66 FOREWORD
67 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
68 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
69 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
70 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
71 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
72 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
73 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
74 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
75 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
76 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
77 consensus of opinion on the relevant subjects since each technical committee has representation from all
78 interested IEC National Committees.
79 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
80 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
81 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
82 misinterpretation by any end user.
83 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
84 transparently to the maximum extent possible in their national and regional publications. Any divergence between
85 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
86 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
87 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
88 services carried out by independent certification bodies.
89 6) All users should ensure that they have the latest edition of this publication.
90 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
91 members of its technical committees and IEC National Committees for any personal injury, property damage or
92 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
93 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
94 Publications.
95 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
96 indispensable for the correct application of this publication.
97 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
98 rights. IEC shall not be held responsible for identifying any or all such patent rights.
99 IEC 61810-7 has been prepared by subcommittee WG3: Maintenance of basic relay standards,
100 of IEC technical committee 94: All-or-nothing electrical relays. It is an International Standard.
101 The text of this International Standard is based on the following documents:
CD CC
94/818/CD 94/911/CC
103 Full information on the voting for its approval can be found in the report on voting indicated in
104 the above table.
105 The language used for the development of this International Standard is English.
106 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
107 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available

IEC CDV 61810-7-7:2023 © IEC:2023 – 5 –
108 at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
109 described in greater detail at http://www.iec.ch/standardsdev/publications.
110 A list of all parts of IEC 61810 series, published under the general title Electromechanical
111 elementary relays, can be found on the IEC website.
112 This International Standard is to be used in conjunction with IEC 61810-1:2015.
113 The committee has decided that the contents of this document will remain unchanged until the
114 stability date indicated on the IEC website under webstore.iec.ch in the data related to the
115 specific document. At this date, the document will be
116 • reconfirmed,
117 • withdrawn,
118 • replaced by a revised edition, or
119 • amended.
