Abstract
We analyze two important points related to the experimental emissivity measurements in this paper: the radiometer calibration accuracy and its stability to determine the required frequency of calibration. The usual two-temperature calibration method is compared to a more accurate method, which uses the measurement of blackbody radiation at several temperatures. Additionally, the suitability of the two- temperature method is studied as a function of the gap between both temperatures. Differences higher than
