20、2953-2:2012) has been prepared by Technical Committee CEN/TC 269 “Shell and water-tube 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 or by endorsement, at the latest by September
21、2012, and conflicting national standards shall be withdrawn at the latest by September 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent r
22、ights. This document supersedes EN 12953-2:2002. 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, w
23、hich is an integral part of this document. Annex A provides details of significant technical changes between this European Standard and the previous edition. The European Standard EN 12953 concerning shell boilers consists of the following parts: Part 1: General; Part 2: Materials for pressure parts
24、 of boilers and accessories; Part 3: Design and calculation for pressure parts; Part 4: Workmanship and construction of pressure parts of the boiler; Part 5: Inspection during construction, documentation and marking of pressure parts of the boiler; Part 6: Requirements for equipment for the boiler;
25、Part 7: Requirements for firing systems for liquid and gaseous fuels for the boiler; Part 8: Requirements for safeguards against excessive pressure; Part 9: Requirements for limiting devices of the boiler and accessories; Part 10: Requirements for feedwater and boiler water quality; Part 11: Accepta
26、nce tests; Part 12: Requirements for grate firing systems for solid fuels for the boiler; Part 13: Operating instructions; CR 12953 Part 14: Guideline for involvement of an inspection body independent of the manufacturer. DIN EN 12953-2:2012-05 EN 12953-2:2012 (E) 4 Although these parts may be obtai
27、ned separately, it should be recognized that the parts are interdependent. As such, the design and manufacture of shell boilers requires the application of more than one part in order for the requirements of the European Standard to be satisfactorily fulfilled.
