Contains graphical symbols for analogue elements in fields such as computation and control, to be used in diagrams. The symbols and descriptions have been prepared with a view to electrical applications, but may also applied to non-electrical systems (e.g. pneumatic, hydraulic or mechanical). This standard is not necessarily applicable to programming applications using general purpose analogue computers equipped with a removable path (programming) panel. It includes in detail: qualifying symbols for signal identification and amplifiers, symbols for amplifiers, function generators, coordinate converters, signal converters, electronic switches, and coefficient scaler.
