SIST EN 61810-3:2015

Relays with forcibly guided (mechanically linked) contacts (IEC 61810-3:2015)

This part of IEC 61810 specifies special requirements and tests for elementary relays with
forcibly guided contacts, also known as mechanically linked contacts. These special
requirements apply in addition to the general requirements of IEC 61810-1.
NOTE 1 This standard does not apply to electromechanical control circuit devices as described in IEC 60947-5-1.
NOTE 2 IEC 61810-2-1 provides guidelines for the assignment of reliability values.
NOTE 3 Contacts that are not mechanically linked (forcibly guided) are not considered in this standard.

Relais électromécaniques élémentaires - Partie 3: Relais à contacts guidés (liés mécaniquement) (IEC 61810-3:2015)

L'IEC 61810-3:2015 spécifie les exigences et essais particuliers pour les relais élémentaires à contacts guidés, également connus sous le nom de contacts liés mécaniquement. Ces exigences particulières s'appliquent en plus des exigences générales de l'IEC 61810-1.

Releji s prisilnim vodenjem (mehansko povezanih) kontaktov (IEC 61810-3:2015)

Ta del standarda IEC 61810 določa posebne zahteve in preskuse za osnovne releje s prisilnim vodenjem kontaktov, znanih tudi kot mehansko povezani kontakti. Te posebne zahteve se uporabljajo poleg splošnih zahtev iz standarda IEC 61810-1.
OPOMBA 1: Ta standard se ne uporablja za elektromehanske krmilne naprave iz standarda IEC 60947-5-1.
OPOMBA 2: Standard IEC 61810-2-1 zagotavlja smernice za ocenjevanje vrednosti zanesljivosti.
OPOMBA 3: Kontakti, ki niso mehansko povezani (s prisilnim vodenje), niso obravnavani v tem standardu.

ELECTROMECHANICAL ELEMENTARY RELAYS –

Part 3: Relays with forcibly guided (mechanically linked) contacts

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, Publicly Available Specifications (PAS) 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 itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
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 61810-3 has been prepared by IEC technical committee 94: All-or-
nothing electrical relays.
The content of this standard was already published in EN 50205:2002. The revisions in this
standard only involve editorial changes and update of references.
The text of this standard is based on the following documents:
