31 FOREWORD
32 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
33 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
34 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
35 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
36 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
37 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
38 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
39 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
40 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
41 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
42 consensus of opinion on the relevant subjects since each technical committee has representation from all
43 interested IEC National Committees.
44 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
45 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
46 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
47 misinterpretation by any end user.
48 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
49 transparently to the maximum extent possible in their national and regional publications. Any divergence between
50 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
51 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
52 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
53 services carried out by independent certification bodies.
54 6) All users should ensure that they have the latest edition of this publication.
55 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
56 members of its technical committees and IEC National Committees for any personal injury, property damage or
57 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
58 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
59 Publications.
60 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
61 indispensable for the correct application of this publication.
62 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
63 rights. IEC shall not be held responsible for identifying any or all such patent rights.
64 IEC 61810-7 has been prepared by subcommittee WG3: Maintenance of basic relay standards,
65 of IEC technical committee 94: All-or-nothing electrical relays. It is an International Standard.
66 The text of this International Standard is based on the following documents:
CD CC
94/815/CD 94/915/CC
68 Full information on the voting for its approval can be found in the report on voting indicated in
69 the above table.
70 The language used for the development of this International Standard is English.
71 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
72 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
