34、CK 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 promote international co-operation on all questions concerning standardization in
35、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 Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entruste
36、d 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 also participate in this preparation. IEC collaborates closely with the Internatio
37、nal 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 possible, an international consensus of opinion on the relevant subjects since each
38、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. While all reasonable efforts are made to ensure that the technical content of IEC
39、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 undertake to apply IEC Publications transparently to the maximum extent possible in their
40、 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 attestation of conformity. Independent certification bodies provide conformity assessmen
41、t 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 this publication. 7) No liability shall attach to IEC or its directors, employees
42、, 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 indirect, or for costs (including legal fees) and expenses arising out of the pub
43、lication, 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 for the correct application of this publication. 9) Attention is drawn to the possi
44、bility 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 60571 has been prepared by IEC technical committee 9: Electrical equipment and systems for railway
45、s. This third edition cancels and replaces the second edition issued in 1998 and its amendment 1 (2006). It constitutes a technical revision. The main technical changes with regard to the previous edition are as follows: a) In 4.1.2, Table 1 has been modified according to IEC 62498-1. Additional exp
46、lanation about the aim of this table is mentioned as notes. b) In 5.1.1.1, “32 V”, ”36 V”, “64 V” and “87 V” have been added as the nominal voltage of equipment according to IEC 60077-1. c) In 5.3 and 5.5.7.2.1 (Figure 1), the word “interference” has been replaced by “disturbance” that is more appro
47、priate because “disturbance” is the cause of “interference”. d) In 12.2.7, “max” of the test waveform duration D has been replaced by “min” in the table in Figure 2. Specifying “min” can be expected to derive the duration time D longer than 1 s but quite near 1,0 s in almost all actual business case
48、. On the other hand, specifying “max” may cause unnecessarily shorter D than 1,0 s. 60571 IEC:2012 7 e) In 5.1.1.2, “0,7 Un” has been changed to “k Un” and some examples for Nickel-cadmium battery and Lead-acid battery are given as NOTE. f) Subclause 12.2.9, Radio frequency test, has been divided in
49、to 12.2.9.1, Radio frequency immunity test, and 12.2.9.2, Radio frequency-emission test. The text of this standard is originally based on EN 50155. It was submitted to the National Committees for voting under the Fast Track Procedure. The text of this standard is based on the following documents: FDIS Report on voting 9/1711/FDIS 9/1735/RVD Full information on the voting for the approval of this standard can be found in the report on voting ind
