35、6:2018 IEC 2018 INTERNATIONAL ELECTROTECHNICAL COMMISSION _ SPECIFICATION OF TECHNICAL GRADE SULPHUR HEXAFLUORIDE (SF6) AND COMPLEMENTARY GASES TO BE USED IN ITS MIXTURES FOR USE IN ELECTRICAL EQUIPMENT FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for s

36、tandardization 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 other activities, IEC publishes

37、 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 subject dealt with may parti

38、cipate 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 conditions determined by agreement bet

39、ween 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 Committees. 3) IEC Publicati

40、ons 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 which they are used or for a

41、ny 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 Publication and the correspondin

42、g 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 is not responsible for any ser

43、vices 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 technical committees and IEC Na

44、tional 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 IEC Publications. 8) Attention

45、 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 subject of patent rights. IEC sh

46、all not be held responsible for identifying any or all such patent rights. International Standard IEC 60376 has been prepared by IEC technical committee 10: Fluids for electrotechnical applications. This third edition cancels and replaces the second edition published in 2005. This edition constitute

47、s a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the requirements for the use of SF6in electrical equipment have been confirmed; b) a specification for complementary gases to be used in SF6mixtures with N2and CF4 has b

48、een included; c) the introduction and scope have been merged; d) a new repartition of the annexes of IEC 60376, IEC 60480 and IEC 62271-4 has been included.
