The practical applicability and the relevance of a classification of processes into three different regimes is examined based on some typical TMDSC experiments. It is demonstrated that this classification, simply based on the presence and temperature susceptibility of an excess process, is very useful to identify and understand phenomena observed with TMDSC. The ability to separate the base-line heat capacity from excess phenomena is undoubtedly the most valuable feature of TMDSC. Nonetheless, one has to realize that this feature is restricted to excess processes that are not susceptible to the temperature modulation such as for instance curing and enthalpy recovery. Crystallization and melting processes, on the other hand, are susceptible to the temperature modulation and thus the complex heat capacity is in that case not uniquely determined by the base-line heat capacity. In addition, the strong temperature dependence of the kinetics in combination with the generally large heat flow, imply that the conditions applied are very critical to obtain a reliable complex heat capacity. In spite of these serious limitations it is demonstrated that TMDSC can provide additional insight in the crystallization and melting behaviour using (step-wise) quasi-isothermal measurements (i.e. beta(0)=0)
