| Zusammenfassung | The Terms of Reference 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 the convenience of the reader: • 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. |
