30、CAL COMMISSION _ LOW VOLTAGE ELECTRICAL INSTALLATIONS Part 6: Verification FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote in

31、ternational 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, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (herea

32、fter 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 preparatory work. International, governmental and non- governmental organizations liaising with the IEC also part

33、icipate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, a

34、n 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 recommendations for international use and are accepted by IEC National Committees in that sense. While all

35、 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 any end user. 4) In order to promote international uniformity, IEC National Committees undertake to app

36、ly 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 publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of

37、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 independent certification bodies. 6) All users should ensure that they have the latest edition of this pub

38、lication. 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 any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect

39、, 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 Normative references cited in this publication. Use of the referenced publications is indispensable for the co

40、rrect 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 responsible for identifying any or all such patent rights. International Standard IEC 60364-6 has been prepared

41、 by the IEC technical committee 64: Electrical installations and protection against electric shock. This second edition cancels and replaces the first edition published in 2006 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the

42、 previous edition: a) Normative references updated to current publications; b) Re-numbered to align with current IEC numbering; c) Initial inspection requirements: 3 items added; d) Testing sequence changed; e) General requirements for periodic reporting more details added; f) New Annex A: Table A.1

43、 Specific resistance values for copper conductors; IEC 60364-6:2016 IEC 2016 5 g) Annex D: Example of a diagram suitable for evaluation of voltage drop. Content removed; h) Annex E: Recommendation for electrical equipment which is being re-used in an electrical installation. Content removed; i) Anne

44、x F: Content replaced with new Annex E Model forms for reporting; j) Annex G: Changed to Annex F Model forms for inspection of electrical installations; k) Annex H: Changed to Annex G Model schedule of circuit details and test results; l) Annex H: Listing of notes concerning some countries; m) Bibli

45、ography Updated: The text of this standard is based on the following documents: FDIS Report on voting 64/2107/FDIS 64/2114/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 acco

46、rdance with the ISO/IEC Directives, Part 2. A list of all parts in the IEC 60364 series, published under the general title Low voltage electrical installations, can be found on the IEC website. The readers attention is drawn to the fact that Annex H lists all of the “in-some-country” clauses on diff

47、ering practices of a less permanent nature relating to the subject of this standard. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publicat

48、ion. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Use

49、rs should therefore print this document using a colour printer. 6 IEC 60364-6:2016 IEC 2016 LOW VOLTAGE ELECTRICAL INSTALLATIONS Part 6: Verification 6.1 Scope This part of IEC 60364 provides requirements for initial and periodic verification of an electrical installation.
