1.1 本实施规程的目的是为用于评估热重分析方法、仪器和软件（其中测量分解质量损失和相关温度）的参考材料提供动力学参数。本实践涉及 n 四阶反应。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户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（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本规程中提供的动力学参数可用于评估标准、仪器、技术或软件的性能，以确定平均参数（例如试验方法 E1641 和 E2958年 ). 通过这些方法获得的结果可以与本规程提供的值进行比较。

1.1 It is the purpose of this practice to provide kinetic parameters for reference material(s) to be used for evaluation of thermogravimetry methods, apparatus, and software where decomposition mass loss and associated temperature are measured. This practice addresses n th order 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 determined mean parameters (such as Test Methods E1641 and E2958 ). The results obtained by these approaches may be compared to the values provided by this practice.
