Member States has agreed a transition period for the co-existence of harmonized European Standards and their corresponding national standard(s). It is intended that this period will comprise a period, usually nine months, after the date of availability of the Europ
6、ean Standard, during which any required changes to national regulations are to be made, followed by a further period, usually of 12 months, for the implementation of CE marking. At the end of this co-existence period, the national standard(s) will be withdrawn. In the UK, there are no corresponding
7、national standards. This publication does not purport to include all the necessary provisions of a contract. Users are responsible for its correct application. Compliance with a British Standard cannot confer immunity from legal obligations. Amendments issued since publication Amd. No. DateComments

This European Standard shall be given the status of a national standard, either by publi
25、cation of an identical text or by endorsement, at the latest by September 2007, and conflicting national standards shall be withdrawn at the latest by September 2007. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and
26、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.

27、his 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, Switzerland and Un
28、ited Kingdom. EN 15250:2007 (E) 5 1 Scope This European Standard specifies requirements relating to the design, manufacture, construction, safety and performance (efficiency and emission) instructions and marking together with associated test methods and test fuels for type testing residential slow
29、heat release appliances fired by solid fuel. This European Standard is applicable to hand fuelled intermittent burning slow heat release appliances having thermal storage capacity such that they can provide heat for a declared period of time after the fire has gone out. This European Standard also s
30、pecifies a minimum time period from the appliance achieving the maximum differential surface temperature and falling to 50 % of that maximum value. These appliances provide heat into the space where they are installed. These slow heat release appliances may be supplied either as an assembled applian
31、ce or as a manufacturers pre-designed unit consisting of pre-fabricated components designed to be built on site in accordance with the manufacturers specified assembly instructions. One off installations are not included. These appliances may burn either solid mineral fuels, peat briquettes, natural
32、 or manufactured wood logs or be multi-fuel in accordance with the appliance manufacturers instructions. Wood pellets which are hand fuelled may also be burned either on the existing appliance bottomgrate or in a special basket arrangement which is placed by the user into the existing firebox. This
33、European Standard is not applicable to mechanically fed appliances, appliances having fan assisted combustion air or appliances with boiler. 2 Normative references The following referenced documents are indispensable for the application of this document.
