Code for designation of colours (IEC 60757:2021)

This International Standard specifies letter codes for designation of colours and provides rules for their combination to designate colour combinations. The letter codes are intended to be applied in the technical documentation of industrial installations, equipment and products, and in markings of equipment and products.
This basic safety publication is primarily intended for use by technical committees in the preparation of standards in accordance with the principles laid down in IEC Guide 104 and ISO/IEC Guide 51.
It is not intended for use by manufacturers or certification bodies. One of the responsibilities of a technical committee is, wherever applicable, to make use of basic safety publications in the preparation of its publications. The requirements of this basic safety publication will not apply unless specifically referred to or included in the relevant publications.
This International Standard does not specify any requirements for the encoding of colour properties, nor for their visual representation. Such requirements are under the responsibility of the different technical committees.

Code de désignation de couleurs (IEC 60757:2021)

L'IEC 60757:2021 spécifie les codes littéraux de désignation de couleurs et donne des règles régissant leur combinaison, afin de désigner les combinaisons de couleurs. Les codes littéraux sont destinés à être appliqués dans la documentation technique des installations électriques, des équipements et produits électriques, ainsi que dans les marquages des équipements et produits électriques. La présente publication fondamentale de sécurité portant sur des exigences essentielles de sécurité est avant tout destinée à être utilisée par les comités d’études dans le cadre de l’élaboration de publications de sécurité, conformément aux principes établis dans le Guide IEC 104 et le Guide lSO/lEC 51. Elle n’est pas destinée à être utilisée par les fabricants ou les organismes de certification. L’une des responsabilités d’un comité d’études consiste, le cas échéant, à utiliser les publications fondamentales de sécurité dans le cadre de l’élaboration de ses publications. Les exigences de la présente publication fondamentale de sécurité ne s’appliquent pas tant qu’il n’y a pas été fait spécifiquement référence ou qu’elles n’ont pas été incluses dans les publications concernées. Le présent document ne spécifie pas d’exigences relatives au codage des propriétés des couleurs, ni à leur représentation visuelle. De telles exigences relèvent de la responsabilité des différents comités d’études. L'IEC 60757:2021 annule et remplace la première édition parue en 1983. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) restriction des codes à des codes littéraux; b) suppression des anciennes notes superflues; c) ajout d’un paragraphe sur un élément utilisant différentes couleurs par alternance; d) ajout de l'0 avec des exemples de couleurs et leur codage RVB (rouge, vert, bleu) correspondant.

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

26 FOREWORD

27 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

28 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

29 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

30 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

31 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

32 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

33 may participate in this preparatory work. International, governmental and non-governmental organizations liaising

34 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

35 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

36 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

37 consensus of opinion on the relevant subjects since each technical committee has representation from all

38 interested IEC National Committees.

39 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

40 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

41 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

42 misinterpretation by any end user.

43 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

44 transparently to the maximum extent possible in their national and regional publications. Any divergence between

45 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

46 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

47 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

48 services carried out by independent certification bodies.

49 6) All users should ensure that they have the latest edition of this publication.

50 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

51 members of its technical committees and IEC National Committees for any personal injury, property damage or

52 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

53 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

54 Publications.

55 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

56 indispensable for the correct application of this publication.

57 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

58 rights. IEC shall not be held responsible for identifying any or all such patent rights.
