Marking of electrical equipment with ratings related to electrical supply - Safety requirements

IEC 61293:2019 establishes minimum requirements and general rules on marking electric equipment with ratings and other characteristics to enable the proper and safe selection and installation of electric equipment related to any supply of electricity. The object of this document is to: • provide general requirements for the marking of the characteristics related to any supply system, such as voltage, current, frequency and power, without any restrictions; • provide technical committees with uniform methods for the marking of electrical ratings of products. This document is primarily intended for application by technical committees when specifying minimum markings of ratings related to any electrical supply of equipment, sub-assemblies and components, but it is also for application by product manufacturers for marking their products. This horizontal standard is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 108. One of the responsibilities of a technical committee is, wherever applicable, to make use of horizontal standards in the preparation of its publications. The contents of this horizontal standard will not apply unless specifically referred to or included in the relevant publications. IEC 61293:2019 cancels and replaces the first edition published in 1994. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) its status as a basic safety publication has been removed, and it has become a horizontal publication in accordance with IEC Guide 108; b) the scope is extended to include the applicability of this document to product manufacturers; c) the addition of a provision that the visibility of the marking during normal operation should be considered; d) more detailed requirements where equipment has a set or range of rated values for a given characteristic; e) requirements regarding the provision of the markings also in the technical documentation have been added; f) some notes have been converted to normative text; g) normative references and references to other standards have been updated.

Kennzeichnung elektrischer Betriebsmittel mit Bemessungsdaten für die Stromversorgung - Anforderungen für die Sicherheit

Marquage des matériels électriques avec des caractéristiques assignées relatives à l'alimentation électrique - Exigences de sécurité

L'IEC 61293:2019 établit les exigences minimales et les règles générales pour le marquage des matériels électriques avec des caractéristiques assignées et autres caractéristiques, afin de pouvoir choisir et installer, de manière adéquate et sûre, les matériels électriques associés à toute source d'alimentation électrique. L'objet de ce document est de: • fournir les exigences générales concernant le marquage, sans aucune restriction, des caractéristiques relatives à toute alimentation, telle que la tension, le courant, la fréquence et la puissance; • fournir aux comités d'études des méthodes uniformes concernant le marquage des caractéristiques assignées électriques des produits. Ce document est destiné principalement à être appliqué par les comités d'études lors de la spécification des marquages minimaux des caractéristiques assignées relatives à toute alimentation électrique de matériels, sous-ensembles et composants. Il est également destiné à être appliqué par les fabricants de produits pour le marquage de leurs produits. Cette norme horizontale est essentiellement destinée à l'usage des comités d'études dans la préparation des normes, conformément aux principes établis dans le Guide 108 de l'IEC. Une des responsabilités d'un comité d'études est, partout où cela est possible, de se servir des normes horizontales lors de la préparation de ses publications. Le contenu de cette norme horizontale ne s'appliquera pas, à moins qu'il ne soit spécifiquement désigné ou inclus dans les publications concernées. L'IEC 61293:2019 annule et remplace la première édition parue en 1994. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) son statut de publication fondamentale de sécurité a été supprimé; b) le domaine d'application est étendu afin d'inclure également l'applicabilité du présent document aux fabricants de produits; c) l'ajout d'une provision pour prendre en compte la visibilité du marquage en fonctionnement normal; d) des exigences plus détaillées ont été ajoutées lorsqu'un matériel comporte un ensemble ou une plage de valeurs assignées pour une caractéristique donnée; e) des exigences concernant l'intégration des marquages également dans la documentation technique ont été ajoutées; f) certaines notes ont été transformées en texte normatif; g) les références normatives et les références à d'autres normes ont été actualisées.

MARKING OF ELECTRICAL EQUIPMENT WITH RATINGS RELATED
TO ELECTRICAL SUPPLY – 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, 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 61293 has been prepared by IEC technical committee 3:

Information structures and elements, identification and marking principles, documentation and

graphical symbols.

This second edition cancels and replaces the first edition published in 1994. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

a) its status as a basic safety publication has been removed, and it has become a horizontal

publication in accordance with IEC Guide 108;

b) the scope is extended to include the applicability of this document to product

manufacturers;

c) the addition of a provision that the visibility of the marking during normal operation should

be considered;
---------------------- Page: 11 ----------------------
SIST EN IEC 61293:2020
– 4 – IEC 61293:2019 © IEC 2019

d) more detailed requirements where equipment has a set or range of rated values for a

given characteristic;

e) requirements regarding the provision of the markings also in the technical documentation

have been added;
f) some notes have been converted to normative text;
g) normative references and references to other standards have been updated.
The text of this International Standard is based on the following documents:
FDIS Report on voting
3/1404/FDIS 3/1414/RVD

Full information on the voting for the approval of this International Standard can be found in

the report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

It has the status of a horizontal standard in accordance with IEC Guide 108.

The reader's attention is drawn to the fact that Table B.1 of Annex B lists all of the "in-some-

country" clauses on differing practices of a less permanent nature relating to the subject of

this standard.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

1 Scope

This International Standard establishes minimum requirements and general rules on marking

electric equipment with ratings and other characteristics to enable the proper and safe

selection and installation of electric equipment related to any supply of electricity.

The object of this document is to:

• provide general requirements for the marking of the characteristics related to any supply

system, such as voltage, current, frequency and power, without any restrictions;

• provide technical committees with uniform methods for the marking of electrical ratings of

This document is primarily intended for application by technical committees when specifying

minimum markings of ratings related to any electrical supply of equipment, sub-assemblies

and components, but it is also for application by product manufacturers for marking their

products.
NOTE For further markings see ISO/IEC Guide 51.

This horizontal standard is primarily intended for use by technical committees in the

preparation of standards in accordance with the principles laid down in IEC Guide 108.

One of the responsibilities of a technical committee is, wherever applicable, to make use of

horizontal standards in the preparation of its publications. The contents of this horizontal

standard will not ap

MARKING OF ELECTRICAL EQUIPMENT WITH RATINGS RELATED
TO ELECTRICAL SUPPLY – 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, 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 61293 has been prepared by IEC technical committee 3:

Information structures and elements, identification and marking principles, documentation and

graphical symbols.

This second edition cancels and replaces the first edition published in 1994. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

a) its status as a basic safety publication has been removed, and it has become a horizontal

publication in accordance with IEC Guide 108;

b) the scope is extended to include the applicability of this document to product

manufacturers;

c) the addition of a provision that the visibility of the marking during normal operation should

be considered;
---------------------- Page: 11 ----------------------

d) more detailed requirements where equipment has a set or range of rated values for a

given characteristic;

e) requirements regarding the provision of the markings also in the technical documentation

have been added;
f) some notes have been converted to normative text;
g) normative references and references to other standards have been updated.
The text of this International Standard is based on the following documents:
FDIS Report on voting
3/1404/FDIS 3/1414/RVD

Full information on the voting for the approval of this International Standard can be found in

the report on voting indicated in the above table.

This document has been drafted in accordance with the ISO/IEC Directives, Part 2.

It has the status of a horizontal standard in accordance with IEC Guide 108.

The reader's attention is drawn to the fact that Table B.1 of Annex B lists all of the "in-some-

country" clauses on differing practices of a less permanent nature relating to the subject of

this standard.

The committee has decided that the contents of this document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

MARKING OF ELECTRICAL EQUIPMENT WITH RATINGS RELATED
TO ELECTRICAL SUPPLY – SAFETY REQUIREMENTS
1 Scope

This International Standard establishes minimum requirements and general rules on marking

electric equipment with ratings and other characteristics to enable the proper and safe

selection and installation of electric equipment related to any supply of electricity.

The object of this document is to:

• provide general requirements for the marking of the characteristics related to any supply

system, such as voltage, current, frequency and power, without any restrictions;

• provide technical committees with uniform methods for the marking of electrical ratings of

products.

This document is primarily intended for application by technical committees when specifying

minimum markings of ratings related to any electrical supply of equipment, sub-assemblies

and components, but it is also for application by product manufacturers for marking their

products.
NOTE For further markings see ISO/IEC Guide 51.

This horizontal standard is primarily intended for use by technical committees in the

preparation of standards in accordance with the principles laid down in IEC Guide 108.

One of the responsibilities of a technical committee is, wherever applicable, to make use of

horizontal standards in the preparation of its publications. The contents of this horizontal

standard will not apply un
