The first setup consists of several heat-pipe blackbodies in conjunction with platinum resistance thermometers, calibrated according to the International Temperature Scale of 1990 (ITS-90) and is applied for calibrations in the temperature range from-60 C to 961.78 C. In the temperature range from 962 C to 3000 C the calibration is based on high temperature blackbodies. The temperature of these blackbodies is determined in two independent ways: traceable to the ITS-90 gold fixed point or via absolutely calibrated filter radiometers (FR) traceable to the detector primary standard, the cryogenic radiometer. Taking advantage from the high accuracy of the FR calibration, these FRs have also been successfully used for the investigation of the thermodynamic accuracy of the ITS-90 in the range from 419 C to 962 C. For non-contact temperature measurements, the emissivity of the observed object is one of the most important parameters. Therefore, PTB has set up instrumentations for measuring the directional spectral and total emissivity of samples in air from 80 C up to 400 C over a spectral range from 4 µm to 40 µm and under vacuum from 0 C to 600 C and in the spectral range from 1 µm to 1000 µm.}, language = {en} } @article{HartmannAnhaltHollandtetal., author = {Hartmann, J{\"u}rgen and Anhalt, Klaus and Hollandt, J{\"o}rg and
