36、HANICAL ELEMENTARY RELAYS Part 7: Test and measurement procedures 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 internation
37、al 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 Guides (hereafter refe
38、rred 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 also participate i
39、n 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 possible, an interna
40、tional 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. While all reasonab
41、le 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 undertake to apply IEC Pu
42、blications 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 provides no marking procedure to indicate its approv
43、al and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication. 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 exp
44、erts 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 publication, use of, or reliance upon, this IEC
45、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 possibility that some of the elements of this IEC
46、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 61810-7 has been prepared by IEC technical committee 94: All-or- nothing electrical relays. This bilingual version (2014-05) corresponds to the
47、 English version, published in 2006-03. This second edition cancels and replaces the first edition published in 1997. This second edition constitutes a technical revision. This new edition has been revised in order to update all normative references, adapt its contents to the newest issues of the ot
48、her parts of this series of basic relay standards (IEC 61810-1 and IEC 61810-2), establish coherence with other IEC standards (for example of the IEC 60068-2 series), improve test and measurement procedures where appropriate, delete those tests no longer used in case of elementary relays for industr
49、ial application. 6 IEC 61810-7:2006 IEC 2006 The text of this standard is based on the following documents: FDIS Report on voting 94/226/FDIS 94/231/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.
