CCT Working Group for Contact Thermometry (CCT-WG-CTh)

Terms of reference

The terms of reference of WG-CTh are to review and document progress in contact thermometry, with a focus on thermodynamic temperature determination and defined scales. The list of tasks has been updated according to the discussions at the WG-SP meeting on 31 May 2017 and is given below.

Tasks:

• reviewing and reporting on measurements of T – T₉₀ and T – T₂₀₀₀;
• recommending key comparisons in contact thermometry to the CCT;
• reviewing the research and application of primary contact thermometers to realize the kelvin;
• updating the Mise en Pratique of the definition of the kelvin;
• updating the Guide to the Realization of the ITS-90;
• reviewing novel contact thermometry techniques.
