1.1 本试验方法描述了测定烧结铁矿球团和直接还原铁压碎强度的方法。本试验方法不包括圆柱形团块和型煤。 1.2 以国际单位制表示的数值应视为标准。括号中的值仅供参考。 1.3 本试验得出的结果应与ISO 4700中的结果相似（见 附录X1 详细信息）。 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====== 5.1 压碎强度有助于球团生产商确定与球团生产相关的质量问题。 5.2 在高炉和气基直接还原装置中，球团消费者通常将抗压强度用作性能的质量指标。

1.1 This test method describes a method for determining the crushing strength of fired iron ore pellets and direct-reduced iron. Cylindrical agglomerates and briquettes are not covered by this test method. 1.2 The values as stated in SI units are to be regarded as the standards. The values in parentheses are given for information only. 1.3 Results given by this test should be similar to those from ISO 4700 (see Appendix X1 for details). 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 ====== 5.1 The crushing strength aids the pellet producer in the determination of quality problems associated with the production of pellets. 5.2 The crushing strength is often used by the pellet consumer as a quality indicator for performance in the blast furnace and gas-based direct reduction plants.
