This document has been prepared under a mandate given 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

EN 15250:2007 (E) 5 1 Scope This European Standard specifies requirements relating to the design, manufactur
29、e, construction, safety and performance (efficiency and emission) instructions and marking together 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 slo
30、w 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 specifies a minimum time period from the appliance achieving the maximum differential surface temperature and falling to 50
31、 % 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 appliance or as a manufacturers pre-designed unit consisting of pre-fabricated components designed to be built on site in accorda
32、nce with the manufacturers specified assembly instructions. One off installations are not included. 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 whic
33、h 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 European Standard is not applicable to mechanically fed appliances, appliances having fan assisted combustion air or appli
