Abstract: A list of graphic symbols and class designation letters for use on electrical and electronics diagrams is provided. All of the symbols are designed so that their connection points fall on a modular grid, to help those who use a grid basis for the preparation of diagrams.

[IEEE Std 315-1975]) This American National Standard is a revision and expansion of American National Standard Graphic Symbols for Electrical and Electronics Diagrams, Y32.2-1970 (IEEE Std 315-1971). A variety of specialized symbols originally used for aircraft applications have been added to make this standard more comprehensive.

A list of graphic symbols and class designation letters for use on electrical and electronics diagrams is provided. All of the symbols are designed so that their connection points fall on a modular grid, to help those who use a grid basis for the preparation of diagrams.
