This European Standard shall be given the status o
23、f a national standard, either by publication of an identical text or by endorsement, at the latest by October 2010, and conflicting national standards shall be withdrawn at the latest by October 2010. This document includes Amendment 1, approved by CEN on 2010-02-28. This document supersedes EN 1468

The start and finish of text introduced or altered by amendment is indicated in the text by tags!“XAttention 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
25、 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 EU Directive(s). For relationship with EU Directive(s), see informative Annexes ZA and ZB, which are integral p
26、arts of this document. This European Standard was elaborated by CEN/TC 322/WG1 comprising experts from the following countries: Austria, Germany, Italy and Sweden. NOTE Initially it was planned to prepare this European Standard as a part of the standard series EN 746 “Industrial thermoprocessing equ
27、ipment“. As a result of the time gap between the elaboration of EN 746-1:1997 and this European Standard the goal could not be achieved because of a diverging technical level in both standards. For the next revision of both standards it is foreseen to reconsider the initial plan. According to the CE
28、N/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Li

BS EN 14681:2006+A1:2010EN 14681:2006+A1:2010 (E) 5 Introduction This European Standard is a type C standard as stated in EN ISO 12100. The machinery concern
30、ed and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this European 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 ove
31、r the 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 oth
32、er solution leading to the same risk reduction is permissible if an equivalent level of safety is achieved. BS EN 14681:2006+A1:2010EN 14681:2006+A1:2010 (E) 6 1 Scope This European Standard specifies the general safety requirements for electric arc furnaces (EAF) to melt steel not containing radioa
33、ctive material. This European Standard deals with all significant hazards, hazardous situations and events pertinent to EAF, when used as intended and under conditions foreseen by the manufacturer, but also includes foreseeable faults and malfunctions in case of misuse. This European Standard specif
34、ies also criteria for the plant and equipment integrated in the production process. 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
35、. This European Standard assumes that installations 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. This European Standard covers the following equipment (se
36、e Annex B): EAF with AC technology (alternating current); EAF with DC technology (direct current); scrap pre-heating technology; associated equipment/devices according Annex B. The following equipment is not covered by this European Standard: induction furnace; resistance-arc furnace; electron beam
37、furnace; plasma furnace; other electrical furnaces used in secondary steelmaking. This European Standard does not specify safety requirements for the following equipment, which can be an integral or complementary part of the equipment covered by the Scope: a) cranes; b) scrap basket; c) transport ca
38、r for scrap basket; d) elephant house (furnace encasing for environmental reasons); e) separate scrap drying equipment.
