27、s a worldwide organization for standardization 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
28、 other activities, IEC publishes 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
29、the subject dealt with may participate 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 condit
30、ions determined by agreement between 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 Natio
31、nal Committees. 3) IEC Publications 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
32、 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 apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC
33、Publication and the corresponding 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. IE
34、C 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 publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its
35、 technical committees and IEC National 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 othe
36、r IEC Publications. 8) Attention 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
37、subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62718 has been prepared by IEC technical committee 9: Electrical equipment and systems for railways. This standard is based on EN 50311:2003. The text of this standar
38、d is based on the following documents: FDIS Report on voting 9/1769A/FDIS 9/1798/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 accordance with the ISO/IEC Directives, Part 2
39、. BS EN 62718:201662718 IEC:2013 5 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 publication. At this date, the publication will be reconfi
40、rmed, withdrawn, replaced by a revised edition, or amended. BS EN 62718:2016 6 62718 IEC:2013 INTRODUCTION This International Standard has been developed specifically for railway applications, to supplement the current standards. It covers general safety and performance requirements in addition to o
41、r in place of those contained in IEC 61347-1, IEC 61347-2-3 and 61347-2-7. NOTE 1 When applied unchanged, the clauses of IEC 61347 are either referred in this standard or introduced into it if they are short texts. NOTE 2 When a clause of IEC 61347 applies with changes or is replaced by more specifi
42、c requirements, generally a short note explains the difference or the reason for that. BS EN 62718:201662718 IEC:2013 7 RAILWAY APPLICATIONS ROLLING STOCK DC SUPPLIED ELECTRONIC BALLASTS FOR LIGHTING FLUORESCENT LAMPS 1 Scope This International Standard specifies the performance and constructional r
43、equirements, and associated tests, for d.c. supplied electronic ballasts used to supply fluorescent lamps for lighting on railway rolling stock. Its requirements replace those of IEC 61347 for all railway rolling stock applications and specify and complete those of IEC 61347 for the specific needs o
44、f railway rolling stock applications. This international standard applies to electronic ballasts supplying pre-heated cathode fluorescent lamps without integrated starters, tubular or single capped, according to IEC 60081 and IEC 60901 respectively, having a single and non adjustable luminous flux l
45、evel. It does not apply to electronic ballasts supplying non pre-heated cathode lamps and/or lamps with integrated starters. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
