2 INTERNATIONAL ELECTROTECHNICAL COMMISSION

5 Electrical relays – Tests and Measurements –
7 Part 3: Relay coil properties
9 FOREWORD
10 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
11 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
12 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
13 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
14 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
15 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
16 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
17 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
18 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
19 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
20 consensus of opinion on the relevant subjects since each technical committee has representation from all
21 interested IEC National Committees.
22 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
23 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
24 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
25 misinterpretation by any end user.
26 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
27 transparently to the maximum extent possible in their national and regional publications. Any divergence between
28 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
29 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
30 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
31 services carried out by independent certification bodies.
32 6) All users should ensure that they have the latest edition of this publication.
33 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
34 members of its technical committees and IEC National Committees for any personal injury, property damage or
35 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
36 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
37 Publications.
38 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
39 indispensable for the correct application of this publication.
40 9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
41 patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
42 respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
43 may be required to implement this document. However, implementers are cautioned that this may not represent
44 the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
45 shall not be held responsible for identifying any or all such patent rights.
46 IEC 63522-3 has been prepared by IEC technical committee 94: Electrical relays. It is an
47 International Standard.
49 The text of this International Standard is based on the following documents:
CD CC
94/948/CD 94/1020/CC
51 Full information on the voting for the approval of this International Standard can be found in the
52 report on voting indicated in the above table.
53 The language used for the development of this International Standard is English.

54 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
55 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
56 at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
57 described in greater detail at www.iec.ch/publications.
58 A list of all parts of IEC 63522 series, published under the general title Electrical relays – Relay
59 coil properties, can be found on the IEC website.
60 The committee has decided that the contents of this document will remain unchanged until the
61 stability date indicated on the IEC website under webstore.iec.ch in the data related to the
62 specific document. At this date, the document will be
