CCT Working Group for Non-Contact Thermometry (CCT-WG-NCTh)

Termes de référence

The terms of reference of WG-NCTh are to study and advise the CCT on issues related to thermal radiation and other non-contact methods for temperature measurement.

Tasks:

• Reviewing and reporting on measurements of T – T₉₀ and fixed points by primary non-contact thermometry;
• Reviewing the research and application of non-contact primary thermometers to realise the kelvin;
• Coordinate activities related to high-temperature fixed points;
• Provide appropriate input into the mise en pratique for the definition of the kelvin;
• Provide, where required, input into the guides on thermometry;
• Provide definitive guidance, when required, on the use of secondary non-contact thermometry methods (e.g. phosphor, gold-cup thermometry);
• Support world-wide efforts in standardization of radiation thermometer and thermal imager testing and calibrations;
• Develop appropriate uncertainty budgets for radiation thermometry;
• Recommend key comparisons relevant to WG-NCTh to the CCT;
• Develop, when required, guidance for measurement best practices in novel non-contact thermometry techniques (e.g. plasma and flame thermometry).
