International practical temperature scale

MAY 01, 1963

A revision of the international practical scale of temperatures is in the making, and some steps being taken in that direction are discussed in this account of the most recent meeting of the Advisory Committee on Thermometry of the International Committee on Weights and Measures. The author is dean of the College of Chemistry and Physics at Pennsylvania State University.

On September 25–27, 1962, the Advisory Committee on Thermometry of the International Committee on Weights and Measures met under the presidency of Professor J. de Boer of Amsterdam, in Sèvres (a suburb of Paris), in the Pavilion de Breteuil, the home of the International Bureau of Weights and Measures, and for three days discussed important matters relating to international standards of thermometry. The Advisory Committee on Thermometry is one of the working groups of the International Committee on Weights and Measures, a committee established in 1875 by the “Convention du Mètre”, an international treaty between the principal industrial and scientific nations for obtaining international agreement on physical standards of measurement for science, technology, and industry.
