The approximations to the International Temperature Scale of 1990 described here provide levels of accuracy that are adequate for the great majority of thermometric requirements, and in general do so with greater convenience or at lower cost than would be the case in realizing the ITS-90 itself. Thermometrists who do require the accuracy only available from, or the imprimatur of, the ITS-90 are referred to the text of that scale and, more particularly, to the comparison monograph to this one: Supplementary Information for the ITS-90.
