ASTM-E3007 › Standard Practice for Selection and Use of Kinetic Reference Values in the Study of Decomposition Reactions by Thermogravimetry
The following bibliographic material is provided to assist you with your purchasing decision:
Scope
1.1 It is the purpose of this practice to provide kinetic parameters for reference material(s) to be used for evaluation of thermogravimetry methods, apparatus, and software where decomposition mass loss and associated temperature are measured. This practice addresses nth order reactions.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This 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.
Significance and Use
5.1 The kinetic parameters provided in this practice may be used to evaluate the performance of a standard, apparatus, technique or software for the determined mean parameters (such as Test Methods E1641 and E2958). The results obtained by these approaches may be compared to the values provided by this practice.
