Overview

ISO 3767-2:2016 standardizes graphical symbols for operator controls and other displays specifically for agricultural tractors and machinery. Part of the ISO 3767 series, this edition is an extensive technical revision that adds many new symbols. It defines how symbols should be presented, reproduced, grouped and adapted for electronic displays so symbols communicate clearly and consistently across international markets.

Key topics and requirements

• Scope and purpose: Symbols apply to agricultural tractors and machinery as classified in ISO 3339-0 and complement the common symbols in ISO 3767-1.
• Symbol usage rules: Symbols shall be used as shown in the standard; selected outline symbols may be filled for clarity. Minor graphical modifications (line width, rounded corners) are allowed as long as the symbol’s essential meaning remains unchanged.
• Orientation and scaling: Symbols must appear in the prescribed orientation unless specific rotation/mirroring is allowed. Sizing guidance references IEC 80416-1 to ensure legibility and correct visual relationships when symbols are grouped.
• Colour coding for illuminated displays:
  • Red - failure, serious malfunction, immediate attention required
  • Yellow/amber - condition outside normal limits
  • Green - normal operating condition
• Reproduction requirements: Symbols cast, moulded, embossed or stamped must be visually distinct without reliance on colour.
• Location and relation to controls: Symbols shall be placed on or adjacent to the control/display they identify and arranged so control movement toward a symbol corresponds to the function depicted.
• Digital adaptation: Symbols may be adapted into icons for GUIs and reconfigurable displays following ISO 80416-4, preserving the original symbol’s visual impression.
• Development of new symbols: New symbol proposals must follow ISO 3767-1 Annex A and consult ISO 7000/IEC 60417 databases to avoid duplication; proposed symbols require a short explanation of intended use.
• Registration references: Where applicable, ISO/IEC registration numbers (ISO 7000, IEC 60417) are shown for registered symbols.

Applications and users

ISO 3767-2 is essential for:

• Tractor and agricultural machinery manufacturers (control panels, dashboards)
• Human factors, UI/UX and product designers (physical and digital displays)
• Safety and compliance engineers implementing international marking requirements
• Service and training organizations ensuring consistent operator communication
• Regulators and standards bodies harmonizing machine labeling

Practical uses include control panel design, in-cab display iconography, operator manuals, safety labeling, and global product certification.

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
symbol (graphical symbol)
a visually perceptible figure used to transmit information independent of language. It may be produced
by drawing, printing, or other means. Letters, numerals, and mathematical symbols may be used as
symbols or symbol elements. For some specific applications, groups of letters (for example, AUTO,
STOP) are used as symbols or symbol elements.
NOTE Letters and numerals are not registered by ISO/TC 145/SC 3 or published in ISO 7000 unless they are
symbol elements embedded in graphical symbols.
3.2
icon (digital display icon)
a digitized (pixelated) representation of a graphical symbol, usually used on a reconfigurable electronic
display screen or graphical user interface (GUI). A single symbol can be represented by multiple icons,
each of a different size, pixel count, or colourization.
4 General
4.1 Except as indicated in subsequent clauses, symbols shall be used as shown in ISO 3767-2.
4.2 Selected symbols, which are shown in outline form in ISO 3767-2, may be filled in actual use for
enhanced clarity of reproduction and improved visual perception by the operator, except as otherwise
specified for individual symbols. Refer to IEC 80416-3 for guidance.
4.3 Limitations inherent in some reproduction and display technologies can require increased line
width or other minor modifications of symbols. Such modifications are allowed, provided that the
symbol remains conceptually unchanged in its basic graphical elements and is easily discernible by the
operator.
4.4 To improve the appearance and perceptibility of a graphical symbol, or to coordinate with the
design of the equipment to which it is applied, it can be necessary to modify the symbol as indicated in
IEC 80416-3 (for example, to change the line width or to round the corners of the symbol). Such
modifications are allowed, provided that the essential perceptible characteristics of the symbol are
maintained.
4.5 For actual use, all symbols shall be reproduced large enough to be easily discernible by the
operator. See IEC 80416-1 for guidelines on the proper sizing of symbols. Symbols grouped together in
a display or on a set of controls should be scaled to the same degree relative to the corner marks of the
symbol original as shown in ISO 3767-2 in order to maintain the correct visual relationship among the
symbols. Symbols shall be used in the orientation shown in ISO 3767-2, unless rotation or mirror
imaging is specifically allowed for individual symbols.
4.6 Most symbols are constructed using a building block approach in which various symbols and
symbol elements are combined in a logical manner to produce a new symbol.
4.7 In some cases, symbols may be used in conjunction, without being combined into a composite
symbol, to convey the same meaning as the composite symbol.

ISO/DIS 3767-2:2015
4.8 Symbols are generally intended to replace a word or words with a graphical image that has the
same meaning for all operators, regardless of their native language. However, the use of a graphical
symbol to identify a control or display does not preclude the use of words in conjunction with that
control or display.
4.9 If a symbol shows a machine or parts of a machine from a side view, a machine moving from
right to left across the symbol area shall be assumed. If a symbol shows a machine or parts of a machine
from an overhead view, a machine moving from bottom to top across the symbol area shall be assumed.
4.10 Symbols on controls and displays shall have a good contrast to their background. A white or
light-coloured symbol on a black or dark-coloured background is preferred for most controls. Displays
may use either a white or light-coloured symbol on a black or dark-coloured background or a black or
dark-coloured symbol on a white or light-coloured background, depending upon which alternative
provides the best visual perception. When a symbol image is reversed (for example, from black-on-
white to white-on-black or vice versa) this reversal shall be done for the entire symbol.
4.11 If symbols are cast, moulded, embossed, or stamped into a surface, the symbols shall be visually
distinct from that surface without dependence on colour.
4.12 Symbols shall be located on or adjacent to the control or display that is being identified. Where
more than one symbol is required for a control, the symbols shall be located in relation to the control
such that movement of the control towards the symbols shall effect the function depicted by that
symbol.
4.13 Arrows used in symbols shall conform to the requirements of ISO 80416-2. IEC 80416-1 shall be
consulted for the general principles for creating symbol originals. IEC 80416-3 should be consulted for

guidelines for the application of symbols.
4.14 ISO/IEC registration numbers are shown for symbols which are registered in ISO 7000 or
IEC 60417.
NOTE Symbol originals are approved and registered either by ISO/TC 145/SC 3 and published in ISO 7000 or
by IEC/SC 3C and published in IEC 60417. In some cases, modified or application symbols, rather than the
registered symbol originals, are standardized in ISO 3767-2.
4.15 When letters or numerals are used in a symbol, the font shown shall not be considered
definitive. Other fonts may be used so long as the letters and numerals remain legible.
4.16 Symbols in ISO 3767-2 are shown within marks that delimit the corners of the 75 mm square
basic pattern from IEC 80416-1. Corner marks are not part of the symbol, but are provided to ensure
consistent presentation of all symbol graphics.
5 Colour
When used on illuminated displays, the following colours shall have the meanings indicated:
— Red denotes a failure, serious malfunction, or operating condition that requires immediate
attention;
— Yellow or amber denotes a condition outside normal operating limits;
— Green denotes a normal operating condition.
ISO/DIS 3767-2:2015
6 Development of new symbols
6.1 Prior to developing a new symbol, a search should be conducted for previously standardized
symbols with the same or similar meaning to what is needed. ISO 7000 and IEC 60417 (both available in
database form) are compilations of internationally standardized symbols which can be useful both for
finding appropriate symbols that do not appear in one of the parts of ISO 3767 and for generating
concepts that can be used in the development of new symbols.
6.2 New symbols shall be developed in accordance with the principles of ISO 3767-1, Annex A.
IEC 80416-1 should be consulted for general principles for the creation of symbols. Arrows shall be in
accordance with ISO 80416-2. Different arrow forms have different meanings according to ISO 80416-2.
Care should be taken to use the correct arrow form. Following the guidelines of ISO 3767-1, Annex A
makes possible the development of symbols appropriate in graphical form and content for international
standardization and ISO 7000 registration.
6.3 Symbols proposed for standardization in ISO 3767-2 shall include a short explanation of the
function or expected use of the symbol.
NOTE IEC 80416-1 uses the term "description" for this type of information and provides guidelines for
writing descriptions for symbols intended for standardization in ISO 7000 or IEC 60417. The descriptions for
symbols standardized in ISO 3767-2 can serve as examples.
7 Adaptation of symbols as digital display icons
Symbols can be adapted for use as digital display icons on visual display units, reconfigurable displays,
or other electronic displays. Such adaptations should follow the principles of ISO 80416-4. Special care
should be taken to ensure that digital display icons preserve the visual impression of the symbol from
which the icon is adapted. The same principles regarding use of colour with symbols apply to the use of
colour with digital display icons.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 23, Tractors and machinery for agriculture and
forestry, SC 14, Operator controls, operator symbols and other displays, operator manuals.
This fourth edition cancels and replaces the third edition (ISO 3767-2:2008), which has been technically
revised. Many new symbols have been added.

Part 2:
Symbols for agricultural tractors and machinery
1 Scope
This document standardizes symbols for use on operator controls and other displays on agricultural
tractors and machinery.
NOTE 1 ISO 3767-1 covers common symbols that apply to multiple types of agricultural tractors and machinery,
forestry machinery, and powered lawn and garden equipment. ISO 3767-3 covers symbols for powered lawn and
garden equipment. ISO 3767-4 covers symbols for forestry machinery. ISO 3767-5 covers symbols for manual
portable forestry machines.
NOTE 2 ISO 7000 and IEC 60417 can be consulted for additional internationally standardized symbols of
potential relevance to agricultural tractors and machinery.

3.1
symbol
graphical symbol
visually perceptible figure used to transmit information independent of language
Note 1 to entry: It may be produced by drawing, printing or other means. Letters, numerals and mathematical
symbols may be used as symbols or symbol elements. For some specific applications, groups of letters (for
example, AUTO, STOP) are used as symbols or symbol elements.
Note 2 to entry: Letters and numerals are not registered by ISO/TC 145/SC 3 or published in ISO 7000 unless they
are symbol elements embedded in graphical symbols.
3.2
icon
digital display icon
digitized (pixelated) representation of a graphical symbol, usually used on a reconfigurable electronic
display screen or graphical user interface (GUI)
Note 1 to entry: A single symbol can be represented by multiple icons, each of a different size, pixel count or
colourization.
4 General
4.1 Except where indicated in subsequent clauses, symbols shall be used as shown in this document.
4.2 Selected symbols, which are shown in outline form in this document, may be filled in actual use for
enhanced clarity of reproduction and improved visual perception by the operator, except as otherwise
specified for individual symbols, and in accordance with IEC 80416-3.
4.3 Limitations inherent in some reproduction and display technologies can require increased line
width or other minor modifications of symbols. Such modifications are allowed, provided that the symbol
remains conceptually unchanged in its basic graphical elements and is easily discernible by the operator.
4.4 To improve the appearance and perceptibility of a graphical symbol, or to coordinate with the
design of the equipment to which it is applied, it can be necessary to modify the symbol as indicated
in IEC 80416-3 (for example, to change the line width or to round the corners of the symbol). Such
modifications are allowed, provided that the essential perceptible characteristics of the symbol are
maintained.
4.5 For actual use, all symbols shall be reproduced large enough to be easily discernible by the operator.
Follow IEC 80416-1 for the proper sizing of symbols. Symbols grouped together in a display or on a set
of controls should be scaled to the same degree relative to the corner marks of the symbol original as
shown in this document in order to maintain the correct visual relationship among the symbols. Symbols
shall be used in the orientation shown in this document, unless rotation or mirror imaging is specifically
allowed for individual symbols.
4.6 Most symbols are constructed using a building block approach in which various symbols and
symbol elements are combined in a logical manner to produce a new symbol.
4.7 In some cases, symbols may be used in conjunction, without being combined into a composite
symbol, to convey the same meaning as the composite symbol.
4.8 Symbols are generally intended to replace a word or words with a graphical image that has the
same meaning for all operators, regardless of their native language. However, the use of a graphical
symbol to identify a control or display does not preclude the use of words in conjunction with that
control or display.
2 © ISO 2016 – All rights reserved

4.9 If a symbol shows a machine or parts of a machine from a side view, a machine moving from right
to left across the symbol area shall be assumed. If a symbol shows a machine or parts of a machine from
an overhead view, a machine moving from bottom to top across the symbol area shall be assumed.
4.10 Symbols on controls and displays shall have a good contrast to their background. A white or light-
coloured symbol on a black or dark-coloured background is preferred for most controls. Displays may
use either a white or light-coloured symbol on a black or dark-coloured background or a black or dark-
coloured symbol on a white or light-coloured background, depending upon which alternative provides
the best visual perception. When a symbol image is reversed (for example, from black-on-white to white-
on-black or vice versa) this reversal shall be done for the entire symbol.
4.11 If symbols are cast, moulded, embossed or stamped into a surface, the symbols shall be visually
distinct from that surface without dependence on colour.
4.12 Symbols shall be located on or adjacent to the control or display that is being identified. Where
more than one symbol is required for a control, the symbols shall be located in relation to the control
such that movement of the control towards the symbols shall effect the function depicted by that symbol.
4.13 Arrows used in symbols shall conform to the requirements of ISO 80416-2. IEC 80416-1 shall be
consulted for the general principles for creating symbol originals. IEC 80416-3 should be consulted for
guidelines for the application of symbols.
4.14 ISO/IEC registration numbers are shown for symbols which are registered in ISO 7000 or
IEC 60417.
NOTE Symbol originals are approved and registered either by ISO/TC 145/SC 3 and published in ISO 7000
or by IEC/SC 3C and published in IEC 60417. In some cases, modified or application symbols, rather than the
registered symbol originals, are standardized in this document.
4.15 When letters or numerals are used in a symbol, the font shown shall not be considered definitive.
Other fonts may be used so long as the letters and numerals remain legible.
4.16 Symbols in this document are shown within marks that delimit the corners of the 75 mm square
basic pattern from IEC 80416-1. Corner marks are not part of the symbol, but are provided to ensure
consistent presentation of all symbol graphics.
5 Colour
When used on illuminated displays, the following colours shall have the meanings indicated:
— red denotes a failure, serious malfunction or operating condition that requires immediate attention;
— yellow or amber denotes a condition outside normal operating limits;
— green denotes a normal operating condition.
6 Development of new symbols
6.1 Prior to developing a new symbol, a search should be conducted for previously standardized
symbols with the same or similar meaning to what is needed. ISO 7000 and IEC 60417 (both available
in database form) are compilations of internationally standardized symbols which can be useful both for
finding appropriate symbols that do not appear in ISO 3767 and for generating concepts that can be used
in the development of new symbols.
6.2 New symbols shall be developed in accordance with the principles of ISO 3767-1:2016, Annex A.
IEC 80416-1 should be consulted for general principles for the creation of symbols. Arrows shall be in
accordance with ISO 80416-2. Different arrow forms have different meanings according to ISO 80416-
2. Care should be taken to use the correct arrow form. Following the guidelines of ISO 3767-1:2016,
Annex A makes possible the development of symbols appropriate in graphical form and content for
international standardization and ISO 7000 registration.
6.3 Symbols proposed for standardization in this document shall include a short explanation of the
function or expected use of the symbol.
NOTE IEC 80416-1 uses the term “description” for this type of information and provides guidelines for
writing descriptions for symbols intended for standardization in ISO 7000 or IEC 60417. The descriptions for
symbols standardized in this document can serve as examples.
7 Adaptation of symbols as digital display icons
Symbols can be adapted for use as digital display icons on visual display units, reconfigurable displays
or other electronic displays. Such adaptations should follow the principles of ISO 80416-4. Special care
should be taken to ensure that digital display icons preserve the visual impression of the symbol from
which the icon is adapted. The same principles regarding use of colour with symbols apply to the use of
colour with digital display icons.

3.1
symbole
symbole graphique
figure visuellement perceptible utilisée pour transmettre des informations compréhensibles
indépendamment de la langue
Note 1 à l’article: Il peut être reproduit par un dessin, une impression ou tout autre moyen. Les lettres, les
caractères numériques et les symboles mathématiques peuvent être employés comme symboles ou éléments
de symbole. Pour certaines applications particulières, des groupes de lettres (par exemple, AUTO, STOP) sont
utilisés comme symboles ou éléments de symbole.
Note 2 à l’article: Les lettres et les caractères numériques ne sont ni couverts par l’ISO/TC 145/SC 3 ni publiés
dans l’ISO 7000 à moins d’être intégrés dans des symboles graphiques.
3.2
icône
icône d’affichage numérique
représentation numérisée (pixélisée) d’un symbole graphique, habituellement utilisée sur un écran
électronique reconfigurable ou sur une interface utilisateur graphique
Note 1 à l’article: Un même symbole peut être représenté par plusieurs icônes, chacune ayant une taille, un
nombre de pixels ou une colorisation différents.
4 Généralités
4.1 Sauf indication contraire dans les articles suivants, les symboles doivent être utilisés conformément
au présent document.
4.2 Les symboles sélectionnés, qui sont présentés sous forme de contour dans le présent document,
peuvent utiliser un remplissage dans l’utilisation réelle afin de renforcer la clarté de la reproduction et
d’améliorer la perception visuelle de l’opérateur, sauf indication contraire notifiée pour les symboles
individuels et en conformité avec l’IEC 80416-3.
4.3 Les restrictions propres aux technologies de reproduction et de représentation peuvent nécessiter
un épaississement du trait ou d’autres modifications mineures des symboles. De telles modifications
sont autorisées si le symbole reste conceptuellement inchangé dans ses éléments graphiques de base et
s’il demeure facilement perceptible par l’opérateur.
4.4 Pour améliorer l’apparence et la perceptibilité d’un symbole graphique ou pour le coordonner avec
la conception du matériel où il sera apposé, il peut être nécessaire de modifier le symbole tel que décrit
dans l’IEC 80416-3 (par exemple, changer l’épaisseur du trait ou arrondir les angles du symbole). Ces
modifications sont autorisées sous réserve que les caractéristiques perceptibles essentielles du symbole
soient conservées.
4.5 Pour l’utilisation réelle, tout symbole doit être reproduit aussi grand que possible afin d’être
facilement perceptible par l’opérateur. Suivre l’IEC 80416-1 pour la taille appropriée des symboles. Il
convient que les symboles regroupés dans un indicateur ou sur un ensemble de commandes soient à la
même échelle que les repères en coin du symbole d’origine, comme illustré dans le présent document,
afin de préserver une bonne relation visuelle entre les symboles. Les symboles doivent être utilisés dans
l’orientation représentée dans le présent document, à moins qu’une rotation ou un effet d’image inverse
ne soient précisément autorisés pour les symboles individuels.
4.6 La plupart des symboles sont créés en utilisant une approche de montage globale dans laquelle
différents symboles et éléments de symbole sont combinés d’une manière logique pour produire un
nouveau symbole.
2 © ISO 2016 – Tous droits réservés

4.7 Dans certains cas, les symboles peuvent être utilisés de façon conjointe, sans toutefois être
combinés dans un symbole composite, afin de véhiculer la même signification que le symbole composite.
4.8 Les symboles ont généralement pour but de remplacer un ou plusieurs termes par une image
graphique ayant la même signification pour tous les opérateurs, quelle que soit leur langue maternelle.
Pour autant, l’emploi d’un symbole graphique dans le but d’identifier une commande ou un indicateur
n’interdit pas d’utiliser des termes en parallèle.
4.9 Si le symbole représente une machine ou des parties d’une machine en vue de côté, la machine doit
être présumée comme se déplaçant de la droite vers la gauche dans la zone du symbole. Si le symbole
représente une machine ou des parties d’une machine en vue de dessus, la machine doit être présumée
comme se déplaçant de bas en haut dans la zone du symbole.
4.10 Les symboles sur les commandes et les indicateurs doivent présenter un bon contraste par
rapport au fond. Un symbole blanc ou clair sur un fond noir ou sombre est préférable pour la plupart des
commandes. Les indicateurs peuvent utiliser soit un symbole blanc ou clair sur un fond noir ou sombre,
soit un symbole noir ou sombre sur un fond blanc ou clair, en fonction de l’alternative offrant la meilleure
perception visuelle. Lorsqu’une image de symbole est inversée (par exemple, noir pour blanc et vice
versa), cette inversion doit être réalisée sur l’ensemble du symbole.
4.11 Dans le cas de symboles coulés, moulés, appliqués en relief ou gravés sur une surface, les symboles
doivent pouvoir être distingués visuellement de la surface quelle que soit la couleur utilisée.
4.12 Les symboles doivent être situés sur ou à côté des commandes ou des indicateurs qu’ils identifient.
Lorsque plusieurs symboles sont nécessaires pour une commande, les symboles doivent être situés, par
rapport à la commande, de sorte que le mouvement de la commande vers le symbole produise l’action
décrite par ce symbole.
4.13 Les flèches utilisées dans les symboles doivent être conformes aux exigences de
l’IEC 80416-2. L’IEC 80416-1 doit être consultée pour les principes généraux de création des dessins
originaux de symboles. Il convient de se référer à l’IEC 80416-3 pour obtenir les lignes directrices
relatives à l’application des symboles.
4.14 Les numéros d’enregistrement ISO/IEC sont indiqués pour les symboles qui sont enregistrés dans
l’ISO 7000 ou l’IEC 60417.
NOTE Les dessins originaux de symboles sont soit approuvés et enregistrés par l’ISO/TC 145/SC 3 et publiés
dans l’ISO 7000, soit approuvés et enregistrés par l’IEC/SC 3C et publiés dans l’IEC 60417. Dans certains cas,
des symboles modifiés ou adaptés à l’application sont normalisés dans le présent document en lieu et place des
dessins originaux enregistrés.
4.15 Lorsque des lettres ou des chiffres sont utilisés dans un symbole, la police utilisée ne doit pas être
considérée comme définitive. Il est possible d’appliquer des polices différentes dans la mesure où les
lettres et les chiffres demeurent lisibles.
4.16 Les symboles référencés dans le présent document comportent des repères qui marquent les
angles du modèle de base carré de 75 mm de côté de l’IEC 80416-1. Les repères d’angle ne font pas
partie du symbole, mais sont représentés pour assurer une présentation uniforme de tous les symboles
graphiques.
5 Couleur
Lorsqu’elles sont utilisées sur des indicateurs lumineux, les couleurs suivantes doivent avoir la
signification indiquée ci-après:
— Rouge: défaut, sérieux dysfonctionnement ou état de fonctionnement nécessitant une attention
immédiate;
— Jaune ou ambre: état en dehors des limites normales de fonctionnement;
— Vert: conditions normales de fonctionnement.
6 Élaboration de nouveaux symboles
6.1 Avant d’élaborer un nouveau symbole, il convient de rechercher les symboles déjà normalisés ayant
une signification identique ou similaire. L’ISO 7000 et l’IEC 60417 (tous deux disponibles sous forme de
base de données) regroupent les symboles internationalement normalisés et peuvent se révéler utiles
pour rechercher les symboles appropriés qui ne figurent pas dans l’une des parties de l’ISO 3767 et pour
générer des concepts exploitables dans l’élaboration de nouveaux symboles.
6.2 Les nouveaux symboles doivent être élaborés conformément aux principes de l’ISO 3767-1:2016,
Annexe A. Il convient également de consulter l’ISO 80416-1 pour connaître les principes généraux de
la création de symboles. Les flèches doivent être telles qu’indiquées dans l’ISO 80416-2. Chaque forme
de flèche possède une signification bien précise, conformément à l’ISO 80416-2. Il convient de veiller
à utiliser la forme de flèche appropriée. Conformément aux directives de l’ISO 3767-1:2016, Annexe A
permet d’élaborer des symboles à la forme graphique et au contenu compatibles avec une normalisation
internationale et un enregistrement ISO 7000.
6.3 Les symboles proposés en vue de leur normalisation dans le présent document doivent inclure une
brève explication de leur fonction ou utilisation prévue.
NOTE L’IEC 80416-1 utilise le terme « description » pour ce type d’information et fournit des lignes
directrices pour la rédaction de descriptions concernant les symboles en attente de normalisation ISO 7000 ou
IEC 60417. Les descriptions des symboles normalisés dans le présent document peuvent être utilisées comme
exemples.
7 Adaptation de symboles sous forme d’icônes d’affichage numérique
Il est possible d’adapter les symboles afin de les utiliser comme icônes d’affichage numérique sur des
unités d’affichage visuel, telles que des indicateurs reconfigurables ou autres indicateurs électroniques.
Il convient que ces adaptations respectent les principes de l’ISO 80416-4. Il convient en outre de veiller
tout particulièrement à ce que les icônes d’affichage numérique conservent l’impression visuelle
du symbole dont elles sont dérivées. Les principes relatifs à l’emploi des couleurs dans les symboles
s’appliquent également à l’emploi des couleurs dans les icônes d’affichage numérique.
