This Euro
23、pean Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by September 2007, and conflicting national standards shall be withdrawn at the latest by September 2007.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
24、to CEN by the European Commission and the European Free 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. According to the CEN/CENELEC Internal Regulations, the natio

26、oland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United 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
27、 with associated test methods and test fuels for type testing residential slow 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 dec
28、lared period of time after the fire has gone out. This European Standard also specifies 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. Th
29、ese slow heat release appliances may be supplied either as an assembled appliance 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.
30、 These appliances may burn either solid mineral fuels, peat briquettes, natural 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
31、basket arrangement which is placed by the user into the existing firebox. This 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
