The work

11、of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-government

12、al, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. The procedures used to develop this document and those intended for its further maintenance are described in the

13、ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possib

14、ility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of

15、patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of users and does not constitute an endorsement. For an explanation on the voluntary nature of standards, the meaning of ISO specific terms and expressions related to

16、 conformity assessment, as well as information about ISOs adherence to the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see the following URL: www.iso.org/iso/foreword.html.

17、sociated processing equipment.iv ISO 2017 All rights reserved ISO 13578:2017(E) Introduction This document is a type C standard as stated in ISO 12100. The machinery concerned and the extent to which hazards, hazardous situations and events are covered are indicated in the scope of this document. Wh

18、en 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 type C standa

19、rd. Where, for clarity, an example of a preventive measure is given in this document, 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 document is of relevance, in par

20、ticular, for the following stakeholder groups representing the market players with regard to machinery safety: machine manufacturers (small, medium and large enterprises); health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.). Others can be affected by t

21、he level of machinery safety achieved by these stakeholder groups through the use of this document: machine users/employers (small, medium and large enterprises); machine users/employees (e.g. trade unions, organizations for people with special needs); service providers, e.g. for maintenance (small,

22、 medium and large enterprises); consumers (in case of machinery intended for use by consumers). The above-mentioned stakeholder groups have been given the possibility to participate at the drafting process of this document.

23、 equipment Safety requirements for machinery and equipment for production of steel by electric arc furnaces 1 Scope This document specifies the general safety requirements for electric arc furnaces (EAF) to melt steel not containing radioactive material. NOTE Radioactive material is considered to be

24、 detected in front of the steel plant entrance. This document deals with significant hazards, hazardous situations and events as listed in Table 1 pertinent to EAF, when used as intended and under conditions foreseen by the manufacturer, and also includes foreseeable faults and malfunctions in case

25、of misuse. This document also specifies criteria for the plant and equipment integrated in the production process. This document specifies the requirements to be followed during design to ensure the safety of persons, which are to be met during transport, assembly, commissioning, operation, maintena

26、nce and decommissioning of the equipment. This document assumes that installations are operated and maintained by adequately trained personnel. Manual intervention for setting, adjustment and maintenance is accepted as part of the normal use of the equipment. This document covers the following equip

27、ment (see Annex B, Tables B.1 and B.2, and Annex C, Figures C.1 and C.2): EAF with alternating current (AC) technology; EAF with direct current (DC) technology; scrap preheating technology; associated equipment/devices (e.g. inert gas stirring, carbon and oxygen injection systems). The following equ

28、ipment is not covered by this document: induction furnace; resistance-arc furnace (e.g. submerged arc furnace); electron beam furnace; plasma furnace; other electrical furnaces used in secondary steelmaking, e.g. ladle furnace. This document does not specify safety requirements for the following equ

29、ipment, which can be an integral or complementary part of the equipment covered by the scope: cranes; shell lifting cross beam; scrap basket, steel ladle and slag pot; transport cars for scrap baskets, steel ladles and slag pots; INTERNATIONAL ST ANDARD ISO 13578:2017(E) ISO 2017 All rights reserved
