Electromagnetic compatibility (EMC) -- Part 6-7: Generic standards - Immunity requirements for equipment intended to perform functions in a safety-related system (functional safety) in industrial locations

This part of IEC 61000 is intended to be used by suppliers when making claims for the
immunity of equipment intended for use in safety-related systems against electromagnetic
disturbances.
This standard should also be used by designers, integrators, installers, and assessors of
safety-related systems to assess the claims made by suppliers. It provides guidance to
product committees.
This part of IEC 61000 applies to electrical and electronic equipment intended for use in
safety-related systems and that is
• intended to comply with the requirements of IEC 61508 and/or other sector-specific
functional safety standards, and
• intended to be operated in industrial locations as described in 3.1.15.
NOTE 1 The final safety-related system is designed by a system integrator (or equivalent) that has the
responsibility to assess the adequacy of the equipment for the particular application. This process is described in
Annex D of IEC/TS 61000-1-2:2008.
The object of this standard is to define immunity test requirements for equipment in relation to
continuous and transient, conducted and radiated disturbances, including electrostatic
discharge. These requirements apply only to functions intended for use in functional safety
applications. Test requirements are specified for each port considered.
NOTE 2 The immunity requirements of this standard do not, however, cover extreme cases, which can occur at
any location, but with an extremely low probability of occurrence. In consequence, a designer of a safety-related
system checks whether the requirements of this standard cover the expected electromagnetic phenomena within
the intended application.

Compatibilité électromagnétique (CEM) - Partie 6-7: Normes génériques - Exigences d'immunité pour les équipements visant à exercer des fonctions dans un système lié à la sécurité (sécurité fonctionnelle) dans des sites industriels

L'IEC 61000-6-7:2014 est destinée à être utilisée par les fournisseurs lorsqu'ils font des déclarations concernant l'immunité d'équipements destinés à être utilisés dans des systèmes relatifs à la sécurité, contre les perturbations électromagnétiques. Il convient également que cette norme soit utilisée par les concepteurs, les intégrateurs, les installateurs et les vérificateurs des systèmes relatifs à la sécurité afin de vérifier les déclarations faites par les fournisseurs. Elle fournit des lignes directrices aux comités de produits. Cette partie de l'IEC 61000 s'applique aux équipements électriques et électroniques destinés à être utilisés dans les systèmes relatifs à la sécurité et qui sont:
- destinés à être conformes aux exigences de l'IEC 61508 et/ou à d'autres normes de sécurité fonctionnelle spécifiques à un secteur;
- et destinés à être exploités dans des sites industriels, comme cela est décrit en 3.1.15. L'objet de la présente norme est de   définir les exigences d'essai d'immunité des équipements, en ce qui  concerne les perturbations continues et transitoires, conduites  et rayonnées, y compris les décharges électrostatiques. Ces exigences ne s'appliquent qu'aux fonctions destinées à être utilisées  dans des applications de sécurité fonctionnelle. Les exigences d'essai sont spécifiées pour chaque accès considéré.

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 6-7: Generic standards – Immunity requirements
for equipment intended to perform functions in a safety-related
system (functional safety) in industrial locations

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 61000-6-7 has been prepared by TC 77: Electromagnetic
compatibility.
The text of this standard is based on the following documents:

ELECTROMAGNETIC COMPATIBILITY (EMC) –

Part 6-7: Generic standards – Immunity requirements
for equipment intended to perform functions in a safety-related
system (functional safety) in industrial locations



1 Scope and object
This part of IEC 61000 is intended to be used by suppliers when making claims for the
immunity of equipment intended for use in safety-related systems against electromagnetic
disturbances.
This standard should also be used by designers, integrators, installers, and assessors of
safety-related systems to assess the claims made by suppliers. It provides guidance to
product committees.
This part of IEC 61000 applies to electrical and electronic equipment intended for use in
safety-related systems and that is
• intended to comply with the requirements of IEC 61508 and/or other sector-specific
functional safety standards, and
• intended to be operated in industrial locations as described in 3.1.15.
NOTE 1 The final safety-related system is designed by a system integrator (or equivalent) that has the
responsibility to assess the adequacy of the equipment for the particular application. This process is described in
Annex D of IEC/TS 61000-1-2:2008.
The object of this standard is to define immunity test requirements for equipment in relation to
continuous and transient, conducted and radiated disturbances, including electrostatic
discharge. These requirements apply only to functions intended for use in functional safety
applications. Test requirements are specified for each port considered.
NOTE 2 The immunity requirements of this standard do not, however, cover extreme cases, which can occur at
any location, but with an extremely low probability of occurrence. In consequence, a designer of a safety-related
system checks whether the requirements of this standard cover the expected electromagnetic phenomena within
the intended application.
