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/

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.

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.

2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements 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 3098-1, Technical product documentation — Lettering — Part 1: General requirements

3 Terms and definitions
No terms and definitions are listed in this document.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at https:// www .iso .org/ obp
— IEC Electropedia: available at http:// www .electropedia .org/
4 General conditions

The lettering used with the symbols shall be in accordance with the specifications of ISO 3098-1.

On any one drawing the height, line width and type of lettering of the symbols should be equal to those

applied for the dimensioning and other indications on that drawing.

The symbols and their lettering are produced by digital means or may be hand-written (using a rule

for drawing the frames) or executed by other appropriate methods (e.g. stencils, transfers, mechanical

drawing).
5 Dimensions

Recommended dimensions of the symbols with lettering type A are specified in Table 1; dimensions for

those with lettering type B are specified in Table 2.

The distances between the vertical strokes of the compartments and the inscriptions shall be at least

twice the line width, with a minimum of 0,7 mm.
6 Proportions

Examples for the proportions of the symbols for use with lettering type B, vertical or inclined, are

shown in Table 3 to Table 50. The values are not part of the symbols.

The configurations are depicted on a grid with a spacing equal to the line width. The design of the

inscribed characters is mostly not shown but shall be the same as in ISO 3098-1 for lettering type B,

vertical or inclined.

For the alternative lettering type A, vertical or inclined, appropriate grids should be used.

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 on 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 the following URL:

Introduction

This documentation is a collection of all the current symbols used on technical product documentation,

predominantly created in ISO/TC10 and ISO/TC213. The symbols are indexed to the individual standards

in which they are were created and which they are implemented. The ISO/TC10 SC1 validation processed

will be reactivated and ensure the harmonization of symbols

When developing new symbols for use on technical drawings, new symbols are submitted to TC10 for

review. TC10 will confirm that a duplicate symbol with a different meaning does not exist and will add

the new symbol to this standard once the originating standard has been approved and published.

The following is a description of the process used for incorporation of a new symbol:

1. Fill in the New Symbol Application Form.
2. Attach symbol graphics file per the accepted graphics formats in the form.
3. Send application and graphics file to TC 10/SC 1.

4. TC 10/SC1 forwards the documents to the Validation Team (appointed group of experts).

5. The Validation Team reviews the application and symbol according to the following areas:

• Justification for new symbol
• Design

• Compliance with ISO 81714-1, Design of graphical symbols for use in the technical

documentation of products - Part 1: Basic rules
• Duplication and similarity to existing and registered symbols

6. The Validation Team prepares their report and the application documents back to TC 10/SC 1.

Rejected proposals are sent back to originator with attached cause of rejection.

7. If 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 in ISO/ OBP.

8. The approved new symbol is added to the list of symbols to be added in the next revision of ISO 7083.

Technical Product Documentation — Symbols used on
technical product documentation — Proportions and
dimensions
1 Scope

This document specifies the recommended proportions for the symbols used on technical product

documentation. It gives recommended dimensions based on the grid related to the line width to be used.

This standard does not apply to symbols used in process plant documentation which is covered in ISO

81714-1.

The proportions of the symbols are based on the standard heights of lettering given in IS0 3098-l.

2 Normative references

The following documents are referred to in the text in such a way that some or all of their content

constitutes requirements 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 3098-1, Technical product documentation - Lettering - Part 1: General requirements

3 Terms and definitions
No terms and definitions are listed in this document.

ISO and IEC maintain terminological databases for use in standardization at the following addresses:

— ISO Online browsing platform: available at http://www.iso.org/obp
— IEC Electropedia: available at http://www.electropedia.org/
4 General conditions

The lettering used with the symbols shall be in accordance with the specifications of IS0 3088-l.

It is recommended that on any one drawing the height, line width and type of lettering with the symbols

be equal to those applied for the dimensioning and- other indications on that drawing.

The symbols and their lettering are produced by digital means or may be hand-written (using a rule for

drawing the frames) or executed by means of other appropriate methods (for example, stencils, transfers,

mechanical drawing)
