Measurement of environmental warmth in SI units

Abstract

Ellis, F. P., Smith, F. E., and Walters, J. D. (1972).Brit. J. industr. Med.,29, 361-377. Measurement of environmental warmth in SI units. Although `Environmental Warmth and Its Measurement' (Medical Research Council War Memorandum No. 17), written over 25 years ago for the Royal Navy, is still widely used and has not been revised, the validation and amplification of the methods proposed by the late Dr. Thomas Bedford have in the meantime been in hand continuously in the laboratory and in the Fleet under the auspices of the Council's Royal Naval Personnel Research Committee. While it was not considered appropriate by Council to replace or to rewrite the Memorandum at the present time, in view of the recent adoption of the metric system and the units of the International System (SI Units) it was thought that it would be helpful to publish metricated charts corresponding to those which appear in the Supplement to War Memorandum No. 17, together with two additional charts which are the result of work in the post-war years, to provide investigators with simple aids for use in the laboratory or the field and to provide a basis for considering the requirements for further research.
