BASIC PRINCIPLES FOR GRAPHICAL
SYMBOLS FOR USE ON EQUIPMENT –
Part 1: Creation of graphical symbols for registration
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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with an IEC Publication.

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 80416-1 has been prepared by IEC subcommittee 3C: Graphical

symbols for use on equipment, of IEC technical committee 3: Information structures,

documentation and graphical symbols.

This International Standard has been prepared in co-operation with ISO/TC145/SC 3.

It is published as a double logo standard.

This second edition cancels and replaces the first edition published in 2001. This edition

constitutes a technical revision.

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

edition:
a) Clause 8 in the previous edition is moved to Clause 4;
---------------------- Page: 9 ----------------------

b) Mandatory requirement for the line width in symbol originals is changed to 2 mm or 4 mm

(see 6 paragraph of 7.3);

c) For negation of a graphical symbol, a single diagonal bar is allowed in addition to two

diagonal bars at right angles;
d) A new meaning of negation “do not” is allowed;

e) Some freedom is given for use of the basic pattern such as for symbol originals to be

f) Annex A (normative) is newly introduced for provisions on title, description and notes;

g) The nature of notes is changed to be purely informative; and
h) Clause 10 in the previous edition is moved to Annex C (informative).
It has the status of a horizontal standard in accordance with IEC Guide 108.
The text of this standard is based on the following documents:
FDIS Report on voting
3C/1590/FDIS 3C/1609/RVD

Full information on the voting for the approval of this standard can be found in the report on

voting indicated in the above table. In ISO, the standard has been approved by 7 P members

out of 7 having cast a vote.

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

In order to collect all requirements concerning relevant basic principles within one single

numerical series, ISO technical committee 145: Graphical symbols and IEC technical

committee 3 agreed to publish all parts of this International Standard within the 80416 series.

The Technical Management Board of ISO and the Standardization Management Board of IEC

have decided that, for each part of this series, one organisation shall be chosen responsible.

The technical committees involved have agreed not to change any part of International

Standard 80416 without mutual agreement.

International Standard 80416 consists of the following parts, published under the general title

INTRODUCTION

A graphical symbol is defined as a visually perceptible figure with a particular meaning used

to transmit information independently of language. Graphical symbols are used on equipment

for a wide range of purposes. The understanding of such symbols can be improved by

consistent design. This is particularly important where families of symbols are used in one

location or on similar equipment. Good design also helps to maintain the legibility of symbols

when they are reduced to small dimensions for application. Thus, there is a need to

standardize the principles for creating graphical symbols for use on equipment to ensure

visual clarity, to maintain consistency and thereby to improve recognition.

International Standard 80416 is a multi-part standard which provides basic principles and

guidelines for the creation of graphical symbols for use on equipment (Parts 1 and 2) and also

principles and guidelines for adapting registered graphical symbols for use in practice (Parts 3

and 4).

This part of the multi-part standard addresses the basic rules used to create graphical

symbols for use on equipment, including line widths, negation elements, and the use of the

basic pattern. These design principles should be applied to all graphical symbols for use on

equipment. They are required for graphical symbols for registration in IEC 60417 and

ISO 7000.

It is recommended that symbol originals intended for specific fields of application are also

published in the appropriate technical product standard.

BASIC PRINCIPLES FOR GRAPHICAL
SYMBOLS FOR USE ON EQUIPMENT –
Part 1: Creation of graphical symbols for registration
1 Scope

This part of IEC 80416 provides basic principles and guidelines for the creation of graphical

symbols for registration, and provides the key principles and rules for the preparation of title,

description and note(s).
IEC 80416-1 applies to graphical symbols used:

– to identify the equipment or a part of the equipment (for example, controls or displays);

– to indicate functional states or functions (for example, on, off, alarm);
– to designate connections (for example, terminals, filling points);

– to provide information on packaging (for example, identification of content, instructions

for handling);

– to provide instructions for the operation of the equipment (for example, Iimitations of

use).
IEC 80416-1 does not apply to graphical symbols for:
– safety signs;
– use on drawings and diagrams;

– use in technical documentation of products and in technical product documentation;

– use for public information.

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.

4 Creation procedures

A designer considering the creation of a graphical symbol should become familiar with the

context of use of the intended symbol and then follow the following steps:

a) define clearly the purpose and meaning of the graphical symbol – i.e. will it be used to

identify equipment, indicate a functional state, designate a connection, provide information

on packaging, provide instructions on the operation of equipment, or a combination of

these;

b) identify the users of the graphical symbol (see ISO/IEC Guide 74) and any special needs

(see ISO/IEC Guide 71) and legal requirements;

c) ascertain whether an existing graphical symbol will fulfil the specifications and

requirements by checking IEC 60417 and ISO 7000;

d) where it is clear that a suitable graphical symbol does not exist, design a new graphical

symbol in accordance with the provisions of Clause 7 and Clause 8, and, where
appropriate:

1) identify any cultural and ethnic sensibilities and prohibitions that are relevant and take

them into account;

2) consider the effect on legibility of adding a negation cross or diagonal bar and make

any necessary adjustments to the design;

3) take into account the relationship with any other symbols, symbol elements and

symbol families and the related visual concept;

4) ensure that the design does not lend itself to an unintended or ambiguous meaning.

e) undertake an assessment of the legibility, perceptual quality, and comprehensibility of the

newly designed graphical symbol and adjust the design if the results are not satisfactory;

f) create a unique title for the graphical symbol; and

g) create a clear and unambiguous description of the graphical symbol and any operational

requirements (the latter will be included in the description).
Requirements for title, description and notes are given in Annex A.
5 Meaning
5.1 Assignment

The meaning assigned to each registered graphical symbol is the result of associating a title,

a symbol original and a description. The assigned meaning should be unambiguous and clear.

5.2 Orientation of the graphical symbols

Graphical symbols should normally be used in the orientation specified by the symbol

originals. Care should be taken to avoid ambiguity in the case of a graphical symbol where its

meaning depends on the orientation. Such ambiguity could occur, for instance, when

graphical symbols are placed on rotary knobs. Symbol originals should whenever possible be

created so as to preserve their meaning in any orientation as the example a) in Figure 1.

However, when the meaning of a graphical symbol does depend on its orientation, as in the

case of the examples b) in Figure 1, this shall be explicitly stated in the description of the

symbol original.

NOTE Designation systems for symbol originals in IEC 60417 and ISO 7000 are given in Annex C.

6 Combination of graphical symbols

To represent certain concepts, graphical symbols or graphical symbol elements may be com-

bined to form a new symbol original. The meaning assigned to the new graphical symbol shall

be consistent with the meanings of the individual graphical symbols or graphical symbol

elements. See the example shown in Figure 2.

7 Creation principles
7.1 Creation of symbol original

A symbol original shall be created within the basic pattern shown in Figure 3, taking into

account the requirements given in Clause 8. These guidelines and requirements apply equally

to graphical symbols submitted for registration to IEC 60417 and ISO 7000.
