DSC has been widely used for thermal analysis of various materials. But the methods of measurements and the reliability of the obtained data have been discussed very little. So we tried to investigate these problems from the point of view of temperature distribution in the sample and thermal balance of the sample. It was proved that the temperature distribution in the sample must be taken into consideration, even if the quantity of the sample used is small. Read out temperature diverges from the true temperature linearly with scanning rate. It is necessary to obtain the corrected base line for the measurements of heat of fusion of the materials of large temperature range of melting.
