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.

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
