This European Standard has been prepared under a mandat

15、e 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 is an integral part of this standard. This European Standard shall be given the status of

16、a national standard, either by publication of an identical text or by endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latest by November 2002. The European Standard EN 12953 concerning shell boilers consists of the following Parts: - Part I:

17、General. - Part 2: Materials for pressure parts 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

18、. - Part 6: Requirements for equipment for the boiler - 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 IO: Require

19、ments for boiler feedwater and boiler water quality. - Part I I: Acceptance tests. - Part 12: Requirements for firing systems for solid fuels for the boiler. - Part 13: Operational instructions. CR 12953-1 4: Guidelines for the involvement of an inspection body independent of the manufacturer. Altho

20、ugh, these Parts can be obtained separately, it should be recognized that the Parts are inter-dependent. As such, the design and manufacture of shell boilers requires the application of more than one Part in order for the requirements of the standard to be satisfactorily fulfilled. According to the

21、CENKENELEC Internal Regulations, the national standards organizations of the following coun- tries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Sp

22、ain, Swe- den, Switzerland and the United Kingdom. 3 EN 12953-512002 (E) 1 Scope This Part of the European Standard specifies requirements for the inspection during construction, documentation and marking of shell boilers as defined in EN 12953-1. 2 Normative references This European Standard incorp

Conformity shall be confirmed by the completion of

33、 a series of inspection activities as given in Table 5.4-1. Depending upon the conformity assessment module chosen by the manufacturer for the design and manufacture of each boiler (see EN 12953-1:2002, Annex B), the inspection activities shall involve, to a greater or lesser extent, or- ganisations

34、 which are independent of the manufacturer. NOTE ties (RA), is described in CR 12953-14.

37、c, magnetic particle examination and/or penetrant testing as specified in 5.5.2 to 5.5.4. Personnel responsible for non-destructive examination, including interpretation, evaluation and reporting shall be cer- tified in accordance with EN 473. An exception to this requirement shall be made for visua

38、l examination of welds and final inspection of boilers, for which EN 473 is not applicable. Visual examination shall be in accordance with EN 970. Visual examination shall be carried out by experienced personnel having sufficient knowledge in welding techniques, and a full comprehension of this Euro
