Abstract : The reproducibility of the IPTS-68 as determined by forty-eight thermometers is shown to be within approximately plus or minus 3mK in the range 13.81 K to 20.28 K, plus or minus 1 mK in the range 2.28 K to 54.361 K, and plus or minus 2 mK in the range 54.361 K to 90.188 K. In the range 90.188 K to 273.15 K, nine thermometers exhibit a scale reproducibility within only plus or minus 5 mK; it is believed that this figure is limited by calibration uncertainties, and that plus or minus 1 mK is more likely to be typical.
