Standard Test Methods for Kinetic Parameters by Differential Scanning Calorimetry Using Isothermal Methods

Importancia y uso:

6.1 These test methods are useful for research and development, quality assurance, regulatory compliance, and specification acceptance purposes.

6.2 The determination of the order of a chemical reaction or transformation at specific temperatures or time conditions is beyond the scope of these test methods.

6.3 The activation energy results obtained by these test methods may be compared with those obtained from Test Method E698 for nth order and accelerating reactions. Activation energy, pre-exponential factor, and reaction order results by these test methods may be compared to those for Test Method E2041 for nth order reactions.
