1.1 本实践的目的是为用于评估测量焓和温度的热分析方法、设备和软件的参考材料提供动力学参数。这种实践解决了放热和吸热两个问题， n th 顺序和自催化反应。 1.2 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.3 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 ====意义和用途====== 5.1 本实践中提供的动力学参数可用于评估测定参数的标准、仪器、技术或软件的性能（如试验方法 E698 , E1641 , E2041 或 E2070 )使用热分析技术，如差示扫描量热法和加速速率量热法（指南 E1981 ). 所获得的结果可以与该实践提供的值进行比较。 注4: 并非所有的参考材料都适用于每种测量技术。

1.1 The purpose of this practice is to provide kinetic parameters for reference materials used to evaluate thermal analysis methods, apparatus, and software where enthalpy and temperature are measured. This practice addresses both exothermic and endothermic, n th 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 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The kinetic parameters provided in this practice may be used to evaluate the performance of a standard, apparatus, technique, 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 may be compared to the values provided by this practice. Note 4: Not all reference materials are suitable for each measurement technique.
