Electromechanical all-or-nothing telecom relays of assessed quality - Part 1: Generic specification and blank detail specification
This part of IEC 61811 applies to electromechanical telecom elementary relays. Relays
according to this standard are provided for the operation in telecommunication applications.
However, as electromechanical elementary relays, they are also suitable for particular
industrial and other applications.
This standard selects from IEC 61810 series and other sources the appropriate methods of test to
be used in detail specifications derived from this specification, and contains basic test
schedules to be used in the preparation of such specifications in accordance with this standard.
Detailed test schedules are contained in the detail specifications.

Relais télécom électromécaniques élémentaires soumis au régime d’assurance qualité - Partie 1: Spécification générique et spécification particulière cadre
L'IEC 61811-1:2015 s'applique aux relais télécom électromécaniques élémentaires. Les relais conformes à la présente norme assurent le fonctionnement des applications de télécommunication. Toutefois, comme les relais électromécaniques élémentaires, ils sont également adaptés aux applications industrielles, entre autres. La présente norme sélectionne dans la série IEC 61810 et dans d'autres sources les méthodes d'essai appropriées utilisées dans les spécifications particulières déduites de la présente spécification. Elle contient les programmes d'essai de base à utiliser dans le cadre de la préparation de ces spécifications conformément à la présente norme.
Les programmes d'essai détaillés sont contenus dans les spécifications particulières. Cette deuxième édition de l'IEC 61811-1 annule et remplace l'IEC 61811-1 publiée en 1999, l'IEC 61811-10 publiée en 2002, l'IEC 61811-11 publiée en 2002, l'IEC 61811-50 publiée en 2002, l'IEC 61811-51 publiée en 2002, l'IEC 61811-52 publiée en 2002, l'IEC 61811-53 publiée en 2002, l'IEC 61811-54 publiée en 2002, l'IEC 61811-55 publiée en 2002, et constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport aux éditions précédentes:
a) mise à disposition d'un document concernant les relais télécom;
b) mise à jour de toutes les références appropriées.
Elektromehanski telekomunikacijski stikalni releji ocenjene kakovosti - 1. del: Rodovna specifikacija in okvirna podrobna specifikacija
Ta del standarda IEC 61811 se uporablja za elektromehanske telekomunikacijske osnovne releje. Releji v skladu s tem standardom se zagotavljajo za delovanje v okviru telekomunikacijskih uporab. Vendar so kot elektromehanski osnovni releji primerni tudi za posebne industrijske in druge uporabe.
Ta standard izbira med skupino standardov IEC 61810 in drugimi viri ustrezne metode preskušanja, ki se uporabljajo za podrobne specifikacije, ki izhajajo iz te specifikacije, ter zajema osnovne urnike preskusov, ki se uporabljajo pri pripravi takih specifikacij v skladu s tem standardom. Podrobni urniki preskusov so zajeti v podrobnih specifikacijah.

Part 1: Generic specification and blank detail specification
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 61811-1 has been prepared by IEC technical committee 94: All-or-
nothing electrical relays.
This second edition of IEC 61811-1 cancels and replaces
• IEC 61811-1 published in 1999,

• IEC 61811-55 published in 2002,
and constitutes a technical revision. This edition includes the following significant technical
changes with respect to the previous editions:
a) to get one document for telecom relays;
b) update all relevant references;
The text of this standard is based on the following documents:
FDIS Report on voting
94/379/FDIS 94/383/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.
A list of all parts in the IEC 61811 series, published under the general title Electromechanical
telecom elementary relays of assessed quality, can be found on the IEC website.
Future standards in this series will carry the new general title as cited above. Titles of existing
standards in this series will be updated at the time of the next edition.
This publication was drafted in accordance with ISO/IEC Directives, Part 2.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

1 Scope
This part of IEC 61811 applies to electromechanical telecom elementary relays. Relays
according to this standard are provided for the operation in telecommunication applications.
However, as electromechanical elementary relays, they are also suitable for particular
industrial and other applications.
This standard selects from IEC 61810 series and other sources the appropriate methods of test to
be used in detail specifications derived from this specification, and contains basic test
schedules to be used in the preparation of such specifications in accordance with this standard.
Detailed test schedules are contained in the detail specifications.
