1.1 该试验方法包括含游离水样品的制备程序（总水分样品的空气干燥损失（ADL））和绿色石油焦总水分含量的测定。 1.2 单位-- 以国际单位制表示的数值应视为标准。SI单位后括号中给出的值仅供参考，不视为标准值。 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。 1.4 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 水分增加焦炭的质量，没有任何用处。在绿色石油焦的采购和销售中，水分含量的知识是重要的，这两项工作都是在干燥的基础上进行的。 5.2 为 烘箱法 旨在明确测定生石油焦的总水分。当其他技术或修改未达成一致时，生产商、销售商和消费者可使用该标准进行确定。 5.3 这个 准备程序 仅当样品含有游离水时使用。获得焦炭源的代表性样品是通过存在游离水来混合的。

1.1 This test method covers both the preparation procedure for samples containing free water (air drying loss (ADL) on gross moisture samples) and the determination of the gross moisture content of green petroleum coke. 1.2 Units— The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered 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 Moisture adds mass to the coke and serves no useful purpose. A knowledge of the moisture content is important in the purchase and sale of green petroleum coke, both of which are conducted on a dry basis. 5.2 The collection of the sample as specified for the Drying Oven Method is intended for the express purpose of determining the total moisture of green petroleum coke. The standard is available to producers, sellers, and consumers for determination when other techniques or modifications are not mutually agreed on. 5.3 The Preparation Procedure is used only when sample contains free water. Obtaining a representative sample of a coke source is compounded by the presence of free water.
