ELECTROMECHANICAL ELEMENTARY RELAYS –
Part 1: General and safety requirements
FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to
technical committees; any IEC National Committee interested in the subject dealt with may participate in this
preparatory work. International, governmental and non-governmental organizations liaising with the IEC also
participate in this preparation. IEC collaborates closely with the International Organization for Standardization
(ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61810-1 has been prepared by IEC technical committee 94: All-or-
nothing electrical relays.
This second edition cancels and replaces the first edition published in 1998 and IEC 61810-5,
published in 1998. This edition constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
94/182/FDIS 94/186/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A bilingual version of this document may be issued at a later date.
---------------------- Page: 10 ----------------------
61810-1 © IEC:2003(E) – 5 –
This new edition has been completely revised in order to
– establish a stand-alone standard for the type testing of electromechanical elementary
relays,
– incorporate and update the requirements and tests with regard to insulation coordination
as contained in former IEC 61810-5:1998,
– improve the structure of the standard to achieve better readability,
– update various requirements and tests.
The committee has decided that the contents of this publication will remain unchanged until
2005. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

ELECTROMECHANICAL ELEMENTARY RELAYS –
Part 1: General and safety requirements
1 Scope
This part of IEC 61810 applies to electromechanical elementary relays (non-specified time all-
or-nothing relays) for incorporation. It defines the basic safety-related and functional
requirements for applications in all areas of electrical engineering or electronics, such as:
• general industrial equipment,
• electrical facilities,
• electrical machines,
• electrical appliances for household and similar use,
• information technology and business equipment,
• building automation equipment,
• automation equipment,
• electrical installation equipment,
• medical equipment,
• control equipment,
• telecommunications,
• vehicles,
• transportation,
• etc.
Compliance with the requirements of this standard is verified by the type tests indicated.
In case the application of a relay determines additional requirements exceeding those
specified in this standard, the relay should be assessed in line with this application in
accordance with the relevant IEC standard(s) (for example IEC 60730-1, IEC 60335-1,
IEC 60950-1).

3.1.1
marking
identification of a relay which, when completely given to the manufacturer of this relay, allows
the unambiguous indication of its electrical, mechanical, dimensional and functional
parameters
EXAMPLE Through the indication of the trade mark and the type designation on the relay, all relay-specific data
