25、303-1:2017 (E) 4 European foreword This document (EN 303-1:2017) has been prepared by Technical Committee CEN/TC 57 “Central heating boilers”, the secretariat of which is held by DIN. This European Standard shall be given the status of a national standard, either by publication of an identical text
26、or by endorsement, at the latest by March 2018, and conflicting national standards shall be withdrawn at the latest by March 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying a
27、ny or all such patent rights. This document has been prepared under a mandate M/534 and M/535 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 and A
28、nnex ZB, which are integral parts of this document. This document supersedes EN 303-1:1999 and EN 15034:2006. The following essential changes have been made: a) Construction requirements were adopted from EN 15034; b) Terminology of EU-Regulations 811/2013 and 813/2013 adopted; c) the document was c
29、ompletely revised technically; d) the document was completely revised editorially.

BS EN 3031:2017EN 303-1:2017 (E) 5 1 Scope This European Standard applies to boilers used for central heating (heating boilers) with forced draught burners with a nominal heat out
35、put not exceeding 1 000 kW, which are operated either with negative pressure (natural draught boilers) or with positive pressure (pressurized boiler) in the combustion chamber, in accordance with the boiler instructions. This European Standard specifies the necessary terminology, the requirements on
36、 the materials and testing of them, and marking requirements for heating boilers. Particular requirements for boilers that can be used with open vented systems are contained in EN 303-4. The requirements of this standard apply to heating boilers that are tested on an authorized test rig. Boilers in
37、accordance with this standard are designed for the heating of central heating installations in which the heat carrier is water, and the maximum allowable operating temperature of which is restricted to 100 C. The maximum allowable operating pressure is 8 bar. For boilers and water heaters (storage o
38、r continuous flow heater) this standard only applies to the parts which are necessarily subject to the operating conditions of the heating boiler (heating part). This standard does not apply to gas boilers with atmospheric burners, boilers for solid fuels, boilers with oil vaporization burners. For
39、these boilers there are further requirements. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
