This test method describes the determination of the kinetic parameters, Arrhenius activation energy, and preexponential factor by thermogravimetry, based on the assumption that the decomposition obeys firstorder kinetics using the Ozawa/Flynn/Wall isoconversional method(1,2).2
1.1This test method describes the determination of the kinetic parameters, Arrhenius activation energy, and preexponential factor by thermogravimetry, based on the assumption that the decomposition obeys firstorder kinetics using the Ozawa/Flynn/Wall isoconversional method (1, 2).2
1.2This test method is generally applicable to materials with welldefined decomposition profiles, namely, a smooth, continuous mass change with a single maximum rate.
1.3This test method is normally applicable to decomposition occurring in the range from 400 K to 1300 K (nominally 100°C to 1000°C). The temperature range may be extended depending on the instrumentation used.
1.4The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.6This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
