ASTM E2890-12 (R2018) pdf free download.Standard Test Method for Kinetic Parameters for Thermally Unstable Materials by Differential Scanning Calorimetry Using the Kissinger Method.
1.1This test method describes the determination of the kinetic parameters of Arrhenius activation energy and preexponential factor using the Kissinger variable heating rate iso-conversion method (1, 2)2 and activation energy and reaction order by the Farjas method (3) for thermally unstable materials. The test method is applicable to the temperature range 1mm 300 to 900 K (27 to 627°C).
1.2 Both nth order and accelerating reactions are addressed by this method over the range of 0.5
