The change at the beginning of the test is hesitant to the initial "start offset (1). In this transient region, the state suddenly changes from the constant temperature mode to the linear temperature rise mode. After the offset is started, the temperature is raised at the programmed rate. The size of the shift depends on the heat capacity and heating rate of the sample. In the glass transition zone (2), the heat capacity of the sample increases, and an endothermic step can be observed. The cold crystallization process (3) forms an exothermic peak and peak area. It is equal to the crystal enthalpy. The melting of the crystallite forms an endothermic peak (4). If a volatile substance such as a solvent is present in the sample, an endothermic peak due to evaporation (5) can be observed. Finally, decomposition starts at a higher temperature ( 6).
