Standards For Symbols
There are several national and international standards for graphical symbols in circuit diagrams, in particular:
- IEC 60617 (also known as British Standard BS 3939)
- ANSI standard Y32 (also known as IEEE Std 315)
- Australian Standard AS 1102
Different symbols may be used depending on the discipline using the drawing. For example, lighting and power symbols used as part of architectural drawings may be different from symbols for devices used in electronics. National and local variations to international standards also exist.

Famous quotes containing the words standards and/or symbols:
“The things a man has to have are hope and confidence in himself against odds, and sometimes he needs somebody, his pal or his mother or his wife or God, to give him that confidence. Hes got to have some inner standards worth fighting for or there wont be any way to bring him into conflict. And he must be ready to choose death before dishonor without making too much song and dance about it. Thats all there is to it.”
—Clark Gable (19011960)
“I do not deny that there may be other well-founded causes for the hatred which various classes feel toward politicians, but the main one seems to me that politicians are symbols of the fact that every class must take every other class into account.”
—José Ortega Y Gasset (18831955)
