36、ndardization 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 I

37、nternational 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 partici

38、pate 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 betw

39、een 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 Publicatio

40、ns 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 an

41、y 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 corresponding

42、 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 serv

43、ices 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 Nat

44、ional 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 sha

46、ll not be held responsible for identifying any or all such patent rights. International Standard IEC 60984 has been prepared by IEC technical committee 78: Live working. This second edition cancels and replaces the first edition, published in 1990 and its Amendment 1 published in 2002. It constitute

47、s a technical revision. The major changes are: removal of the requirement for an area to mark the date of inspection; only the straight mounting method with water electrodes is specified for the dielectric type test; the d.c. electric tests are no longer included in the normative part of the documen

48、t, but a d.c. test is suggested at the production level where a d.c. use of sleeves is expected, as presented in a new informative Annex E; preparation of the elements of evaluation of defects, and general application of IEC 61318:2007; 6 IEC 60984:2014 IEC 2014 the normative Annex E on sampling pro

49、cedure has been deleted (not applicable according to IEC 61318:2007 ); the informative Annex F on acceptance and complementary tests has been deleted (consideration now included in IEC 61318:2007); in the new normative Annex F, updating of the characteristics of the liquid specified for tests on sleeves of category H, according to the latest edition of ISO 1817; introd
