29、TIONS CURRENT COLLECTION SYSTEMS REQUIREMENTS FOR AND VALIDATION OF MEASUREMENTS OF THE DYNAMIC INTERACTION BETWEEN PANTOGRAPH AND OVERHEAD CONTACT LINE FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotech
30、nical 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, Technical Specifications
31、, 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 preparatory work. International, go
32、vernmental 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 organizations. 2) The formal decisio
33、ns 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 recommendations for internat
34、ional 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 any end user. 4) In order
35、 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 publication shall be clear
36、ly 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 independent certification bo
37、dies. 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 any personal injury, proper
38、ty 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 Normative references cited in th
39、is 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 responsible for identifying any o
40、r all such patent rights. International Standard IEC 62846 has been prepared by IEC technical committee 9: Electrical equipment and systems for railways. This standard has been derived from EN 50317. The text of this standard is based on the following documents: FDIS Report on voting 9/2198/FDIS 9/2
41、205/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. IEC 62846:2016 IEC 2016 5 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. The readers attention is drawn to the fact that A
42、nnex A lists all of the “in-some-country” clauses on differing practices of a permanent nature relating to the subject of this standard. The following differing practices of a less permanent nature exist in the countries indicated below. Subclause 3.20: t totalis the total measuring time (China). Su
43、bclause 9.5: The evaluation of the interaction includes counting the number of arcs longer than a predefined length (China). 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 t
44、he data related to the specific publication. 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 co
45、rrect understanding of its contents. Users should therefore print this document using a colour printer. 6 IEC 62846:2016 IEC 2016 RAILWAY APPLICATIONS CURRENT COLLECTION SYSTEMS REQUIREMENTS FOR AND VALIDATION OF MEASUREMENTS OF THE DYNAMIC INTERACTION BETWEEN PANTOGRAPH AND OVERHEAD CONTACT LINE 1
46、Scope This International Standard specifies the functional requirements for output and accuracy of measurements of the dynamic interaction between pantograph and overhead contact line. 2 Normative references The following documents are referred to in the text in such a way that some or all of their
47、content constitutes requirements of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 62486:2010, Railway applications Current collection systems Technical criteria for th
48、e interaction between pantograph and overhead line (to achieve free access) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply.
