Standard graphic symbols

Symbols have been in vogue since the early ages and are particularly useful to the electrical engineer. Those now in use are the result of growth and evolution and there is no uniformity or agreement. It is desirable to standardize them as far as possible in order to afford simplicity and general usefulness, but it is suggested that the Institute undertake for the present to standardize only those symbols which would be most general and widely used. The general principles which should govern selection are discussed, and there is given a list of suggested symbols covering some of the most important items. These are offered for criticism and suggestions in order to assist toward definite standardization.
