The terms of reference of TG-SI follow closely CIPM Recommendation 1 of 2005 (CI-2005), "Preparative steps towards new definitions of the kilogram, the ampere, the kelvin and the mole in terms of fundamental constants", and are repeated here for convenience:
consider the implications of changing the definitions of the above-mentioned base units of the SI, with particular emphasis on the kelvin, from the point of view of metrology in thermometry;
present this point of view to the CCT and to other concerned Consultative Committees or their appropriate Working Groups and to work with them to prepare a report to the CIPM not later than June 2007;
monitor closely the results of new experiments relevant to the possible new definition of the kelvin, and to identify necessary conditions to be met before proceeding with changing the definition;
solicit input from the wider scientific and technical community on this important matter.
CCT summary
consider the implications of changing the definitions of the above-mentioned base units of the SI, with particular emphasis on the kelvin, from the point of view of metrology in thermometry;
