1.1 该测试方法为石墨样品中的水分百分比提供了实用的测定方法。 1.2 以国际单位制表示的值应视为标准值。本标准不包括其他测量单位。 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建立适当的安全、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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 4.1 本试验方法仅适用于测定从大气中吸收水蒸气所产生的挥发性水分含量，并不旨在给出暴露于液态水污染的石墨的代表性水分数据。

1.1 This test method provides a practical determination for the percentage of moisture in a graphite sample. 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 This test method is applicable only for determination of the volatile moisture content resulting from adsorption of water vapor from the atmosphere, and is not intended to give representative moisture data for graphite that has been exposed to liquid water contamination.
