GB/T 24340-2009Graphical symbols for use on electrical diagram of industrial machines (English PDF)

GB/T 24340-2009 is the English-translated version of 工业机械电气图用图形符号.

GB/T 24340-2009 is the collection of graphical symbols used on the electrical diagrams of industrial machines.

The summary on the page states that the standard specifies the graphical symbols used in the electrical diagrams of industrial machinery and that it applies to the electrical drawings and other technical documents of industrial machinery, including machine tools, casting machinery, textile machinery, lifting machinery, construction machinery, sewing machines and plastics machinery; the body of clause 1 is not reproduced on the page.

The table of contents shows sixteen clauses, and the symbol collections run from symbol elements, qualifying symbols and other commonly used symbols, through wires and connecting devices, passive components, semiconductor, photosensitive, magnetic and digital display symbols, the conversion of electrical energy, switches, control and protection devices, measuring instruments, lamps and signalling devices, solenoid valves, electromagnetic clutches, electromagnetic suckers and electromagnetic speed control devices, to binary logic units, analogue units and the graphical symbols of data processing systems.

The titles of two entries in that table of contents, clauses 4 and 12, are garbled in the draft and so are not repeated here.

Clause 3, Terms and definitions, prints two definitions without their term names: a device or concept that conveys information intuitively in graphical, or pictorial, and/or character form without the use of language and that can be drawn, printed or produced by other means; and a part of a graphic symbol, with a note that the symbol of a tube is built from symbol elements such as filament, gate, anode and shell.

Clause 2 cites the parts of GB/T 4728 listed on the page, which run from GB/T 4728.1-2005 to GB/T 4728.13-2008. The page gives the word count estimate of the standard as 73,718. It was issued on 30 September 2009 and has applied since 1 February 2010.
