Bilateral Comparison of Radiation Temperature Measurements from-20 to 1600 degrees C Between TUBITAK-UME (Turkey) and SASO-NMCC (Kingdom of Saudi Arabia)

We report the results of a bilateral comparison of radiation temperature measurements between SASO-NMCC (National Measurement and Calibration Center of Kingdom of Saudi Arabia) and TUBITAK-UME (National Metrology Institute of Turkey) over the range of the nominal target temperature from - 20 to 1600 degrees C. Two radiation thermometers, employed as the transfer standard instruments, were provided by the pilot laboratory TUBITAK-UME and traceable to the UME primary level radiation temperature scale approximation and realization. During the measurements each laboratory applied its own internal calibration procedures. The results of the comparison showed that all twelve pairs of temperature measurements performed by the participating laboratories are in a good agreement within declared combined standard uncertainty values. The comparison results obtained here support calibration and measurement capabilities both of UME and SASO.
