Terms of reference

The terms of reference of the CCT-WG-NCTh are to study and provide definitive advice to the CCT on issues related to thermal radiation and other approaches underlying non-contact temperature measurements.

WG-NCTh is tasked with:

  • Review and report on measurements of T- T90 and associated fixed points by means of primary non-contact thermometry;
  • Review research and application of non-contact thermometry primary thermometers to realise the kelvin;
  • Review and advise CCT on research related to high-temperature fixed points;
  • Provide appropriate input, including revisions, into the mise en pratique for the definition of the kelvin;
  • Provide, where required, updates for a) the supplementary information and b) approximating techniques as regards the ITS-90;
  • Support world-wide efforts in standardization of radiation thermometer and thermal imager testing and calibration;
  • Develop appropriate uncertainty budgets for radiation thermometry;
  • Recommend key comparisons relevant to WG-NCTh and to the CCT;
  • Develop, when required, guidance for measurement best practice for secondary/novel non-contact thermometry techniques (e.g. phosphor, gold-cup thermometry, flame and plasma thermometry);
  • Provide definitive guidance on the practice of Body Temperature Measurement (TG BTM).
