1.1 本试验方法描述了测定活性炭总灰分含量的程序。 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====== 4.1 在特定的最终用途中，灰的数量和组成可能会影响活性炭的性能和某些预期特性。 4.2 其他自动测定灰分含量的方法，如在流动空气或氧气中在热重分析仪（TGA）中燃烧碳，可以代替该试验方法。测试方法中描述了一种合适的方法 D7582 . 对于活性炭灰分含量的测定，请遵循试验方法13.5.3中的程序 D7582 ，但13.4.3中的炉膛温度应为650±25 °C。马弗炉法应视为参考试验方法。

1.1 This test method describes a procedure for the determination of total ash content of activated carbon. 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 ====== 4.1 In specific end uses, the amount and composition of the ash may influence the capabilities and certain desired properties of activated carbon. 4.2 Other automated methods for determination of ash content, such as combusting the carbon in a thermogravimetric analyzer (TGA) in flowing air or oxygen, can be used in place of this test method. A suitable method is described in Test Methods D7582 . For determination of the ash content of activated carbon, follow the procedure in 13.5.3 of Test Methods D7582 , with the exception that the furnace temperature in 13.4.3 shall be 650 ± 25 °C. The muffle furnace method shall be considered the reference test method.
