IEC 60617 Graphical symbols for diagrams is since long well established, and implemented in most countries and regions in the world.
To support the management of IEC 60617 it has, as the first IEC standard, been converted into database form, accessible over the Internet. The content of the database is the standard. This allows not only better access, but also improved - quicker - maintenance. See the present entry page. The database requires subscription for access.
The database contains presently approximately 1835 symbols corresponding to the content of the former 13 parts of the printed standard, plus some extensions.
The market for the standards in this area has traditionally been design and engineering companies for electrotechnical equipment, systems and installations. With the use of CAD systems today a new market is possible to explore, and that is the CAD system suppliers. This, however, will require that the symbols are delivered electronically as symbol libraries, with associated functionality, easily adaptable to and processible in different design and engineering systems. Basic rules for the design of graphical symbols for in this context are provided in
IEC/ISO 81714 Design of graphical symbols for use in the technical documentation of products: ISO 81714-1 Part 1: Basic rules, IEC 81714-2 Part 2: Specification for graphical symbols in a computer sensible form, including graphical symbols for a reference library, and requirements for their interchange and IEC 81714-3 Part 3: Classification of connect nodes, networks and their encoding.
IEC 61286 Information technology - Coded graphic character set for use in the preparation of documents used in electrotechnology and for information interchange, specifies a character set for use in electrotechnical diagrams. The character set contains qualifying symbols to graphical symbols.
IEC/TR 61352 Mnemonics and symbols for integrated circuits, and IEC/TR 61734 Application of symbols for binary logic and analogue elements, are technical reports that support the use of IEC 60617.
