34、g 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 other activities, IEC publishes International Standards
35、, 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 subject dealt with may participate in this preparato
36、ry 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 conditions determined by agreement between the two organizati
37、ons. 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 Committees. 3) IEC Publications have the form of re
38、commendations 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 which they are used or for any misinterpretation by
39、 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 Publication and the corresponding national or regional
40、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 is not responsible for any services carried out by in
41、dependent 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 technical committees and IEC National Committees for a
42、ny 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 IEC Publications. 8) Attention is drawn to the Normat
43、ive 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 subject of patent rights. IEC shall not be held respons
44、ible for identifying any or all such patent rights. International Standard IEC 60974-10 has been prepared by IEC technical committee 26: Electric welding. This third edition cancels and replaces the second edition published in 2007 and constitutes a technical revision. This edition includes the foll
45、owing significant technical changes with respect to the previous edition: inclusion of optional use of a decoupling network and a load outside the test chamber; inclusion of an alternative test setup for portable equipment; inclusion of test conditions for complex controls, liquid cooling systems an
46、d arc striking and stabilizing devices; update of the applicable limits related to the updated reference to CISPR 11; exclusion of the use of narrow band relaxations for RF emission limits; 60974-10 IEC:2014 5 update of the applicable limits for harmonics and flicker and inclusion of flow-charts rel
47、ated to the updated reference to IEC 61000-3-11 and IEC 61000-3-12; update of the requirements for voltage dips related to the updated reference to IEC 61000-4-11 and IEC 61000-4-34; update of the informative annex for installation and use; inclusion of symbols to indicate the RF equipment class and
48、 restrictions for use. The text of this standard is based on the following documents: FDIS Report on voting 26/519/FDIS 26/526/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 publication has been drafted in
49、accordance with the ISO/IEC Directives, Part 2. The list of all the parts of the IEC 60974 series, under the general title Arc welding equipment, can be found on the IEC web site.
