13、lers”, 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of an identical text or by endorsement, at the latest by April 2013, and conflicting national standards shall be withdrawn at the latest by April 2013. Atten
14、tion 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 rights. This document has been prepared under a mandate given to CEN by the European Commission and
15、 the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive 97/23/EC, see informative Annex ZA, which is an integral part of this document. The European Standard series EN 12952 concerning water-tube boilers and auxiliary installat
16、ions 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 life expectancy calculations; Part 5: Workmanship and construction of pressure parts of the boiler; Par

20、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. As such, the design and manufacture of water-tube boilers requires the application of more than one part i
21、n order for the requirements of the standard to be satisfactorily fulfilled.

24、 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 what extent the following aspects are used for the establishment of an operating instruction depends on the st
25、ipulated 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 pressure equipment and “auxiliary” plant such as motors, pumps and fans. 2 Normative references The following document
