Significance and Use | ||||||||||||||||||||||||
6.1 This test method is useful for research and development, quality assurance, regulatory compliance and specification-based acceptance. 6.2 The kinetic parameters determined by this method may be used to calculate thermal hazard figures-of-merit according to Practice E1231. |

1. Scope | ||||||||||||||||||||||||
1.1 This test method describes the determination of the kinetic parameters of Arrhenius activation energy and pre-exponential factor using the Kissinger variable heating rate iso-conversion method (1, 2)2 and activation energy and reaction order by the Farjas method 1.2 Both nth order and accelerating reactions are addressed by this method over the range of 0.5 < n < 4 and 1 < 1.3 This test method uses the same experimental conditions as Test Method E698. The Flynn/Wall/Ozawa data treatment of Test Method E698 may be simultaneously applied to these experimental results. 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 There is no ISO equivalent to this standard. 1.6 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. |
