3、 of validity This standard takes effect on 1 April 2009. National foreword This standard includes safety requirements. This standard has been prepared by Technical Committee CEN/TC 322 “Equipment for making and shaping of metals” (Secretariat: DIN, Germany). The responsible German body involved in i

4、ts preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Section Htten- und Walzwerkseinrichtungen. Representatives of manufacturers and users of cold flat rolling mills, and of the employers liability insurance associations contributed to this standard. This

5、 standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Directive”, Directive 98/37/EC (valid until 28 December 2009), and the “revised Machinery Directive”, Directive 2006/42/EC, which takes effect on 29 December 2009, and which apply to machines th

6、at are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of the directives. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standard and thus,

7、 a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The European Standards referred to in clause 2 and in the bibliography of the EN have been published as the corresponding DIN EN or DIN EN ISO Standards with t

8、he same number. For the International Standards and documents referred to in this standard there are no national standards available unless they have been published as DIN ISO standards with the same number.

This European Standard shall be given the status of a national standard, either by publication of an identical tex

33、t or by endorsement, at the latest by April 2009, and conflicting national standards shall be withdrawn at the latest by April 2009.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 the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible

34、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 supports essential requirements of EC Directive(s). For relationship with EC Directive(s), see informative Annex ZA and

35、B, which is an integral part of this document. This European Standard has been elaborated by CEN/TC 322/WG 3, comprising experts from: Denmark, Germany, Italy, Sweden and the United Kingdom. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following coun

36、tries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spa

The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this

38、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, for machines that have been designed and built according to the provisions of this

39、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 permissible if an equivalent level of safety is achieved. This European Standard assumes

40、 that the equipment is operated and maintained by trained personnel. DIN EN 15094:2009-04 EN 15094:2008 (E) 8 1 Scope This European Standard specifies the safety requirements for cold rolling mills for flat products (coiled or as heavy plates) as defined in 3.1. This European Standard deals with sig

41、nificant 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 other conditions foreseen by the manufacturer, such as foreseeable faults, malfunctions or misuse (see c

42、lauses 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 stations (2), to the exit (3) (see Figure 1).
