25、 worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to ot

26、her activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the

27、 subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with condition

28、s determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National

29、 Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in

30、 which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Pub

31、lication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC i

32、s not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its te

33、chnical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other I

34、EC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the sub

35、ject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 60519-4 has been prepared by IEC technical committee 27: Industrial electroheating and electromagnetic processing. This fourth edition cancels and replaces the third edi

36、tion published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: The structure has been amended and adjusted to IEC 60519-1:2010; The classification (Clause 4) has been adapted to details wi

37、th respect to secondary voltage in electric arc furnace installations; All provisions have been redrafted and the text is more concise with respect to EAF; Annexes AA, BB and CC have been restructured, with respect to details concerning high voltage designs and non-electrical issues, however to be a

38、ware of in those installations. 4 60519-4 IEC:2013 The text of this standard is based on the following documents: FDIS Report on voting 27/904/FDIS 27/928/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publ

39、ication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all the parts of IEC 60519 series, under the general title Safety in electroheating installations, can be found on the IEC website. The clauses of parts of the IEC 60519 series (hereinafter called Particular Requir

40、ements) supplement or modify the corresponding clauses of IEC 60519-1:2010 (General requirements hereinafter called Part 1). This part of IEC 60519 is to be read in conjunction with Part 1. It supplements or modifies the corresponding clauses of Part 1. Where the text indicates an “addition“ to or a

41、 “replacement“ of the relevant provision of Part 1, these changes are made to the relevant text of Part 1. Where no change is necessary, the words “This clause of Part 1 is applicable“ are used. When a particular subclause of Part 1 is not mentioned in this part, that subclause applies as far as is

42、reasonable. Additional specific provisions to those in Part 1, given as individual clauses or subclauses, are numbered starting from 101. NOTE The following numbering system is used: subclauses, tables and figures that are numbered starting from 101 are additional to those in Part 1; unless notes ar

43、e in a new subclause or involve notes in Part 1, they are numbered starting from 101, including those in a replaced clause or subclause; additional annexes are lettered AA, BB, etc. The committee has decided that the contents of this publication will remain unchanged until the stability date indicat

44、ed on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 60519-4 IEC:2013 5 SAFETY IN ELECTROHEATING INSTALLATIONS Part 4: Particular requirements for

45、 arc furnace installations 1 Scope and object This clause of Part 1 is replaced by the following. Replacement: This part of IEC 60519 provides particular safety requirements for electric arc furnace installations and its operating and maintenance personnel. These safety provisions concern the protec

46、tion of persons and the environment against dangers of electrical origin and also against certain dangers of non-electrical origin. This standard is applicable to electroheating installations such as: a) Furnaces for direct arc heating, forming arcs between the electrode and metal such as the electr

47、ic arc furnace using alternating current (EAFac) or direct current (EAFdc), and ladle furnace (LF); b) Furnaces for arc-resistance heating forming arcs between the electrode and the charge material or heating the charge material by the Joule effect, such as the submerged arc furnace using alternatin

48、g current (SAFac), or direct current (SAFdc). NOTE For purposes of this document abbreviation EAF is used for all kinds of electric arc furnace installations. 2 Normative references This clause of Part 1 is applicable with the following additions.
