ASTM Standard provides reference materials for kinetic parameters.
Press Release Summary:
June 21, 2011 - Users of standards involving kinetic parameters need reference materials to qualify individual laboratories and to validate procedures and software. Developed by Subcommittee E27.02 on Thermal Stability and Condensed Phases, ASTM E2781 will provide such parameters to accommodate apparatus configurations and kinetic models. Kinetic parameters, such as activation energy and pre-exponential factor, are used to estimate lifetime of products and to assess thermal safety of high-energy chemicals.

Reference Materials for Kinetic Parameters Presented in New ASTM International Standard
Press release date: June 17, 2011
o ASTM E698, Test Method for Arrhenius Kinetic Constants for Thermally Unstable Materials Using Differential Scanning Calorimetry and the Flynn/Wall/Ozawa Method;
o ASTM E1641, Test Method for Decomposition Kinetics by Thermogravimetry;
o ASTM E2041, Method for Estimating Kinetic Parameters by Differential Scanning Calorimetry Using the Borchardt and Daniels Method; and
o ASTM E2070, Test Method for Kinetic Parameters by Differential Scanning Calorimetry Using Isothermal Methods. Blaine says that ASTM E2781 can be used to select from the literature and to standardize the kinetic parameters for a series of materials that might be used for the evaluation of kinetic parameters. Developers of standards, procedures and tools for measurement of kinetic parameters will be the primary users of the standard. Users will include regulatory agencies, safety specialists interested in the storage and transportation of high energy materials, safety testing instrument manufacturers and safety software developers.
