1.1 本试验方法涵盖了两种程序的应用，用于测定焦炭在规定试验条件下下落时的抗破碎性能。 1.2 程序A， 当焦炭样品含有50 % 小于等于100毫米（4英寸）去除小于50毫米（2英寸）的焦炭后。程序A出现在章节中 6 – 9 . 1.3 程序B， 当焦炭样品含有 更多 超过50 % 100毫米（4英寸）去除小于50毫米（2英寸）的焦炭后。程序B出现在章节中 10 – 13 . 1.4 以国际单位制表示的数值应视为标准值。 括号中给出的值仅供参考。 1.5 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。 1.6 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 当根据其他焦炭的相关经验进行评估时，本试验中确定的值可用于指示给定焦炭在常规运输和处理过程中超出取样点的破碎程度。

1.1 This test method covers the application of two procedures for the determination of the property of coke of withstanding breakage when dropped under specified test conditions. 1.2 Procedure A, used when the coke sample contains 50 % or less of 100 mm (4 in.) after removal of coke smaller than 50 mm (2 in.). Procedure A appears in Sections 6 – 9 . 1.3 Procedure B, used when the coke sample contains more than 50 % 100 mm (4 in.) after removal of coke smaller than 50 mm (2 in.). Procedure B appears in Sections 10 – 13 . 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.5 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. 1.6 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 The values determined in this test, when evaluated in terms of pertinent experience with other cokes, may be used as indications of the extent to which a given coke will break in conventional transit and handling beyond the point of sampling.
