ISO Bulletin 2003/2

Each ISO technical committee is responsible for the selection or creation of graphical symbols within its own field of interest. Graphical symbols may form the main subject of an International Standard or a single symbol or several symbols may appear as part of a standard covering wider aspects of the subject to which the symbol(s) refer.

Sharing the graphical symbols standardization process
The ISO Technical Management Board has assigned overall responsibility for standardisation in the field of graphical symbols from ISO/TC 145, Graphical symbols, and to ISO/TC 10/SC 10, Technical product documentation (tpd) symbols.

Their separate and distinct responsibilities are outlined below:

ISO/TC 10/SC 10, Graphical symbols for use in technical product documentation (tpd), holds overall responsibility for standardisation in the field of graphical symbols for technical product documentation (tpd). This responsibility includes:

- maintenance of ISO 81714-1, Design of graphical symbols for use in the technical documentation of products - Part 1: Basic rules, in cooperation with IEC (International Electrotechnical Commission);

- standardisation of graphical symbols to be used in technical product documentation, coordinated with IEC;

- establishing and maintaining a database for graphical symbols including management of registration numbers.

Included in its brief is the standardisation of symbols for use in diagrams and pictorial drawings.

The Secretariat of ISO/TC 10/SC 10 is supported by a maintenance group. Any committee identifying the need for new or revised graphical symbols shall as soon as possible, submit their proposal to the Secretariat of ISO/TC 10/SC 10 for review and - once approved - allocation of a registration number.

ISO/TC 145, Graphical symbols, holds overall responsibility for standardisation of graphical symbols in the field of public information, safety signs and for use on equipment. This responsibility includes:

- progressing work items through ISO/TC 145 to respond to general needs for graphical symbols across all areas of the application of graphical symbols within the scope of ISO/TC 145;

- progressing work items through ISO/TC 145 to define design principles and quality attributes of graphical symbol-based communications;

- coordinating and advising on the work items/projects of other committees within ISO for work items involving graphical symbols;

- coordinating and advising on the work on graphical symbols of other standards organizations with official liaison to ISO.

ISO/TC 145 has allocated and distributed these responsibilities as follows:

- ISO/TC 145/SC 1, Graphical symbols in the field of public information.
- ISO/TC 145/SC 2, Graphical symbols in the field of safety signs.
- ISO/TC 145/SC 3, Graphical symbols for use on equipment.

The review and coordination role of ISO/TC 145 applies to all committees that undertake the responsibility for creation and standardisation of graphical symbols within their own particular fields.

Any committee identifying the need for new or revised graphical symbols should, as soon as possible, submit their proposal to the Secretariat of the appropriate ISO/TC 145 subcommittee for review and - once approved - allocation of a registration number.

ISO/TC 145, Graphical symbols, in accordance with its scope, holds general responsibility for the review and coordination for all graphical symbols. The Secretariats of the subcommittees of ISO/TC 145 maintain a data bank of symbols incorporating both the standardized symbols already registered and those in the course of standardisation.

ISO/TC 10/SC 10, Technical Product Documentation symbols, by agreement with and in collaboration with ISO/TC 145, and in accordance with its scope, ensures the review and coordination of graphical symbols used in technical product documentation. Such coordination is carried out in close cooperation with IEC/TC 3.
