Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that
are members of ISO or IEC participate in the development of International Standards through
technical committees established by the respective organization to deal with particular fields of
technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with ISO and IEC, also
take part in the work.
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 document 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 and IEC 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) or the IEC
list of patent declarations received (see http: //patents .iec .ch).
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/IEC JTC 1, Information technology,
Subcommittee SC 35, User interfaces.
This second edition cancels and replaces the first edition (ISO/IEC 13251:2004), which has been
technically revised.
The main changes compared to the previous edition are as follows:
— Addition of 69 new graphical symbols identified by the numbers 380.448; and
— Simplification of document view by avoiding repetition of the same technical contents in
different visualization.
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.

Introduction
A graphical symbol is defined as a visually perceptible figure used to transmit information
independently of language. It may be produced by drawing, printing or other means. The principles for
the creation of graphical symbols for use on equipment are described in IEC 80416-1.
To respond to the increasing international interest in the design and use of graphical symbols, this
collection presents a certain number of graphical symbols for use on office equipment.
Reference should be made to IEC 80416-3 for rules for the application and modification of the graphical
symbols and for supplementary information.
The process of creating new symbols is described in ISO/IEC Directives, Part 1 and Consolidated
ISO Supplement: 2018, Annex SH and IEC Supplement (Annex SL, Processes for the validation of new
graphical symbols for use on equipment).

machines.
These graphical symbols are also used in other application areas if appropriate.
NOTE The graphical symbols in this document are collections of relevant graphical symbols standardized in
IEC 60417 and ISO 7000.

be consulted.
6 Graphical symbols for office equipment
001 “ON” (power)
To indicate connection to the mains, at least for mains switches or their positions, and all those cases
where safety is involved.
The meaning of this graphical symbol depends upon its orientation.
See also symbol IEC 60417-5264.
IEC 60417-5007
002 “OFF” (power)
To indicate disconnection from the mains, at least for mains switches or their positions, and all those
cases where safety is involved.
See also symbol IEC 60417-5265.
IEC 60417-5008
003 “ON”/“OFF” (push-push)
To indicate connection to or disconnection from the mains, at least for mains switches or their positions,
and all those cases where safety is involved. Each position, “ON” or “OFF”, is a stable position.
IEC 60417-5010
004 “ON”/“OFF” (push button)
To indicate connection to the mains, at least for mains switches or their positions, and all those cases
where safety is involved. “OFF” is a stable position, whilst the “ON” position only remains during the time
the button is depressed.
IEC 60417-5011
005 “ON” for a part of equipment
To indicate the "ON” condition for a part of equipment, if the symbol IEC 60417-5007 cannot be used, for

example, to identify the “OFF” position of a switch.
To be used in association with the symbol IEC 60417-5264.
IEC 60417-5265
007 Stand-by or preparatory state for a part of equipment
