1.1 本试验方法包括测定用于煅烧焦炭的材料量，以控制与焦炭处理和运输相关的灰尘。 1.2 该测试方法仅限于那些可溶于溶剂的材料，该溶剂可用于索氏提取型设备，例如二氯甲烷。 注1: 在编写本程序时，二氯甲烷是最常用的除尘控制油溶剂。然而，甲苯和甲基氯仿在所有测试的焦炭上都得到了同样的结果，这些焦炭只包括那些喷有芳香或蜡质材料的焦炭。 1.3 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。 有关具体警告说明，请参阅第节 7. 。 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 该试验旨在量化添加到煅烧焦炭中的防尘材料的量。该防尘材料应用于煅烧焦炭，有助于保持无尘环境。它通常没有其他有用的目的。它增加了焦炭的质量，并可能对由处理过的焦炭制成的碳和石墨制品的质量产生负面影响。由于这些原因，焦炭客户想要知道焦炭上的灰尘控制材料的量，并且可以指定最大水平。

1.1 This test method covers the determination of the amount of material applied to calcined coke to control dust associated with coke handling and transportation. 1.2 This test method is limited to those materials that are soluble in a solvent that can be used in a Soxhlet extraction type of apparatus such as methylene chloride (dichloro-methane). Note 1: Methylene chloride is the most popular solvent for removing dust control oil at the time this procedure is being written. Toluene and methyl chloroform, however, have been used with equal results on all cokes tested which have included only those sprayed with aromatic or waxy materials. 1.3 The values stated in SI units are to be regarded as 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. For specific warning statements, see Section 7 . 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 The test is designed to quantify the amount of dust control material added to calcined coke. The dust control material is applied to calcined coke to help maintain a dust-free environment. It generally serves no other useful purpose. It adds mass to the coke and can have a negative effect on the quality of carbon and graphite artifacts made from the treated coke. For these reasons the coke customer wants to know the amount of dust control material on the coke and can specify a maximum level.
