Abstract
Preliminary results are reported on the non-uniqueness of the ITS-90 using high temperature SPRTs (HTSPRTs) in the range 660 C to 962 C. To achieve temperature stability and uniformity of the test HTSPRTs, the method employs the thermal isolation of the Inconel metal comparison block inside a sealed potassium heat pipe controlled to 0.01 C. Eleven HTSPRTs of three designs from five manufacturers were tested. In addition to measurements near the calibration temperatures 663.3 C and 966.6 C to test the temperature uniformity of the comparison block, measurements were made at 703.3 C, 724.4 C, 753.2 C, 801.7 C, 847.5 C, and 913.7 C.Proceedings Title
