Standard Test Methods for Kinetic Parameters by Factor Jump/Modulated Thermogravimetry

Importancia y uso:

5.1 The activation energy may be used to calculate thermal endurance and an estimate of the lifetime of the material at specified temperatures using Test Method E1877.

5.2 The kinetic parameters determined by these test methods may be used in quality assurance, specification acceptance, research, and development.

5.3 The kinetic parameters of activation energy and logarithm of the pre-exponential factor determined by these test methods have little intrinsic value in themselves. Most practical applications of this information, such as lifetime estimation (see Test Method E1877), also require an estimation of the precision of the respective values. Determination of that precision by replicated determination is a non-manditory part of these test methods.
