- Abstract
Key comparisons (KCs) are required to ensure equivalence between laboratories and to substantiate Calibration and Measurement Capabilities (CMCs). The previous radiation thermometry KC (CCT-K5) finished in 1999 and used tungsten ribbon lamps as the transfer instruments. These were not ideal: - their radiance temperature is strongly wavelength dependent, so corrections - had to be applied to the results to account for the different measurement wavelengths - the target size of lamps is small (typically 1.5 mm width) compared to the field-of-view of many radiation thermometers - the inherent uncertainties associated with lamps tend to be large - the upper temperature of the comparison was 1700 °C whereas many laboratories can now achieve up to 2500 °C or even 3000 °C., XIII International Symposium on Temperature and Thermal Measurements in Industry and Science, TEMPMEKO 2016, June 26 - July 1, 2016, Zakopane, Poland
