| Abstract: |
The National Institute of Standards and Technology (NIST) is in charge of realizing, maintaining, and disseminating the international Scale of 1990 (ITS-90). The Standard Platinum Resistance Thermometer (SPRT) Calibration Laboratory of the NIST Thermometry Group realizes the ITS-90 from the argon triple point (Ar TP, 189.3442 °C) to the silver freezing point (Ag FP, 961.78 °C) for the calibration of SPRTs. This special publication describes the calibration services, methods, measurement assurance, and uncertainties for the NIST ITS-90 calibration SPRTs. |
