In July 2016 the Consultative Committee for Thermometry’s Non-Contact Thermometry Working Group formed a task group to compile a complete list of uncertainties for high-temperature fixed points, categorize them as well specified or not, and recommend areas of future research. We describe herein two paths to realizing T by indirect primary radiometry using high-temperature fixed-point blackbody cells: one in which published values for the metal–carbon eutectic material transition temperatures are used and the other where a set of cells has their transition temperatures determined directly. The uncertainty components that need to be considered for each path are given together with typically achievable values and how well those values are known. This work concentrates on Co–C, Pt–C and Re–C.

2016 年 7 月，测温咨询委员会非接触式测温工作组成立了一个任务组，负责编制一份完整的高温定点不确定性清单，将它们分类为明确与否，并推荐未来的研究领域。我们在此描述了使用高温定点黑体电池通过间接初级辐射测量实现T的两种途径：一种是使用已公布的金属-碳共晶材料转变温度值，另一种是一组电池具有其转变温度直接确定。需要为每条路径考虑的不确定性分量与通常可实现的值以及这些值的已知程度一起给出。这项工作集中在 Co-C、Pt-C 和 Re-C 上。
