CCT Task Group for Guides on Thermometry (CCT-TG-GoTh)

Terms of reference

To promote good thermometry practice and traceability to the SI by preparing and publishing guides on thermometry, with a focus on secondary thermometry. The guides should include techniques, thermometers, instrumentation, and uncertainty analyses for traceable temperature measurements.


    Revise and replace the BIPM publication Techniques for Approximating the ITS-90 (the bluebook).

    Create a database on temperatures and uncertainties for secondary fixed points.
