1.1 本试验方法包括两个程序，用于测定小于37.5的碎煤的体积密度 毫米[1.5 在中。]在尺寸上，如装入焦炉，如下所示: 1.1.1 程序A- 确定未压缩体积密度的锥过程。 1.1.1.1 标准方法- 程序使用115 毫米[4.5 在中。]溜槽开口和尺寸为305的测量箱 毫米x 305 毫米x 305 毫米[12.0 在里面x 12.0 在里面x 12.0 英寸。]。 1.1.1.2 替代方法- 程序使用203 毫米[8.0 在中。]溜槽开口和尺寸为203的测量箱 毫米x 203 毫米x 305 毫米[8.0 在里面x 8.0 在里面x 12.0 在中。]对于总水分大于7的煤 %. 1.1.2 程序B- 测定压实体积密度的落煤程序，与焦炉中获得的实际体积密度相当。 1.2 本试验方法不适用于锅炉厂中使用的煤粉的试验，也不适用于测定储煤堆中煤炭的体积密度。 1.3 单位- 以国际单位制或英寸-磅单位表示的数值应单独视为标准值。每个系统中规定的值不一定是精确的等价物；因此，为确保符合本标准，每个系统应独立使用，且两个系统的值不得组合。 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。 1.5 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====== 3.1 本试验方法涉及碎煤的压实，以确定其压实或未压实的体积密度，用于装料焦炉等目的。

1.1 This test method covers two procedures for determining the bulk density of crushed coal less than 37.5 mm [1.5 in.] in size, such as is charged into coke ovens, as follows: 1.1.1 Procedure A— The cone procedure for determining an uncompacted bulk density. 1.1.1.1 Standard Method— Procedure employs the use of a 115 mm [4.5 in.] chute opening and a measuring box having dimensions of 305 mm x 305 mm x 305 mm [12.0 in. x 12.0 in. x 12.0 in.]. 1.1.1.2 Alternate Method— Procedure employs the use of a 203 mm [8.0 in.] chute opening and a measuring box having dimensions of 203 mm x 203 mm x 305 mm [8.0 in. x 8.0 in. x 12.0 in.] for coals with a total moisture greater than 7 %. 1.1.2 Procedure B— The dropped-coal procedure for determining a compacted bulk density, comparable to actual bulk densities attained in coke ovens. 1.2 This test method is not applicable to the testing of powdered coal as used in boiler plants, nor to the determination of the bulk density of coal in storage piles. 1.3 Units— The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily exact equivalents; therefore, to ensure conformance with the standard, each system shall be used independently of the other, and values from the two systems shall not be combined. 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. 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 ====== 3.1 This test method concerns the compaction of crushed coal to determine either its compacted or uncompacted bulk density, for purposes such as charging coke ovens.
