21 FOREWORD
22 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization
23 comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to p
24 2) romote international co-operation on all questions concerning standardization in the electrical and electronic
25 fields. To this end and in addition to other activities, IEC publishes International Standards, Technical
26 Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred
27 to as "IEC Publication(s)"). Their preparation is entrusted to technical committees; any IEC National
28 Committee interested in the subject dealt with may participate in this preparatory work. International,
29 governmental and non-governmental organizations liaising with the IEC also participate in this preparation.
30 IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with
31 conditions determined by agreement between the two organizations.
32 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
33 consensus of opinion on the relevant subjects since each technical committee has representation from all
34 interested IEC National Committees.
35 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
36 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
37 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
38 misinterpretation by any end user.
39 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
40 transparently to the maximum extent possible in their national and regional publications. Any divergence between
41 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
42 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
43 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
44 services carried out by independent certification bodies.
45 6) All users should ensure that they have the latest edition of this publication.
46 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
47 members of its technical committees and IEC National Committees for any personal injury, property damage or
48 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
49 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
50 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
51 indispensable for the correct application of this publication.
52 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
53 rights. IEC shall not be held responsible for identifying any or all such patent rights.
54 The International Standards of the IEC 61810 have been prepared by IEC technical committee
55 94: All-or-nothing electrical relays.
56 The text of this International Standard is based on the following documents:
CD Report on voting
94/835/CD 94/458/RVD
58 Full information on the voting for the approval of this International Standard can be found in the
59 report on voting indicated in the above table.
60 This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
61 A list of all parts of IEC 61810 series, published under the general title Electromechanical
62 elementary relays, can be found on the IEC website.
