The calibrations of a platinum and a germanium resistance thermometer were carried out above 14K and between 5 and 15K, respectively. The platinum scale was calibrated against the triple, boiling, and sublimation points of n-H2, Ne, N2, O2, and CO2 and also their vapor pressure scales. The comparison with IPTS-68 suggests that the platinum scale has shown a deviation of +2-3mK in 8 years' time below 90K. The germanium scale was fixed by 4He gas thermometry. The heat capacity measurement of solid HI as an example shows that the calibrations were successfully carried out. Some remarks on such calibrations are also described.
