EN 12953-5:2002 (E)3ForewordThis document (EN 12953-5:2002) has been prepared by Technical Committee CEN/TC 269 "Shell and water-tubeboilers", the secretariat of which is held by DIN.This European Standard has been prepared under a mandate given to CEN by the European Commission and theEuropean 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 a national standard, either by publication of an identical text orby endorsement, at the latest by November 2002, and conflicting national standards shall be withdrawn at the latestby November 2002.The European Standard EN 12953 concerning shell boilers consists of the following Parts: Part 1:General.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. 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 10:Requirements for boiler feedwater and boiler water quality. Part 11:Acceptance tests. Part 12:Requirements for firing systems for solid fuels for the boiler. Part 13:Operational instructions.CR 12953-14:Guidelines for the involvement of an inspection body independent of the manufacturer.Although, these Parts can be obtained separately, it should be recognized that the Parts are inter-dependent. Assuch, the design and manufacture of shell boilers requires the application of more than one Part in order for therequirements of the standard to be satisfactorily fulfilled.According to the CEN/CENELEC 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, Spain, Swe-den, Switzerland and the United Kingdom.SIST EN 12953-5:2002

Conformity shall be confirmed by the completion of 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 ofeach boiler (see EN 12953-1:2002, Annex B), the inspection activities shall involve, to a greater or lesser extent, or-ganisations which are independent of the manufacturer.NOTEFor the guidance of the manufacturer, the specific involvement of such organisations, known as responsible authori-ties (RA), is described in CR 12953-14.The manufacturer shall provide all the necessary access to enable the responsible authority to carry out the activitiesin which it is required to be involved.5.2 Approval of personnel5.2.1 Check of welder and welding operator approvalThe manufacturer shall certify that the welding of the boiler has been done by welders and welding operators whohave been approved under the requirements of EN 12953-4:2002, 5.15.3.2 and the appropriate certification shall bemade available on request.5.2.2 Approval of non-destructive examination personnelFor the purposes of this standard the term non-destructive examination (NDE) covers the conventional techniques ofvisual, radiographic, ultrasonic, 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 visual examination of welds and final inspection of boilers, forwhich 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 European Standard, to identify and interpret imperfections that might occur at thesurface of the weld and the heat affected zone.Radiographs shall be viewed by personnel qualified to level 2 of EN 473 as a minimum.Magnetic particle inspection, penetrant inspection and ultrasonic examination shall be performed under the direct su-pervision of personnel qualified to level 2 of EN 473 as a minimum.SIST EN 12953-5:2002
