IEC 80416 3 Edition 1 1 2011 10 INTERNATIONAL STANDARD NORME INTERNATIONALE Basic principles for graphical symbols for use on equipment – Part 3 Guidelines for the application of graphical symbols Pri[.]
Equipment
Graphical symbols can be produced through various methods such as printing, engraving, embossing, or molding on equipment The technology employed to create and apply these symbols can affect their size and appearance It may be necessary to adjust the original symbol to maintain visual clarity while preserving its intended meaning.
Screens and displays
Symbol originals may need to be modified to take into account restrictions imposed by appearing on a screen or display In this application, ISO 80416-4 shall be taken into consideration
NOTE 1 ISO 80416-4 (under consideration) gives supplementary guidelines for the adaptation of graphical symbols for use on screens and displays (icons)
NOTE 2 IEC 60073 gives basic and safety principles for man-machine interface on screens and displays.
Supporting documentation
Graphical symbols reproduced in supporting documentation shall convey the same graphical impression as those used on the equipment.
International Standards
International Standards developed by technical committees that include standardized or modified graphical symbols for specific applications must display these symbols alongside their registration number and title.
In cases where modified graphical symbols in accordance with this part of IEC 80416 are adopted, the text "modified" shall be shown under the registration number
NOTE International standards may also contain graphical symbols for diagrams In such cases, IEC 60617 database and ISO/FDIS 14617 should be consulted
5 Size of graphical symbols in use
Symbol originals created on the basis of IEC 80416-1 and ISO 80416-2 and standardized in
IEC 60417 and ISO 7000 have a visual impression of size corresponding to the nominal size
50 mm The symbol original to be applied on equipment may therefore be reduced or enlarged to obtain a graphical symbol in a desired size
To ensure visual clarity, the minimum size S (mm) of a reproduced graphical symbol, whether reduced or enlarged, should correspond to the nominal size of 50 mm and be determined based on the intended viewing distance L (mm) using a specific equation.
6 Modification of symbol originals for application
Modification according to design
To meet the design requirements of equipment, it is permissible to make several adjustments, including changing line thickness, rounding corners, filling areas, and interrupting crossing lines Additionally, one may adapt the distances between graphical elements, modify the relative proportions of these elements, and alter the type of arrow used.
When multiple graphical symbols are used together, it is essential and permissible to adjust their sizes and positions to create a visually balanced appearance on the equipment.
These changes shall only be made to the extent that the basic communicative characteristics of the graphical symbol remain unchanged.
Line thickness
The thickness of the lines may be changed as in the example in figure 1
Stand-by IEC 60417-5009 applied with different line thickness
Figure 1 – Example of different line thickness
Rounded corner of graphical symbols
Rounded corners are permitted as in the example in figure 2
Patient support, rotation about an orthogonal axis
IEC 60417-5399 applied with rounded corners
Figure 2 – Example of rounded corner
Filled areas
White areas may be filled as in the example in figure 3
IEC 60417-5459: Eject IEC 60417-5459 applied with filled areas
Figure 3 – Example of filled areas
Interruption of crossing lines
Crossing lines may be interrupted as in the example in figure 4
Colour video output IEC 60417-5530 applied with interrupted line
Figure 4 – Example of interrupted lines
Modification of arrow type
The arrow type may be modified as in the examples given in Figure 11
A graphical symbol's meaning can be negated by using a 2 mm thick cross formed by two continuous diagonal bars at right angles, as specified in IEC 80416-1, section 6.9 For visual clarity, the angle where the diagonal bars intersect may deviate from 90 degrees, as illustrated in figure 5.
Graphical symbols registered in ISO 7000 and IEC 60417 can have their meanings negated upon application It is essential that the method and interpretation of this negation align with the guidelines set forth in IEC 80416-1:2008, section 7.9.
Print out ISO 7000-0793 applied with negation cross for “Print out, cancel”
Figure 5 – Example of application of negation for a standarized graphical symbol
The red circle with the red negation bar as defined in ISO/FDIS 3864-1:2001 for safety applications shall not be used for negation of graphical symbols for use on equipment
According to ISO 3864-1, a circle with a diagonal bar symbolizes a 'prohibition' This design, regardless of color—including black and white—must exclusively represent prohibition and should not be used to convey any other meaning.
In the original symbol, two arrowheads indicate movement in opposite directions; however, one arrowhead can be omitted to signify movement in a single direction, as illustrated in figure 6.
(b) IEC 60417-5964 applied with closed arrow heads
(c) IEC 60417-5964 applied with filled arrows and no arrow shafts
Patient support, orthogonal movement to its plane
IEC 60417-5395 applied to refer to single direction movement meaning “Patient support, vertical movement, up”
IEC 60417-5395 applied to refer to single direction movement meaning “Patient support, vertical movement, down”
Figure 6 – Example of application to single direction movement
Alternative forms of arrow may be used in line with the principles of ISO 80416-2
9 Change in meaning depending on orientation of graphical symbol
Orientation
Graphical symbols should normally be used in the orientation specified in the symbol original
However, graphical symbols may be used in any orientation providing that the original meaning is retained
The orientation can be adjusted to meet the equipment requirements or the specified reference system, provided there is no conflict of meaning, as illustrated in Figure 7.
In the absence of conflicting meanings, the orientation of the graphical symbol can be altered, or it may be displayed in a mirrored position to accommodate the equipment or reference system, as illustrated in Figures 7 and 12.
Mixing of substances IEC 60417-5657 rotated for mixing of substances
Figure 7 – Example of a graphical symbol the meaning of which is independent of its orientation
The graphical symbol must be used exclusively in the specified orientation, as its meaning is dependent on this arrangement, as illustrated in figure 8.
Figure 8 – Example of a graphical symbol the meaning of which depends upon its orientation
In some instances, altering the orientation can signify a change in meaning, as illustrated in figure 9, where IEC 60417-5108 represents both "fast run forward" and "fast run rewind" based on its orientation.
Fast run; fast speed IEC 60417-5108B applied to refer to “Fast run, rewind”
Figure 9 – Example of a graphical symbol the meaning of which depend upon its orientation
Application dependent orientation
The interpretation of graphical symbols can vary based on their orientation and context, making it essential to prevent ambiguity For instance, symbols depicted in figure 10 may be misread when used on equipment lacking a fixed orientation or on rotating controls like levers and wheels.
In these instances, it is essential to display the graphical symbol alongside a reference indicating its intended orientation A commonly accepted approach for this orientation reference is to position a dot in the lower right corner of the graphical symbol.
Plus; positive polarity (with orientation reference)
Minus; negative polarity (with orientation reference)
Figure 10 – Example for a reference to the intended orientation of a graphical symbol to avoid ambiguity
Glare prevention, exterior mirror, horizontal
ISO 7000-2674, applied mirrored for right hand side mirror
The primary meaning of a graphical symbol is independent of its representation in colour
Color should be used purposefully rather than arbitrarily, with particular attention given to red and yellow due to their significant implications in safety applications, as outlined in ISO/FDIS 3864-1:2001 and ISO/CD 3864-2:2001.

PRINCIPES ÉLÉMENTAIRES POUR LES SYMBOLES GRAPHIQUES
UTILISABLES SUR LE MATÉRIEL – Partie 3: Guide pour l’application des symboles graphiques
The International Electrotechnical Commission (IEC) is a global standards organization comprising national electrotechnical committees Its primary goal is to promote international cooperation in standardization within the fields of electricity and electronics To achieve this, the IEC publishes international standards, technical specifications, technical reports, publicly accessible specifications (PAS), and guides, collectively referred to as "IEC Publications." The development of these publications is entrusted to study committees, which allow participation from any national committee interested in the subject matter Additionally, international, governmental, and non-governmental organizations collaborate with the IEC in its efforts The IEC also works closely with the International Organization for Standardization (ISO) under conditions established by an agreement between the two organizations.
Official decisions or agreements by the IEC on technical matters aim to establish an international consensus on the topics under consideration, as each study committee includes representatives from the relevant national IEC committees.
The IEC publications are issued as international recommendations and are approved by the national committees of the IEC The IEC makes every reasonable effort to ensure the technical accuracy of its publications; however, it cannot be held responsible for any misuse or misinterpretation by end users.
To promote international consistency, the national committees of the IEC commit to transparently applying IEC publications in their national and regional documents as much as possible Any discrepancies between IEC publications and corresponding national or regional publications must be clearly stated in the latter.
The IEC does not issue any conformity certificates itself Instead, independent certification bodies offer conformity assessment services and, in certain sectors, utilize IEC conformity marks The IEC is not responsible for any services provided by these independent certification organizations.

Graphic symbols are visually recognizable drawings used to convey information regardless of language They serve a wide range of functions on materials, and the design of symbol families for specific locations or identical materials is crucial Clarity is essential, especially when symbols are reduced to small sizes Therefore, there is a need to standardize the principles for creating graphic symbols to ensure visual clarity, maintain consistency, and enhance recognition.
Matériel
Graphic symbols can be printed, engraved, stamped, or molded onto materials The technology used to reproduce and apply a graphic symbol on a device can alter its size and appearance Modifications to the original symbol may be necessary to ensure visual clarity, provided that the original meaning is preserved.
Ecrans et afficheurs
It may be necessary to consider potential restrictions imposed by their display on screens or indicators In this context, ISO 80416-4 should be taken into account.

NOTE Les normes internationales peuvent aussi contenir des symboles graphiques pour schémas Il convient de consulter la base de données CEI 60617 et ISO/FDIS 14617 dans de tels cas
5 Taille des symboles graphiques utilisés
The original symbol, based on IEC 80416-1 and ISO 80416-2 and standardized according to IEC 60417 and ISO 7000, has a visual size corresponding to a nominal dimension of 50 mm However, this original symbol can be resized, either reduced or enlarged, to achieve the desired graphic dimension for use on equipment.
The minimum reduction or maximum enlargement of size S (mm), corresponding to the nominal dimension of 50 mm, for a graphic symbol reproduced in accordance with the visual distance L (mm) can be determined by the following equation to ensure visual clarity.
6 Modification des symboles originaux pour utilisation
Modification selon la conception
To meet design requirements for materials, it is permissible to make several modifications, including: a) adjusting the line width; b) rounding corners; c) filling empty spaces in graphic symbols; d) removing line intersections; e) adjusting distances between graphic elements; f) modifying the relative proportions of graphic elements; and g) changing the type of arrow.
When multiple graphic symbols are used together, it may be necessary and permissible to adjust their size and relative position to achieve a balanced appearance on the material.
Ces modifications doivent seulement être effectuées dans la mesure ó les significations de base du symbole graphique demeurent inchangées.
Largeur des traits

9 Changement de signification dépendant de l’orientation des symboles graphiques
Graphical symbols should typically be used according to the orientation specified by the original symbol However, they can be utilized in any other orientation as long as the original meaning is preserved.
If there is no discrepancy in meaning, the orientation can be adjusted to accommodate the requirements of the given material or reference system, as illustrated in Figure 7.
If there is no discrepancy in meaning, the orientation can be altered, or the graphic symbol or part of it can be presented in a mirrored position to meet the requirements of the specific material or reference system, as demonstrated in Figures 7 and 12.

Figure 8 – Exemple de symboles graphiques dont la signification dépend de leur orientation
Figure 12 – Exemple de position miroir
In certain instances, the orientation can be altered to convey a change in meaning, as illustrated in Figure 9, where IEC 60417-5108 is utilized for "rapid advance" and "rapid return" depending on its orientation.

Figure 9 – Exemple de symboles graphiques dont la signification dépend de leur orientation
Utilisation dépendant de l'orientation
The meaning of each graphic symbol can vary based on its orientation within a specific context, necessitating careful consideration to avoid ambiguity For instance, the graphic symbols in Figure 10 may be misinterpreted if used on devices without a fixed orientation or on rotating levers, steering wheels, and similar control surfaces.
Rétroviseur extérieur, anti- éblouissement, type horizontal
ISO 7000-2674, appliqué en miroir pour le rétroviseur droit
In such cases, it is essential to reproduce the graphic symbol with a reference to the desired orientation An accepted method for providing an orientation reference is to place a point at the bottom right corner of the graphic symbol.
Plus; polarité positive (avec référence d'orientation)
Moins; polarité négative (avec référence d'orientation)
