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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. 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.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 81714-1 was prepared jointly by Technical Committees ISO/TC 10, Technical product documentation,
Subcommittee SC 10, Process plant documentation and tpd-symbols, and IEC/TC 3, Information structures,
documentation and graphical symbols. The draft was circulated for voting to the national bodies of both ISO
and IEC.
This second edition of ISO 81714-1 cancels and replaces the first edition (ISO 81714-1:1999), which has been
technically revised.
ISO 81714 consists of the following parts, under the general title Design of graphical symbols for use in the
technical documentation of products:
⎯ Part 1: Basic rules
IEC 81714 consists of the following parts, under the general title Design of graphical symbols for use in the
technical documentation of products:
⎯ Part 2: Specification for graphical symbols in a computer sensible form, including graphical symbols for a
reference library, and requirements for their interchange
⎯ Part 3: Classification of connect nodes, networks and their encoding

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.
NOTE Supplementary requirements for graphical symbols used in advanced computer-aided design systems are
specified in IEC 81714-2 and IEC 81714-3.
2 Normative references
The following referenced documents are indispensable for the application of this document. For dated
references, only the edition cited applies. For undated references, the latest edition of the referenced
document (including any amendments) applies.
ISO 129-1, Technical drawings — Indication of dimensions and tolerances — Part 1: General principles
ISO 6428, Technical drawings — Requirements for microcopying
ISO/IEC 8859 (all parts), Information technology — 8-bit single-byte coded graphic character sets
ISO/IEC 10367, Information technology — Standardized coded graphic character sets for use in 8-bit codes
ISO/IEC 10646, Information technology — Universal Multiple-Octet Coded Character Set (UCS)
ISO 80000-2, Quantities and units — Part 2: Mathematical signs and symbols to be used in the natural
sciences and technology
3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
3.1
graphical symbol
visually perceptible figure with a particular meaning used to transmit information independently of language
[6]
[ISO 17724:2003 , 31]
NOTE 1 The graphical symbol may represent objects of interest, such as products, functions or requirements for
manufacturing, quality control, etc.
NOTE 2 A graphical symbol is not to be confused with the simplified representation of products which is normally
drawn to scale and which can 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 can be used for positioning and transformation, e.g. by creation of a mirror image, rotation,
and displacement.
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
3.5
terminal line
line of a graphical symbol ending at a connect node
NOTE Most graphical symbols of non-electric character are not provided with terminal lines; most graphical symbols
of electric character are provided with terminal lines.
3.6
text
data in the form of characters, symbols, words, phrases, paragraphs, sentences, tables, or other character
arrangements, intended to convey a meaning, and whose interpretation is essentially based upon the reader's
knowledge of some natural language or artificial language
[3]
[ISO/IEC 2382-1:1993 , 01.01.03]
3.7
arc
curved line with no inflection point
3.8
variant
〈graphical symbols〉 alternative graphical symbol design for a given referent
[6]
[ISO 17724:2003 , 79]
EXAMPLE An identified orientation of a graphical symbol with regard to the flow direction or transfer direction.
NOTE A variant can be based on the rotation and/or creation of a mirror image of the corresponding symbol, together
with possibly other modifications such as relocation of inputs and outputs and reorientation of text.
4 Markers
In this part of ISO 81714, the marker shown in Figure 1 is used to illustrate positions of connect nodes.
