1 International Electrotechnical CommissionIEC 60617 - graphical symbols for diagrams > > > > > >(requires password)Welcome to the IEC 60617 databaseIEC 60617 contains graphical symbols for use in electrotechnical diagrams . All the parts (Ed. 2 or3) of the previously published IEC 60617 have been incorporated into this database that currentlyincludes some 1900 symbols . The database is the official source of IEC and End-User RestrictionsAccess to the database is on a subscription basis. Subscriptions can be purchased through the IECN ational Committees, National Committee-appointed Sales Outlets, or directly from the IECW ebstore (simply search for IEC 60617 ). All subscriptions are subject to the customer agreeing tothe IEC Webstore Product(s) Licence versionsIn addition to the normative database maintained by TC 3, IEC also hosts localized versions of IEC60617 maintained under the responsibility of the respective National Committees.

2 The followinglocalized versions are currently available:FinnishJapaneseDanishScopeThe following areas are covered in the database:Conductors and connecting devicesBasic passive componentsSemiconductors and electron tubesProduction and conversion of electrical energySwitchgear, controlgear and protective devicesMeasuring instruments, lamps and signalling devicesTelecommunications transmission, switching and peripheral equipmentArchitectural and topographical installation plans and diagramsBinary logic elementsAnalogue and hybrid elementsNew metadata and search capabilityThe incorporation of the symbols into the database has been accompanied by the addition of aconsiderable amount of new metadata not present in the previous publication (symbol name,alternative names, keywords, remarks, etc.)

3 And links to related symbols and application notes. Thedatabase also provides classified views (by shape, function and application) and a search facility. Itis therefore a much richer and more user friendly tool for those who need to understand and applygraphical symbols in electrotechnical database is maintained by a validation team appointed by the IEC National Members. Requestsfor modifications and new symbols are processed via change requests addressed to the validationteam by IEC National Committees and CommitteesNational Committees should send a list of staff members who are to be authorized to access thedatabase. The list should include the name and username for each person (username is thatcurrently used to access working documents on the IEC web site).

6 Thelocalized versions are hosted by IEC but are prepared and maintained under the soleresponsibility of the respective National Committees. The following localized version iscurrently available:JapaneseFinnishDanishLinksAll items in blue, including the arrow triangles in the categorized views, represent links toother elements or to specific action. Finding a symbolThe IEC 60617 database provides two methods for finding a symbol:1. Search functionThe query is processed in the language specified. You can use an asterisk (*) as awildcard and combine two search terms with a boolean "AND" or "OR" operator. Thefollowing fields are used in constructing the query: Name, Alternative names,Keywords, Earlier published in ( 03-01-15) and Symbol identity number ( ).

7 2. Categorized viewsSymbols are categorized by symbol identity number, keyword, application class,function class, shape class, status level and earlier publication. After selecting a viewclick on the blue arrow to expand the list. Clicking on an item reference (in blue) bringsup the detail page. Within the detail page there may be further links to relatedsymbols, application notes, IEC Central Office produces periodically a snapshot of the database contents in PDFformat.

9 It defines an international "pictoriallanguage" used in electrotechnical diagrams . In a way similar to how words can be combinedto form more complex expressions and meanings, the pictorial representations of thisstandard can be combined to build more expressive or specialised concept " graphical symbol" is normally defined as a visually perceptible figure used totransmit information independently of the purposes of the IEC 60617 the notion of a graphical symbol is somewhat broader toencompass objects that contain information on concepts including their associated graphicalrepresentations. Each object has an identifier (symbol identity number), a name, a statuslevel, a graphical representation and a set of optional attributes.

10 These are described asfollows: Symbol identitynumberan identifier of the form "Snnnnn" where n is an integer from 0 to9. The numbers are sequential but carry no semantic short description of the meaning of the symbolAlternative namessynonymous, "almost synonymous" and possibly branch specificnames, etc. under which the symbol might also be knownStatus levelthe status of the symbol in relation to the standardizationworkflow. When a symbol is approved, its status is set to"Standard". If the symbol is later replaced by another, or if it isdeemed technically obsolete, its status becomes "Obsolete - forinformation only". In the case of technical obsolescence thesymbol may still be used, although it is no longer maintained. (Other status levels are applied during the standardizationprocedure, such as "Proposed", "Draft" and "Rejected")Released onthe date at which the symbol was released as Standard in thedatabase for public useObsolete fromthe date at which the status level of the symbol was set to"Obsolete - for information only"Replacesthe identity number of the symbol replaced by the present oneReplaced bythe identity number of the symbol replacing the present oneApplication noteslinks to common descriptive notes with additional relevantinformation, normally shared among several symbolsThe former Part 12 and 13 of IEC 60617 contained someextensive general textual sections.
