National foreword This standard has been prepared by Technical Committee CEN/TC 57 “Central heating boilers” (Secretariat: DIN, Germany). The responsible

6、German body involved in its preparation was the Normenausschuss Heiz- und Raumluft-technik (Heating and Ventilation Technology Standards Committee), Working Committee NA 041-01-62 AA Zentralheizungskessel (SpA CEN/TC 57). As regards emission limits, Germany had requested that an A-deviation be appli

7、ed for Germany because emission limits are regulated in Chapter 2, paragraphs 4 and 5, and Annex 2 of the German Immission Control Ordinance “Erste Verordnung zur Durchfhrung des Bundes-Immissionsschutzgesetzes (Verordnung ber kleine und mittlere Feuerungsanlagen - 1. BImSchV)”. This A-deviation is

8、given in Annex C. Other countries had also requested an A-deviation, namely Austria, Croatia, Denmark, Switzerland, the United Kingdom and Italy. These A-deviations are also given in Annex C. Amendments This standard differs from DIN EN 303-5:1999-06 as follows: a) the scope has been extended to a n

9、ominal heat output of the heating boilers for 500 kW; b) usable fuel to non-wood biomass and further solid fuels have been extended; c) requirements for materials, weld joints and wall thicknesses have been revised; d) risk analysis has been implemented; e) general and electrical safety requirements

10、 have been revised; f) emission class 1 and 2 have been deleted and new emission class 4 and 5 have been added; g) tests have been revised and new tests for safety requirements have been added; h) annexes have been re-structured; i) consideration has been given to the essential requirements of the M
