Over deze norm
1.1 These test methods describe the model-free determination of Arrhenius activation energy by thermogravimetry using the factor jump (1)2 (Method A) or modulated thermogravimetry (2) (Method B) techniques. With the assumption of a first-order kinetic model, the pre-exponential factor is additionally determined.
1.2 These test methods are applicable to materials with well-defined decomposition profiles, namely, a smooth, continuous mass change.
1.3 These test methods are applicable to decomposition occurring in the range from 400 K to 1200 K (nominally 100°C to 900°C). The temperature range may be extended depending on the instrumentation and material used.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 There is no ISO standard similar to this standard.
1.6 This 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 and health practices and determine the applicability of regulatory limitations prior to use.
