30、 for making and shaping of metals - Safety requirements”, 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 August 2012, and conflicting national standards s

31、hall be withdrawn at the latest by August 2012. 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 patent rights. This document has been prepared under

32、a mandate 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 document. According to the CEN/CENELEC Internal Regula

BS EN 15949:2012EN 15949:2012 (E) 6 Introduction This document is a type C standard as stated in EN ISO 12100:2010. The equipment concerned and the extent to which hazard

35、s, hazardous situations and events are covered are indicated in the scope of this standard. When provisions of this type C standard are different from those which are stated in type A or B standards, the provisions of this type C standard take precedence over the provisions of the other standards, f

36、or machines that have been designed and built according to the provisions of this type C standard. Where for clarity an example of a preventative measure is given in the text, this should not be considered as the only possible solution. Any other solution leading to the same risk reduction is permis

37、sible if an equivalent level of safety is achieved. This European Standard assumes that the equipment is operated and maintained by trained personnel. BS EN 15949:2012EN 15949:2012 (E) 7 1 Scope This European Standard defines the general safety requirements for hot rolling mills for long products as

38、 defined in 3.1. This European Standard deals with significant hazards, hazardous situations and events relevant to hot rolling mills for long products. It deals not only with circumstances where the machinery is used as intended, but also includes other conditions foreseen by the manufacturer, such

39、 as foreseeable faults, malfunctions or misuse (see Clauses 4 and 5). This applies also to hazards arising during various phases of the life of the machinery and equipment as described in 5.4 of EN ISO 12100:2010. This European standard applies to: Machinery and equipment used for the manufacturing

40、of metal rolled long products from the material supply from (1), via the rolling mill process equipment (2) to (9) including preparation area (10) (exemplary layout is given in Figure 1).
