| Abstract: | According to the JJF 1059|1999, an uncertainty evaluation method for the calibration of secondary standard platinum resistance thermometers by using zinc freezing points and water boiling point is introduced. The components of standard uncertainty are determined by using the mathematical model of measurement. The expanded uncertainties and the coverage factors are presented at each temperature between the two fixed points. |
