Reference values for temperature, pressure, and humidity

H. W. Tenney (Westinghouse Electric and Manufacturing Company, East Pittsburgh, Pa.): Messrs. Bellaschi and McAuley have rendered a very valuable service in tabulating the reference values for temperature, pressure, and humidity generally used in the various branches of electrical engineering. With these data presented so concisely, direct comparisons of the reference values used by national and international bodies become possible. The very important problem of co-ordination, particularly of such fundamentals as reference values, is receiving more and more attention from our engineering societies and standardizing bodies.
