| Abstract: | One of the significant uncertainties in Standard Platinum Resistance Thermometer (SPRT) calibration by fixed-points method is Type I non-uniqueness (sub-range inconsistencies). Sub-ranges water-tin (W 9 ) and water-indium (W 10 ) lies in the water-zinc (W 8 ) sub-range of the International Temperature Scale of 1990. Therefore, three sub-range inconsistencies W 8 and W 9 (SRI 8–9 ), W 8 and W 10 (SRI 8–10 ), and W 9 and W 10 (SRI 9–10 )] occur. This paper investigated these inconsistencies using the calibration data of 12 SPRTs from six manufacturers. The result shows that the magnitude of the inconsistency for SRI 8–9 , SRI 8–10 , and SRI 9–10 are about 2.5, 2.2 and 1.8 mK, respectively. |
