Determination of q f T from Isothermal Experiments

This should either deliver a flat thermogram, or show the residual energy due to an autocatalytic reaction step. This practice ensures that the maximum heat release rate measured is correct. 

Common to these methods, is that only one point, that is, the maximum heat release rate of the thermogram, is used. Even if the method by itself is efficient in terms of simplicity, experimental work, and evaluation time, it represents a waste of information, in the sense that all the available information is not used in the procedure. Nevertheless, from the point of view of safety it is conservative, since it is based on the zero-order approximation. More complex methods are based on a kinetic analysis of the thermograms presented in Section 11.4.3 below. 

From one reference point and knowing the activation energy, the heat release rate can be calculated for different temperatures  

The heat release rate qm can, in turn, be used to calculate the time to maximum rate (TMRld) at the temperature T  

This equation calculates the TMRld as a function of temperature.
