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

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).
