35 FOREWORD
36 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
37 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
38 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
39 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
40 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
41 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
42 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
43 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
44 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
45 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
46 consensus of opinion on the relevant subjects since each technical committee has representation from all
47 interested IEC National Committees.
48 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
49 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
50 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
51 misinterpretation by any end user.
52 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
53 transparently to the maximum extent possible in their national and regional publications. Any divergence between
54 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
55 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
56 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
57 services carried out by independent certification bodies.
58 6) All users should ensure that they have the latest edition of this publication.
59 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
60 members of its technical committees and IEC National Committees for any personal injury, property damage or
61 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
62 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
63 Publications.
64 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
65 indispensable for the correct application of this publication.
66 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
67 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
68 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
69 may be required to implement this document. However, implementers are cautioned that this may not represent
70 the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
71 shall not be held responsible for identifying any or all such patent rights.
72 IEC 63522-46 has been prepared by IEC technical committee 94: Electrical relays. It is an
73 International Standard.
74 The text of this International Standard is based on the following documents:
