1.1 本试验方法包括测定在特定试验条件下释放的未净化活性炭和使用过的活性炭中气体产物（不包括水汽）的百分比。 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 当按本文所述测定挥发性物质时，可将其用作活性炭中碳化程度和吸附应用中使用的活性炭上挥发性材料负载程度的相对测量值。 5.2 结合其他信息，活性炭的挥发性物质可能有助于评估其在吸附应用中的性能。 5.3 其他用于测定固体挥发物含量的自动化方法，如使用热重分析仪（TGA），可以代替该试验方法，并获得同样可靠的结果。

1.1 This test method covers the determination of the percentage of gaseous products, exclusive of moisture vapor, present in virgin and used activated carbons which are released under specific conditions of the test. 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 Volatile matter, when determined as herein described, may be used as a relative measure of the extent of carbonization in an activated carbon and the extent of loading of volatile material on an activated carbon that has been used in an adsorption application. 5.2 Combined with other information, the volatile matter of an activated carbon may be useful in evaluating its performance in an adsorption application. 5.3 Other automated methods for the determination of the volatile content of solids, such as using a thermogravimetric analyzer (TGA), can be used in place of this test method with equally reliable results.
