27 FOREWORD
28 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization
29 comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to p
30 2) romote international co-operation on all questions concerning standardization in the electrical and electronic
31 fields. To this end and in addition to other activities, IEC publishes International Standards, Technical
32 Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred
33 to as "IEC Publication(s)"). Their preparation is entrusted to technical committees; any IEC National
34 Committee interested in the subject dealt with may participate in this preparatory work. International,
35 governmental and non-governmental organizations liaising with the IEC also participate in this preparation.
36 IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with
37 conditions determined by agreement between the two organizations.
38 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
39 consensus of opinion on the relevant subjects since each technical committee has representation from all
40 interested IEC National Committees.
41 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
42 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
43 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
44 misinterpretation by any end user.
45 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
46 transparently to the maximum extent possible in their national and regional publications. Any divergence between
47 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
48 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
49 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
50 services carried out by independent certification bodies.
51 6) All users should ensure that they have the latest edition of this publication.
52 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
53 members of its technical committees and IEC National Committees for any personal injury, property damage or
54 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
55 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
56 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
57 indispensable for the correct application of this publication.
58 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
59 rights. IEC shall not be held responsible for identifying any or all such patent rights.

61 94: All-or-nothing electrical relays.
