Abstract
The definition and realization of a new temperature scale, The 1976 Provisional 0.5K to 30K Temperature Scale (EPT-76), are reviewed. The scale is intended to correct deviations of the IPTS-68 from the thermodynamic scale below 30K and to set an international temperature scale down to 0.5K. The realization of superconductive transition points as reference temperatures, the interpolation by gas thermometer and magnetic one, and the calibration of a germanium thermometer and a Rh-0.5% Fe alloy thermometer are illustrated.
