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.
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 ISO documents 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 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).
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/

This document was prepared by Technical Committee ISO/TC 10, Technical product documentation,
Subcommittee SC 1, Basic conventions, in collaboration with the European Committee for Standardization
(CEN) Technical Committee CEN/SS F01, Technical drawings, in accordance with the Agreement on
technical cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 7083:1983), which has been technically
revised.
The main changes to the previous edition are as follows:
— added symbols for standards under ISO/TC 10 and ISO/TC 213.

Introduction
This document is a collection of all the current symbols used in technical product documentation,
predominantly created in ISO/TC 10 and ISO/TC 213. The symbols are indexed to the individual
standards in which they were created and implemented. The ISO/TC 10/SC 1 validation process ensures
the harmonization of symbols.
When developing new symbols for use in technical drawings, new symbols are submitted to ISO/TC 10
for review. ISO/TC 10 will confirm that a duplicate symbol with a different meaning does not exist
and will add the new symbol to this document once the originating standard has been approved and
published.
The following is a description of the process used for incorporating a new symbol:
a) The originator fills in the new symbol application form.
b) The originator attaches the symbol graphics file per the accepted graphics formats in the form.
c) The originator sends the application and graphics file to ISO/TC 10/SC 1.
d) ISO/TC 10/SC 1 forwards the documents to the validation team (appointed group of experts).
e) The validation team reviews the application and symbol according to the following areas:
— justification for new symbol;
— design;
— conformity with ISO 81714-1;
— duplication and similarity to existing and registered symbols.
f) The validation team prepares their report and sends the application documents back to
ISO/TC 10/SC 1. Rejected proposals are sent back to the originator with an attached cause of
rejection.
g) If the new symbol request is approved, the originator is notified and the symbol is appointed a
registry number and submitted to ISO Central Secretariat for registration and publication on the
ISO Online browsing platform: https:// www .iso .org/ obp.
h) The approved new symbol is added to the list of symbols to be added to the next revision of this
document.
INTERNATIONAL STANDARD ISO 7083:2021(E)
Technical product documentation — Symbols used in
technical product documentation — Proportions and
dimensions
1 Scope
This document specifies the recommended proportions for the symbols used in technical product
documentation. It gives recommended dimensions based on the grid related to the line width to be
used.
This document does not apply to symbols used in process plant documentation, which are covered in
ISO 81714-1.
The proportions of the symbols are based on the standard heights of lettering given in ISO 3098-1.
