27、WAY APPLICATIONS ENVIRONMENTAL CONDITIONS FOR EQUIPMENT Part 3: Equipment for signalling and telecommunications FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees

28、). 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, Publicly Available S

29、pecifications (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- governmental organiza

30、tions 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 on technical matt

31、ers 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 accepted by IEC Nationa

32、l 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 international uniformity, IEC

33、 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 latter. 5) IEC itself

34、 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 should ensure that the

35、y 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 damage of any nature w

36、hatsoever, 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 the referenced pub

37、lications 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 rights. International S

38、tandard IEC 62498-3 has been prepared by IEC technical committee 9: Electrical equipment and systems for railways. This standard is based on EN 50125-3. The text of this standard is based on the following documents: FDIS Report on voting 9/1404/FDIS 9/1453/RVD Full information on the voting for the

39、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. 62498-3 IEC:2010 5 A list of all parts of IEC 62498 series, under the general title Railway applications Environmental con

40、ditions for equipment, can be found on the IEC website. 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 public

41、ation will be reconfirmed, withdrawn, replaced by a revised edition, or amended. 6 62498-3 IEC:2010 RAILWAY APPLICATIONS ENVIRONMENTAL CONDITIONS FOR EQUIPMENT Part 3: Equipment for signalling and telecommunications 1 Scope This part of IEC 62498 specifies the environmental conditions. The scope of

42、this International Standard covers the design and the use of equipment and any portable equipment for signalling and telecommunications systems (including test, measure, monitoring equipment, etc.). The portable equipment must comply with the sections of this International Standard relevant to their

43、 use. This International Standard does not specify the test requirements for equipment. In particular the standard intends to define interface conditions between the equipment and its environment, parameters to be used by designers when calculating RAMS (Reliability, Availability, Maintenability, Sa

44、fety) and life time with respect to environmental condition effects. The defined environmental conditions are considered as normal in service. Microclimates surrounding components may need special requirements to be defined by the product standard. The effects of any signalling and telecommunication

45、s equipment (in either operating or failure mode of operation) on the overall signalling system safety are not within the scope of this International Standard. This International Standard does not provide the designer with information to enable him to determine the safety risk associated with enviro

46、nmental conditions. The safety of persons in the vicinity of (or working on) the signalling and telecommunications equipment is also outside the scope of this International Standard. The effects of vandalism on the equipment are not considered in this International Standard. This International Stand

47、ard applies to all signalling and telecommunications systems except those used for cranes, mining vehicles and cable cars. It does not define the specifications for train-borne signalling and telecommunications systems (see IEC 62498-1). 2 Normative references The following referenced documents are

48、indispensable for the application 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 60529:1989, Degrees of protection provided by enclosures (IP code) IEC 60721-2-1:198
