BASIC PRINCIPLES FOR GRAPHICAL SYMBOLS
FOR USE ON EQUIPMENT –
Part 1: Creation of symbol originals
FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this international standard may be the subject
of patent rights. The 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.
This standard replaces ISO 3461-1 (1988) and IEC 60416 (1988).
The text of this standard is based on the following documents:
FDIS Report on voting
3C/600/FDIS 3C/654/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 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 Committee of Action 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.

This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
International Standard 80416 consists of the following parts, under the general title Basic
principles for graphical symbols for use on equipment:
Part 1: 2001, Creation of symbol originals (published by IEC)

Part 3, Guidelines for the application of graphical symbols (being prepared,
and to be published by IEC)
Part 4, Supplementary guidelines for the adaptation of graphical symbols for
use on screen and displays (icons) (under consideration)
The committee has decided that the contents of this publication will remain unchanged until
2003. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.

Introduction
A graphical symbol is a visually perceptible figure used to transmit information independently of
language. Graphical symbols are used on equipment for a wide range of purposes. For such
symbols, consistency in the design of families of symbols used in one location or on similar
equipment is an important issue, as is legibility when these symbols are reduced to small
dimensions. 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.
This multi-part standard addresses the basic rules used to create graphical symbols for use on
equipment, including line widths, form and use of arrows, negation elements, and use of the
basic pattern which serves as a guideline for drawing equipment symbols. These design
principles are required to be used for all graphical symbols for use on equipment: the
standardized graphical symbols of which are found in ISO 7000 and IEC 60417.

BASIC PRINCIPLES FOR GRAPHICAL SYMBOLS
FOR USE ON EQUIPMENT –
Part 1: Creation of symbol originals
1 Scope
International Standard 80416 series provides principles and guidelines for the creation of
symbol originals and the application of graphical symbols for use on equipment prepared within
ISO and IEC.
This Part 1 of the standard specifies the key principles for the creation of symbol originals for
use on equipment. In accordance with the intended meaning of the symbol originals, it contains
rules for design such as shape and size, and also for preparation of the accompanying texts.
This standard applies to graphical symbols used:
- to identify the equipment or a part of the equipment (for example, a control or display);
- 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).
This standard does not apply to symbol originals for:
- safety signs;
- use on drawings and diagrams;
- use in technical documentation of products and in technical product documentation;
- use for public information.
2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this International Standard. For dated references, subsequent
amendments to, or revisions of, any of these publications do not apply. However, parties to
agreements based on this International Standard are encouraged to investigate the possibility
of applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of IEC
and ISO maintain registers of currently valid International Standards.
