A model consisting of a mixture of functions representing the heat capacity of the glassy and non-glassy fractions, the glass transition progress and the enthalpic relaxation is proposed to explain standard DSC curves in the glass transition region. Optimal fittings of the model allowed to estimate the reversing and non-reversing signals from standard DSC data. The estimates resulted to be similar to the signals obtained by MTDSC, but with the advantage of being not affected by the modulation frequency.
