28、 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of an identical text or by endorsement, at the latest by April 2009, and conflicting national standards shall be withdrawn at the latest by April 2009. Attention is drawn to the possibility that some of t

29、he 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 the European Free Trade Association, and suppo

This European Standard has been elaborated by CEN/TC 322/WG 3, comprising experts from: Denmark, Germany, Italy, Sweden and the United Kin

31、gdom. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, I

BS EN 15094:2008EN 15094:2008 (E) 7 Introduction This document is a type C standard as stated in EN ISO 12100. The machinery concerned an

33、d the extent to which hazards, 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 provisio

34、ns of the other standards, for 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 s

35、ame risk reduction is permissible if an equivalent level of safety is achieved. This European Standard assumes that the equipment is operated and maintained by trained personnel. BS EN 15094:2008EN 15094:2008 (E) 8 1 Scope This European Standard specifies the safety requirements for cold rolling mil

36、ls for flat products (coiled or as heavy plates) as defined in 3.1. This European Standard deals with significant hazards, hazardous situations and events relevant to cold rolling mills for flat products. It deals not only with circumstances where the machinery is used as intended, but also includes

37、 other conditions foreseen by the manufacturer, such as foreseeable faults, malfunctions or misuse (see clauses 4 and 5). This European standard applies to: Machinery and equipment used for the manufacturing of metal cold rolled flat products from the material entry station (1), through the forming

38、stations (2), to the exit (3) (see Figure 1). Key 1 entry section 2 cold rolling mill 3 exit section 4 roll changing device 5 border of the plant Figure 1 Exemplary layout of a cold flat rolling mill The following equipment is outside the scope of this European Standard: furnaces in accordance with

39、EN 746-1, EN 746-2 and EN 746-3; pickling plants according to EN 15061; strip processing lines according to EN 15061; abrasive blasting plants according to EN 1248; roll shop equipment; hook conveyors according to EN 619; storage equipment (e. g., high-bay warehouses); cranes, fork lifts, trucks and

40、 railway trucks and other vehicles.
