28、L ELECTROTECHNICAL COMMISSION _ RAILWAY APPLICATIONS ROLLING STOCK DC SUPPLIED ELECTRONIC BALLASTS FOR LIGHTING FLUORESCENT LAMPS FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC N
29、ational 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, Technical Reports, Pu
30、blicly 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, governmental and non- gov
31、ernmental 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 decisions or agreements of IEC
32、 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 international use and are accep
33、ted 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 to promote internation
34、al 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 clearly indicated in the lat
35、ter. 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 bodies. 6) All users shou
36、ld 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, property damage or other dama
37、ge 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 this publication. Use of
38、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 or all such patent right
39、s. 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 standard is based on the following documents: FDIS Report on voting 9/1769A/FDIS 9/1798/RVD Full information on
40、 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. 62718 IEC:2013 5 The committee has decided that the contents of this publication will remain unchanged
41、 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 reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 62718 IEC:2013 INTRODUCTION This International Standard ha
42、s been developed specifically for railway applications, to supplement the current standards. It covers general safety and performance requirements in addition to or 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 ei
43、ther 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 specific requirements, generally a short note explains the difference or the reason for that. 62718 IEC:2013 7 RAILWAY APPLICATIONS ROLLING STOC
44、K DC SUPPLIED ELECTRONIC BALLASTS FOR LIGHTING FLUORESCENT LAMPS 1 Scope This International Standard specifies the performance and constructional requirements, and associated tests, for d.c. supplied electronic ballasts used to supply fluorescent lamps for lighting on railway rolling stock. Its requ
45、irements replace those of IEC 61347 for all railway rolling stock applications and specify and complete those of IEC 61347 for the specific needs of railway rolling stock applications. This international standard applies to electronic ballasts supplying pre-heated cathode fluorescent lamps without i
46、ntegrated starters, tubular or single capped, according to IEC 60081 and IEC 60901 respectively, having a single and non adjustable luminous flux level. It does not apply to electronic ballasts supplying non pre-heated cathode lamps and/or lamps with integrated starters. 2 Normative references The f
47、ollowing documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60068-2-
