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 of the voluntary nature of standards, the meaning of ISO specific terms and

expressions related to conformity assessment, as well as information about ISO's adherence to

the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

www .iso .org/ iso/ foreword .html.

This document was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 38,

Motorcycles and mopeds.

This third edition cancels and replaces the second edition (ISO 6727:2012), which has been technically

revised.
The main changes compared to the previous edition are as follows:

— the scope has been expanded to mopeds, the third edition of ISO 4129:2012 which was technically

revised has been integrated, and
— new symbols have been added due to technology changes.

Any feedback or questions on this document should be directed to the user’s national standards body. A

complete listing of these bodies can be found at www .iso .org/ members .html.

4 General

4.1 The symbols shall be such that, when viewed by the rider, from their normal seated position or

normal operated position, they are recognizable as shown in Annexes A to O.

4.2 The symbol shall be placed on, or adjacent to, the control or tell-tale to be identified. Where this

is not possible, the symbol and the control or tell-tale shall be joined by a continuous line as short as

possible

4.3 The symbols and signs shall be as given in Annexes A to L and Annex N. Additional symbols are

given in Annexes M and O. Minor deviations to the symbols and signs are permitted, provided they are

necessary to reproduce an accurate representation to the rider's line of sight.

NOTE Additional annexes can be included in future editions of this document if necessary.

4.4 In developing the symbols and signs shown in Annexes A to O, legibility factors such as line

thickness, gaps between lines, symbol and arrow shapes, etc. were carefully considered. Modifications

that improve legibility are permitted in the circumstances specified in 4.4.1, 4.4.2 and 4.4.3. When

modifying symbol elements, the graphic designer should consult IEC 80416-1, ISO 80416-2, IEC 80416-3,

and ISO 80416-4.

4.4.1 Limitations inherent in some reproduction and display technologies can require increased line

thickness or other minor modifications of symbols. Such modifications are acceptable provided the

symbol remains unchanged in its basic graphical elements and is easily discernible by the operator.

4.4.2 Additionally, 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 change the line thickness

or to round off the corners of the symbol. The graphic designer is normally free to make such changes

provided that the essential perceptible characteristics of the symbol are maintained.

4.4.3 The graphic designer may render a symbol in either outline or solid form unless this is otherwise

prohibited by the symbol description.

4.5 The vehicle shapes shown in this document are not intended to be restrictive. Modifications to

vehicle shape may be introduced by designers in order to better represent the true exterior shape of a

given vehicle. Except for vehicle shape, no other symbol element shall be changed, except as provided in

4.4 or in the specific symbol's description.

4.6 If, in a symbol, a vehicle or parts of a vehicle are shown in a side view, a vehicle driving from right

to left shall be used.

4.7 For actual use, all symbols shall be reproduced large enough to be easily discernible by the operator.

See IEC 80416-3 for guidelines on the proper sizing of symbols. Symbols shall be used in the orientations

shown in this document unless otherwise noted for individual symbols.

4.8 For most controls, a light symbol on a dark background is preferred. Displays may use either a light

symbol on a dark background or a dark symbol on a light background, depending on which alternative

provides the best visual perception. When a symbol image is reversed (for example black to white and

vice versa), it shall be done for the entire symbol.

4.9 Each symbol used for the identification of a tell-tale, control or indicator shall stand out clearly

against the background.

4.10 Letters and numerals may be used as symbols, but are not registered by ISO/TC 145, Graphical

symbols, or published in ISO 7000. For example, the letters R, N, D, listed as symbols ,

have the meaning indicated when used in association with transmission gear controls and displays on

road vehicles. The fonts shown in this document are not intended to be restrictive; other fonts may be

substituted provided that legibility is maintained.
4.11 “Failure” or “malfunction” may be conveyed in two ways:
a) Base symbol combined with a colour code according to 5.1;

b) Base symbol combined with failure symbol ; optionally, an appropriate colour code in

accordance with 5.1 may be added.

4.12 ISO/IEC registration numbers are shown for symbols in this document where applicable.

Registration numbers below 5 000 refer to ISO 7000. Registration numbers above 5 000 refer to

IEC 60417. Artwork in this document might differ from the artwork shown in IEC 60417, ISO 7000 or the

IEC/ISO database on graphical symbols for use on equipment. In this case, the artwork in this document

shall be used.

4.13 The symbol numbers not represented are reserved for those symbols still under consideration at

the time of publication of this document. It is envisaged that the status of these symbols and the numbers

will be resolved by the next revision of this document.

4.14 Symbols in the annexes (except Annex O) of this document are presented at 32 % of original size.

The grid marks “∟” denote the corners of the original 75 mm square. The grid marks are not part of the

symbol but are provided to ensure consistent presentation of all symbol graphics.

4.15 New symbols for functions not yet covered in this document should be constructed using symbols

or elements of symbols from this document in a logical manner, keeping the coherence with other

symbols already published.
5 Colour

5.1 When the following colours are used on the optical tell-tales, they shall have the meaning

indicated below:

— red: danger to persons or very serious damage to equipment, immediate or imminent.

— amber (yellow): caution, outside normal operating limits, vehicle system malfunction, damage to

vehicle likely, or other condition which can produce hazard in the longer term.

— green: safe, normal operating condition (except if blue or amber is required by annexes).

A given symbol may be shown in more than one of these colours in order to convey the indicated

meanings.

5.2 Certain colours are used for specific tell-tales (refer to “symbol description/application” column in

the annexes):
— blue: e.g. high beam, main beam.
— green: e.g. turn signals.
— amber (yellow): e.g. failure of anti-lock brake system.
— red: e.g. hazard warning.
