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
15、 April 2013, and conflicting national standards shall be withdrawn at the latest by April 2013. 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 paten

For relationship with EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this
17、document. The European Standard series EN 12952 concerning water-tube boilers and auxiliary installations 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: In-service boiler li
18、fe expectancy calculations; Part 5: Workmanship and construction of pressure parts of the boiler; Part 6: Inspection during construction, documentation and marking of pressure parts of the boiler; Part 7: Requirements for equipment for the boiler; Part 8: Requirements for firing systems for liquid a
19、nd gaseous fuels for the boiler; Part 9: Requirements for firing systems for pulverized solid fuels for the boiler; Part 10: Requirements for safeguards against excessive pressure; Part 11: Requirements for limiting devices of the boiler and accessories; Part 12: Requirements for boiler feedwater an
20、d boiler water quality; Part 13: Requirements for flue gas cleaning systems; Part 14: Requirements for flue gas DENOX-systems liquefied pressurized ammonia and ammonia water solution; Part 15: Acceptance tests; Part 16: Requirements for grate and fluidized-bed firing systems for solid fuels for the
21、boiler; DIN EN 12952-18:2013-01 EN 12952-18:2012 (E) 4 CR 12952 Part 17: Guideline for the involvement of an inspection body independent of the manufacturer; Part 18: Operating instructions. Although these parts can be obtained separately, it should be recognised that the parts are inter-dependent.
22、As such, the design and manufacture of water-tube boilers requires the application of more than one part in order for the requirements of the standard to be satisfactorily fulfilled. NOTE A “Boiler Helpdesk“ has been established in CEN/TC 269 which may be contacted for any questions regarding the ap
23、plication of the European Standards series EN 12952 and EN 12953, see the following website: http:/www.boiler-helpdesk.din.de According to the CEN/CENELEC Internal Regulations, the national standards organisations of the following countries are bound to implement this European Standard: Austria, Bel

DIN EN 12952-18:2013-01 EN 12952-18:2012 (E) 5 1 Scope This part of this European Standard specifies the organisation and content of operating instructions for water-tube boilers and auxiliary installations as defined in EN 12952-1 when placed on the market. To
26、 what extent the following aspects are used for the establishment of an operating instruction depends on the stipulated scope of delivery and of the requirements by contract regarding plant operation and maintenance. NOTE The manufacturers scope of supply may be either pressure equipment, or pressur
27、e equipment and “auxiliary” plant such as motors, pumps and fans. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
