Graphical symbols for diagrams — Part 2: Graphical symbols

This International standard specifies graphical symbols for diagrams for general application. The standard constitutes a symbol library, from which users can use the symbols or created symbol examples for use in diagrams. Graphical symbols for fluid power objects are covered by ISO 1219-1 Graphical symbols for electro technical objects are covered by IEC 60617 DB.
