Title: The Roles of the Mise en Pratique for the Definition of the Kelvin
Published: October 16, 2010
Abstract: The mise en pratique (,practical realizationŠ) for the definition of the kelvin (MeP-K) was created by the Consultative Committee for Thermometry (CCT) in 2006 to give practitioners of thermometry a guide to the realization of the kelvin, in accord with the International System of Units. The International Committee for Weights and Measures also foresaw that adoption of the proposed new definition of the kelvin, based on a fixed value for the Boltzmann constant, would require an MeP-K. The MeP-K recognizes realizations by primary methods, formal temperature scales, and indirect approximations. By providing a framework for primary methods and indirect methods, the MeP-K will foster development and application of new methods, such as the use of absolute radiometry or high-temperature fixed points. The MeP-K provides the CCT with a mechanism to update and expand the thermometric methods in common use, without imposing on industry the high costs of changing the International Temperature Scale.
