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.
Draft International Standards adopted by the technical committees are circulated to the member bodies for voting.
Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote.
International Standard ISO 81714-1 was prepared jointly by Technical Committees ISO/TC 10,
Technical drawings,
product definition and related documentation, ISO/TC 145, Graphical symbols, and IEC/TC 3, Documentation and
. Formal voting has taken place within both ISO and IEC.
graphical symbols
This first edition of ISO 81714-1 cancels and replaces ISO/IEC 11714-1:1996, which has been updated. It serves as
the basis for the design of graphical symbols in all fields of the technical documentation of products. Applications of
this part of ISO 81714 are, for example, future editions of IEC 60617 and ISO 14617.
In order to collect all requirements concerning relevant graphical symbols within one single numerical series,
ISO/TC 10 and IEC/TC 3, in conjunction with ISO/TC 145, agreed to publish all parts of this International Standard
within the 81714 series.
The Technical Management Board of ISO and the Committee of Action of IEC have decided that for each part of
this series, one organization shall be chosen responsible. The Technical Committees involved have agreed not to
change any part of International Standard 81714 without mutual agreement.
International Standard 81714 consists of the following parts, under the general title Design of graphical symbols for
use in the technical documentation of products:
ISO 81714-1 — Part 1: Basic rules
IEC 81714-2 —
Part 2: Specification for graphical symbols in a computer sensible form including graphical symbols
for a reference library, and requirements for their interchange
IEC 81714-3 —
Part 3: Classification of connect nodes, networks and their encoding
Further parts specific to individual subject field requirements are under consideration.

Design of graphical symbols for use in the technical
documentation of products —
Part 1:
Basic rules
1 Scope
This part of ISO 81714 specifies basic rules for the design of graphical symbols for use in the technical
documentation of products taking into account basic application needs.
2 Normative references
The following standards contain provisions which, through reference in this text, constitute provisions of this part of
ISO 81714. At the time of publication, the editions indicated were valid. All normative documents are subject to
revision, and parties to agreements based on this part of ISO 81714 are encouraged to investigate the possibility of
applying the most recent editions of the standards indicated below. Members of IEC and ISO maintain registers of
currently valid International Standards.
ISO 31–11:1992, Quantities and units - Part 11: Mathematical signs and symbols for use in the physical sciences
and technology.
ISO 129: 1985, Technical drawings - Dimensioning - General principles, definitions, methods of execution and
special indications.
ISO 6428 :1982, Technical drawings - Requirements for microcopying.
ISO/IEC 8859 (all parts), Information processing - 8-bit single-byte coded graphic character sets.
ISO/IEC 10367:1991, Information technology - Standardized coded graphic character sets for use in 8-bit codes.
ISO/IEC 10646–1:1993, Information technology - Universal Multiple-Octet Coded Character Set (UCS) - Part 1:
Architecture and Basic Multilingual Plane.
IEC 61286: 1995, Information technology - Coded graphic character set for use in the preparation of documents
used in electrotechnology and for information interchange.
3 Definitions
For the purposes of this part of ISO 81714, the following definitions apply.
3.1 graphical symbol
visually perceptible figure used to transmit information independently of language
NOTES —
1 The graphical symbol may represent objects of interest, such as products, functions or requirements for manufacturing, quality
control etc.
2 This is not to be confused with the simplified representation of products which is always drawn to scale and may look like a
graphical symbol.

3.2 reference point
origin of the coordinate system used in the description of all the graphical elements of the graphical symbol
NOTE - The reference point may be used for positioning and transformation, e. g. mirroring, turning, moving.
3.3 symbol family
set of graphical symbols with a common conception using graphical characteristics with specific meanings
3.4 connect node
location on a graphical symbol intended for connection
