1.1 These test methods describe the model-free determination of Arrhenius activation energy by thermogravimetry using the factor jump (1)2 (Test Method A) or modulated thermogravimetry (2) (Test Methods B and C) techniques. With the assumption of a first-order kinetic model, the pre-exponential factor is additionally determined.
