Organization: ASTM
Publication Date: 10 May 1999
Status: inactive
Page Count: 7
ICS Code (Environmental testing): 19.040
scope:

This method covers the determination of the overall kinetic parameters for exothermic reactions.

The kinetic parameters are obtained from differential scanning calorimetry (DSC) curves (see Section 3).

This technique is applicable to reactions whose behavior can be described by the Arrhenius equation and the general rate law.

Limitations - There are cases where this technique is not applicable. Limitations may be indicated by curves departing from a straight line (see 10.2) or the isothermal aging test not closely agreeing with the results predicted by the calculated kinetic values. In particular, this method is not applicable 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 the transition temperature.

This standard may involve hazardous materials, operations, and equipment. This standard does not purport address all of the safety problems associated with its use. It the responsibility of whoever uses this standard to consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
