1.1 该测试方法提供了热重分析（TGA）技术来测定回收炭黑（rCB）中有机残留物的量、总碳含量和灰分含量。 1.2 该测试方法使用先前校准的、手动的或计算机辅助的TGA仪器。 1.3 单位- 以国际单位制表示的数值应视为标准。本标准中不包括其他计量单位。 1.4 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。 1.5 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 本试验方法用于生产质量控制，用于需要对不同材料进行成分分析或比较的研发目的。 5.2 该试验方法可能不适用于含有仅在550°C以上温度下分解或氧化的有机物质或分解温度为无机物质的rCB产品 ≤ 550°C。

1.1 This test method provides a thermogravimetric (TGA) technique to determine the amounts of organic residue, overall carbon content, and ash content in recovered carbon black (rCB). 1.2 This test method uses previously calibrated, manual, or computer-assisted TGA instrumentation. 1.3 Units— The values stated in SI units are to be regarded as the standard. No other units of measurement are included in 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 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 This test method is intended for use in quality control of production, for research and development purposes in which a compositional analysis or comparisons of different materials are needed. 5.2 This test method may not be suitable for rCB products containing either organic substances that decompose or oxidize only at temperatures of above 550°C or inorganic substances with decomposition temperatures ≤ 550°C.
