1.1 本试验方法涵盖了用于根据有机组分和矿物质的体积分数（如果需要）通过系统手动点计数确定煤样品物理成分的设备和技术。 1.2 术语 重量 由于已确立的行业惯例，本测试方法暂时使用。该词用于表示力和质量，必须小心确定每种情况下的含义（力的国际单位制单位为牛顿，质量的国际单位为千克）。 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====== 5.1 煤的物理组分的体积分数用于煤层对比和煤的表征，用于碳化、气化、液化和燃烧过程。 5.2 该测试方法用于科学和工业研究，而非合规性或仲裁测试。

1.1 This test method covers the equipment and techniques used for determining the physical composition of a coal sample in terms of volume fraction of the organic components and of mineral matter, if desired by systematic manual point count. 1.2 The term weight is temporarily used in this test method because of established trade usage. The word is used to mean both force and mass and care must be taken to determine which is meant in each case (the SI unit for force is newton and for mass, kilogram). 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 The volume fraction of physical components of coal is used as an aid in coal seam correlation and in the characterization of coals for their use in carbonization, gasification, liquefaction, and combustion processes. 5.2 This test method is for use in scientific and industrial research, not compliance or referee tests.
