ASTM E2781-11

The kinetic parameters provided in this standard may be used to evaluate the performance of a standard, apparatus, techniques or software for the determination parameters (such as Test Methods E698, E1641, E2041, or E2070) using thermal analysis techniques such as differential scanning calorimetry, and accelerating rate calorimetry (Guide E1981). The results obtained by these approaches may be compared to the values provided by this practice.

Note 4—Not all reference materials are suitable for each measurement technique.

1.1 It is the purpose of this Practice to provide kinetic parameters for reference materials used for evaluation of thermal analysis methods, apparatus and software where enthalpy and temperature are measured. This Practice addresses both exothermic and endothermic, nth order and autocatalytic reactions.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.3 There is no International Organization for Standardization (ISO) equivalent to this standard.

1.4 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.
