3.1 Phase correction
The previous calculation scheme may lead to erroneous results, as the basic equation (1) and the previous scheme assume a zero phase shift between the thermal response and the modulated excitation signal q (t ) in the absence of kinetic phenomena. This assumption is not entirely accurate: the phase shift between the two experimental signals is due to the time required for heat exchange between the DSC cell and the sample itself (non-exhaustively, this includes the geometry and symmetry of the cell, the cup/support pair, the cup/sample pair) (figure...

Standards and norms
The international standard ISO (International Standardization Organization) is recommended but not mandatory.
The European standard (EN) is mandatory. It replaces the equivalent national standard.
The French standard (NF) applies in the absence of other European or international standards.
