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
36 Reports, 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
38 with may participate in this preparatory work. International, governmental and non -governmental organizations
39 liaising with the IEC also participate in this preparation. IEC collaborates closely with the International
40 Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two
41 organizations.
42 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
43 consensus of opinion on the relevant subjects since each technical committee has representation from all
44 interested IEC National Committees.
45 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
46 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
47 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
48 misinterpretation by any end user.
49 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
50 transparently to the maximum extent possible in their national and regional publications. Any divergence between
51 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
52 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
53 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
54 services carried out by independent certification bodies.
55 6) All users should ensure that they have the latest edition of this publication.
56 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
57 members of its technical committees and IEC National Committees for any personal injury, property damage or
58 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
59 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
60 Publications.
61 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
62 indispensable for the correct application of this publication.
63 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subjec t of patent
64 rights. IEC shall not be held responsible for identifying any or all such patent rights.
65 The International Standards of the IEC 61810 have been prepared by IEC technical committee
66 94: All-or-nothing electrical relays.
67 The text of this International Standard is based on the following documents:
