ASTM E698-05 PDF

Description

1.1 This method covers the determination of the overall kinetic parameters for exothermic reactions using the Flynn/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 rate law.

1.3 LimitationsThere are cases where this technique is not applicable. Limitations may be indicated by curves departing from a straight line (see ) or the isothermal aging test not closely agreeing with the results predicted by the calculated kinetic values. In particular, this method is not applicable to reactions that are partially inhibited. The technique may not work with reactions that include simultaneous or consecutive reaction steps. This method may not apply to materials that undergo phase transitions if the reaction rate is significant at the transition temperature.

1.4 SI units are the standard.

This standard may involve hazardous materials, operations, and equipment. 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.
