3、eDocument comprises 54 pagesDIN EN 14677:2008-11 2 Start of validity This standard takes effect on 1 November 2008. 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” (Secretaria
4、t: DIN, Germany). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Technical Committee NA 060-02-01 Stahlerzeugung of Section Htten- und Walzwerksmaschinen. This standard concretizes the basic requirements set
5、out in Annex I of the EU Machinery Directive 98/37/EC (valid until 28 December 2009) and the new EU Machinery Directive 2006/42/EC which becomes applicable on 29 December 2009 relating to machinery and equipment for treatment of liquid steel to be placed on the EEA market, with the intent of simplif
6、ying the means of proving conformity with such requirements. Once this standard is designated a harmonized standard in the Official Journal of the European Union, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (the so-called “presumption
7、of conformity”). The European Standards referred to in clause 2 of this standard have been published as the corresponding DIN EN or DIN EN ISO Standards with the same number. For the International Standard referred to in this standard there is no national standard available. This standard makes refe
8、rence to documents which were valid as of the publication of the European standard. Since then, the standards EN 294 and EN 811 have been withdrawn. Instead, it is recommended to make reference to DIN EN ISO 13857 Safety of machinery Safety distances to prevent hazard zones being In addition, the st

10、eir use is recommended. The standard prEN 15004-1 has been published as EN 15004-1. The reference version contains an error that is corrected here: In subclause 5.4.4 the incorrect reference in the last sentence “For recommendations to the user see 7.2.2, fifth indent.” has been replaced by “For rec

DIN EN 14677:2008-11 EN 14677:2008 (E) 5 Introduction This European Standard is a type C standard as stated in EN ISO 12100. The machines and equipment concerned
35、and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European Standard. When provision 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 th
36、e provisions 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 preventive measure is given in this European Standard, this should not been considered as the only possible solution. Any other s
37、olution leading to the same risk reduction is permissible if an equivalent level of safety is achieved. 1 Scope This European Standard specifies the general safety requirements for secondary steelmaking machinery and equipment (SSE) as defined in 3.1 to treat liquid steel. This European Standard cov
38、ers machinery and equipment involved in the treatment process of liquid steel under vacuum or atmospheric pressure. This European Standard deals with all significant hazards, hazardous situations and events pertinent to SSE, when used as intended and under conditions foreseen by the manufacturer, bu
39、t also includes foreseeable faults and malfunctions in case of misuse. This European Standard specifies the requirements to ensure the safety of persons which are to be met during the design, assembly, transport, commissioning, operation, maintenance and decommissioning of the equipment. This Europe
40、an Standard assumes that SSE are operated and maintained by adequately trained and competent personnel. Manual intervention for setting, adjustment and maintenance is accepted as part of the normal use of the equipment. NOTE 1 Annex B shows examples of SSE. The following equipment is not covered by
41、the scope of this European Standard: cranes; fork lift trucks or other transporting equipment; ladles; equipment for relining and preheating in the relining area; burners according to EN 746-2; dust and fume exhaust systems. NOTE 2 Significant hazards and hazardous situations due to transporting/pos
42、itioning of heavy components, e. g., by cranes (e. g., ladles, vessels, covers) are considered in this standard (see 5.2.3). This European Standard is not applicable to SSE manufactured before the date of publication of this standard in the Official Journal. DIN EN 14677:2008-11EN 14677:2008 (E) 6 2
