Abstract

1.1 This test method covers the determination of the overall kinetic parameters for exothermic reactions using theFlynn/Wall/Ozawa method and differential scanning calorimetry.1.2 This technique is applicable to reactions whose behavior can be described by the Arrhenius equation and the general ratelaw.1.3 Limitations—There are cases where this technique is not applicable. Limitations may be indicated by curves departing froma straight line (see 11.2) or the isothermal aging test not closely agreeing with the results predicted by the calculated kinetic values.In particular, this test method is not applicable to reactions that are partially inhibited. The technique may not work with reactionsthat include simultaneous or consecutive reaction steps. This test method may not apply to materials that undergo phase transitionsif the reaction rate is significant at the transition temperature.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 This standard may involve hazardous materials, operations, and equipment. This standard does not purport to address allof the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriatesafety safety, health, and healthenvironmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles onstandardizationestablished in the Decision on Principles for the Development of International Standards, Guides and Recommendations issuedby the World Trade Organization Technical Barriers to Trade (TBT) Committee.
