Abstract :
Preparation of a new dictionary of letter symbols and abbreviations to be used by engineers and scientists is a task to be undertaken by a committee of the American Standards Association. The committee on symbols and abbreviations which has been at work for many years and which has already published several standards, has recently been divided into 2 parts, one covering the letter symbols and abbreviations, and the second covering the graphical symbols. The committee working on letter symbols and abbreviations, which is now beginning its work, has 12 subcommittees covering such broad subjects as mathematics, physics and mechanics, structural analysis, hydraulics, heat and thermodynamics, photometry and illumination, aeronautics, electric and magnetic quantities, radio, astronomy and surveying, geodesy, and scientific and engineering terms.
