Usually the thermally stimulated current (TSC) is a result of measurement for rising temperature at constant rate. To give an explanation of this result, two TSC equations are assumed. If TSC is measured at stepped increasing temperature, there is no need of any equation to use as assumption. The experimental results of two methods for polypropylene are compared. It shows that the usual TSC equations are not correct for TSC measurement; although these equatons are correct in thermal equilibrium state of crystal, but they can not be used for polymer particularly in non-equilibrium state.
