Electromechanical elementary relays - Part 2-1: Reliability - Procedure for the verification of B10 values
IEC 61810-2-1:2011 specifies reliability test procedures for electromechanical elementary relays when enhanced requirements for the verification of reliability apply. Particular provisions are given for relays incorporated in safety-related control systems of machinery in accordance with IEC 62061 and ISO 13849-1. For such relays B10 values for dangerous failures (B10d values) are derived from the tests specified in this standard. This International Standard is only intended to be used in conjunction with IEC 61810-2.

Relais électromécaniques élémentaires - Partie 2-1: Fiabilité - Procédure de vérification des valeurs de B10
La CEI 61810-2-1:2011 spécifie les procédures d'essai de fiabilité pour les relais électromécaniques élémentaires lorsque des exigences renforcées pour la vérification de la fiabilité s'appliquent. Des dispositions particulières sont fournies pour les relais incorporés dans les systèmes de contrôle liés à la sécurité des machines selon la CEI 62061 et l'ISO 13849-1. Pour ces relais, les valeurs de B10 pour des défaillances dangereuses (valeurs de B10d) sont dérivées des essais spécifiés dans la présente norme. La présente Norme internationale doit être utilisée uniquement conjointement avec la CEI 61810-2.
Osnovni elektromehanski releji - 2. del: Zanesljivost - Postopki za overjanje vrednosti B10
Ta del IEC 61810 določa postopke za preskušanje zanesljivosti za osnovne elektromehanske releje, kadar veljajo ostrejše zahteve za overjanje zanesljivosti.
Podane so konkretne določbe za releje, vgrajene v varnostne krmilne sisteme strojev v skladu z IEC 62061 in ISO 13849-1. Za take releje se vrednosti B10 za nevarne okvare (vrednosti B10d) izpeljejo iz preskusov, določenih s tem standardom. Ta mednarodni standard je namenjen samo uporabi skupaj z ISO 61810-2.

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 61810-2-1 has been prepared by IEC technical committee 94: All-
or-nothing electrical relays.
This standard cancels and replaces IEC/PAS 61810-2-1 published in 2008. This edition
constitutes a technical revision.
This standard includes the following significant technical changes with respect to
IEC/PAS 61810-2-1:
• addition of inductive loads in Clause 4;
• specification of dielectric tests under Clause 4 and Clause 5;
.
• addition of informative Annex A illustrating the assessment of malfunctions for B
