Abstract

There is not, as yet, an international agreement on procedures for the temperature calibration and caloric calibration of DSCs which have been definitely backed up both theoretically and experimentally. The results of investigations in this respect will have to be taken into account in the relevant calibration regulations, and they also show the basic limits set to the reliability of measurements. To what extent DSCs are capable of being calibrated depends on the quality of the DSCs’ measuring system, on operational parameters and on the availability of precisely measured calibration materials. Here, the situation is still quite unsatisfactory. Moreover, no complete theory of the DSCs exists, which takes full account of the systematic influences from the instrument and inherent error sources. It should be borne in mind that it is the overall uncertainty of the calibration which yields the smallest possible systematic uncertainty of the measurements.
