The TG-NCTh-HTPFU has been addressed the following tasks on behalf of the WG-NCTh:

  • Construct comprehensive list of uncertainty components for determining T of HTFPs and their use as thermodynamic temperature references (or artifacts);

  • Categorize the items in the list as either well specified or as requiring further investigation;

  • Report back to CCT WG NCTh with a list and recommendations for next steps.
