This European Standard shall be given the status of

18、a national standard, either by publication of an identical text or by endorsement, at the latest by September 2012, and conflicting national standards shall be withdrawn at the latest by September 2012.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 subje

19、ct of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 12953-1:2002. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports

20、 essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this document. Annex D provides details of significant technical changes between this European Standard and the previous edition. The European Standard EN 12953 c

24、ndependent of the manufacturer. Although these parts may be obtained 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

25、 satisfactorily fulfilled.

DIN EN 12953-1:2012-05 EN 12953-1:2012 (E) 5 1 Scope 1.1 General This European Standard applies to shell boilers with volumes in excess of 2 litres for the generation of steam and/or hot water at a maximum allowable

28、pressure greater than 0,5 bar and with a temperature in excess of 110 C. The purpose of this European Standard is to ensure that the hazards associated with the operation of shell boilers are reduced to a minimum and that adequate protection is provided to contain the hazards that still prevail when

29、 the shell boiler is put into service. This protection will be achieved by the proper application of the design, manufacturing, testing and inspection methods and techniques incorporated in the various parts of this European Standard. Where appropriate, adequate warning of residual hazards and the p

30、otential for misuse are given in the training and operating instructions and local to the equipment concerned (see EN 12953-7 and EN 12953-8). It is the manufacturers responsibility, in addition to complying with the requirements of this standard, to take into consideration special measures which co

31、uld be necessary in order to achieve by manufacturing the required level of safety in accordance with the EU Directive 97/23/EC (PED). NOTE 1 Further requirements relating to operating instructions in EN 12953-13 and to hazard analysis in CEN/TS 764-6 should be taken into consideration. This Europea

32、n Standard specifies requirements for both directly fired and electrically heated boilers including Low Pressure Boilers (LPB, see 3.6) as well as for heat recovery boilers with a gas-side pressure not exceeding 0,5 bar of cylindrical design, constructed from carbon or carbon manganese steels by fus

33、ion welding and a design pressure not exceeding 40 bar. The boilers covered by this European Standard are intended for land use for providing steam or hot water (typical examples are shown in Figures 1 to 6). For Low Pressure Boilers (LPB) less stringent requirements concerning design and calculatio

34、n are acceptable. Details are defined in the respective clauses. NOTE 2 For boilers operating at a pressure on the gas-side greater than 0,5 bar the rules of this standard equally apply. However, it is generally considered that additional design analysis, inspection and testing may be necessary. Whe

35、re a particular boiler is a combination of shell and water-tube design then the water-tube standard series EN 12952 is used in addition to this European Standard. One such example of this combination is shown in Figure 3. This European Standard applies to the generator, from the feed-water or water

36、inlet connection to the steam or water outlet connection and to all other connections, including the valves and steam and water fittings. If welded ends are used, the requirements specified herein begin or end at the weld where flanges, if used, would have been fitted. 1.2 Exclusions This European s

37、tandard does not apply to the following types of boilers and equipments: a) water-tube boilers; b) non stationary boilers, e.g. locomotive boilers; c) thermal oil boilers; d) boilers where the main pressure housing is made of cast material. e) pumps, gaskets, etc. DIN EN 12953-1:2012-05 EN 12953-1:2
