22、NS ENVIRONMENTAL CONDITIONS FOR EQUIPMENT Part 1: Equipment on board rolling stock 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 pr
23、omote 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, Publicly Available Specifications (PAS) and Guide
24、s (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- governmental organizations liaising with the IEC a
25、lso 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 on technical matters express, as nearly as pos
26、sible, 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 accepted by IEC National Committees in that sense. W
27、hile 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 international uniformity, IEC National Committees undertak
28、e 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 latter. 5) IEC itself does not provide any attesta
29、tion 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 should ensure that they have the latest edition of
30、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 damage of any nature whatsoever, whether direct or
31、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 the referenced publications is indispensable fo
32、r 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 rights. International Standard IEC 62498-1 has been
33、prepared by IEC technical committee 9: Electrical equipment and systems for railways. This standard is based on EN 50125-1. The text of this standard is based on the following documents: FDIS Report on voting 9/1402/FDIS 9/1451/RVD Full information on the voting for the approval of this standard can
34、 be found in the report on voting indicated in the above table. A list of all parts of IEC 62498 series, under the general title Railway applications Environmental conditions for equipment, can be found on the IEC website. 4 62498-1 IEC:2010 This publication has been drafted in accordance with the I
35、SO/IEC Directives, Part 2. 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 reconfirmed, wi
36、thdrawn, replaced by a revised edition, or amended. 62498-1 IEC:2010 5 RAILWAY APPLICATIONS ENVIRONMENTAL CONDITIONS FOR EQUIPMENT Part 1: Equipment on board rolling stock 1 Scope This part of IEC 62498 intends to define environmental conditions. The scope of this standard covers the use of on board
37、 electrical, electromechanical and electronic equipment for rolling stock, for the following parameters: altitude, temperature, humidity, air movement, rain, snow and hail, ice, solar radiation, lightning, pollution, vibrations and shocks, electromagnetic interference environment, acoustic noise env
38、ironment, supply system characteristics. In particular the standard defines: interface conditions between the vehicle and its environment; general environmental rules for the equipment of rolling stock, especially for the main sub- systems. In this respect it gives general guidance in order to allow
39、 the fairness of bid assessments. The defined environmental conditions are considered as normal in service; occasionally more severe conditions may be specified. Microclimates surrounding components may be defined by relevant product standards or by special requirements. This standard is not intende
40、d to apply to cranes, mining vehicles, cable cars. Passenger effects on the equipment and equipment effects on the passengers are not considered in this standard. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, o
41、nly the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
