IEC/TC 3 - Documentation, graphical symbols and representations of technical information
Standardization in the field of documentation, graphical symbols and representations of technical information, covering 1) Rules, principles and methods focusing on machine sensible representation of information. This includes but is not limited to: - Definition and identification of classes and properties (e.g. sematic data), - ontologies and data dictionaries (e.g. CDD), - Information models for structuring of technical data and document management, - information exchange based on existing communication means. It includes definition, co-ordination and management of the information required during the whole life cycle of a device, system, or plant, also covering aspects of documentation. 2) Rules, principles and methods focusing on human sensible representation of the information. This includes but is not limited to: - presentation of information in documentation, - graphical symbols for use in documentation, - graphical symbols for the human interaction with equipment. The standards deal with the presentations and graphical symbols as shown in documents or on equipment, independently of their forms of representation, analogue or digital, but may also include requirements for the development of documentation. 3) Rules, principles and methods for general and safety related marking, identification and arrangement of information in electrical installations, equipment and man-machine interfaces. This includes but is not limited to: - the meanings of colours and alternative means, when used for marking and identification, - the arrangement of indicating devices and actuators, - coding principles for indicating and actuating devices, - terminal designation of electrical and electronic components, apparatus and equipment, - designation of certain designated conductors, - marking of electrical and electronic equipment with ratings related to supply and to its properties, - marking of bare and insulated conductors.
Structures d'informations, documentation et symboles graphiques
Elaborer des normes dans le domaine de l'électrotechnique et les domaines connexes portant : 1) sur les méthodes et les règles associées à l'interprétation humaine de l'information, ce qui intéresse : - la présentation de l'information dans la documentation technique, - les symboles graphiques utilisables dans la documentation technique, - les symboles graphiques utilisés dans les interactions homme/matériel. 2) sur les méthodes et les règles associées au traitement de l'information sous forme accessible à l'ordinateur, ce qui intéresse : - les modèles informatisés qui servent à la documentation technique et à l'échange d'informations techniques ainsi que l'identification des exigences complémentaires de ces modèles, - la définition des types d'éléments de données et des ensembles de données utilisables avec les modèles informatisés et la documentation technique, ainsi que pour les échanges d'informations techniques. Il comprend la définition et la coordination des informations voulues au cours de la durée entière du cycle de vie d'un dispositif, système ou installation. Ces travaux seront effectués en étroite collaboration avec les organisations internationales et les comités techniques compétents.

The International Organization for Standardization (ISO) is an independent, non-governmental international organization that develops and publishes international standards. Founded in 1947 and headquartered in Geneva, Switzerland, ISO brings together experts from 170+ member countries to share knowledge and develop voluntary, consensus-based standards that support innovation and provide solutions to global challenges.
A Technical Committee (TC) in ISO is a group of experts responsible for developing international standards in a specific technical area. TCs are composed of national member body delegates and work through consensus to create standards that meet global industry needs. Each TC may have subcommittees (SCs) and working groups (WGs) for specialized topics.
