15、or standardization comprisingall national electrotechnical committees (IEC National Committees). The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC

16、publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in t

17、his preparation. The IEC collaborates closely with the InternationalOrganization for Standardization (ISO) in accordance with conditions determined by agreement between thetwo organizations.2) The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, anintern

18、ational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3) The documents produced have the form of recommendations for international use and are published in the formof standards, technical specifications, technic

19、al reports or guides and they are accepted by the NationalCommittees in that sense.4) In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydiverge

20、nce between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6) Att

21、ention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.International Standard IEC 62193 has been prepared by IEC technical committee 78: Livewo

22、rking.The text of this standard is based on the following documents:FDIS Report on voting78/513/FDIS 78/523/RVDFull information on the voting for the approval of this standard can be found in the report onvoting indicated in the above table.This publication has been drafted in accordance with the IS

23、O/IEC Directives, Part 2.The committee has decided that the contents of this publication will remain unchanged until 2010.At this date, the publication will be reconfirmed; withdrawn; replaced by a revised edition, or amended.62193 IEC:2003 7 INTRODUCTIONThis International Standard has been prepared

24、 according to the requirements of IEC 61477where applicable.The quality plan elements of this standard were prepared in accordance with the requirementsof IEC 61318.62193 IEC:2003 9 LIVE WORKING TELESCOPIC STICKS ANDTELESCOPIC MEASURING STICKS1 ScopeThis International Standard covers telescopic stic

25、ks and telescopic measuring sticks to beused for live working on a.c. or d.c. electrical installations at 1 000 V and above for a.c. and1 500 V and above for d.c.The telescopic sticks are designed to accept attachments that meet appropriate live workingstandards and, together with these attachments,

26、 may be used to perform mechanical workon live parts at a distance. Telescopic sticks are also designed to accept diagnostic devicesthat meet appropriate live working standards and are used to make the diagnosticdevices reach parts of an installation to be tested. Telescopic measuring sticks, or tel

27、e-scopic sticks equipped with graduations, are used to measure distances to or betweenlive parts.NOTE Under certain circumstances, the telescopic sticks covered by this standard can be used for installingportable earthing or earthing and short-circuiting equipment if the mechanical stresses during u

28、se are lower thanthe rated values.The tools (telescopic sticks and telescopic measuring sticks) covered by this standard are foruse under dry conditions but could also be used under very humid conditions, usingappropriate working procedures.Telescopic hook sticks are not covered by this standard. Te

29、lescopic bonding sticks and anyother speciality telescopic sticks designed at the request of users are not covered by thisstandard.2 Normative referencesThe following referenced documents are indispensable for the application of this document.For dated references, only the edition cited applies.
