Standard Test Method for Free-Swelling Index of Coal 煤的自由膨胀指数的标准试验方法
发布日期: 2024-07-01
1.1 此测试方法 2. 是一种小规模的经验测试,用于获得有关煤的自由膨胀特性的信息。该结果可以用作煤作为燃料燃烧时的结块特性的指示。不建议将此试验作为测定焦炉中煤膨胀的方法。 1.2 单位-- 以国际单位制或非国际单位制表示的数值应单独视为标准。每个系统中规定的值不一定是完全相等的;因此,为了确保符合标准,每个系统应独立使用,并且不得将两个系统的值组合使用。 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。 1.4 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====== 3.1 该试验方法除了指示煤作为燃料燃烧时的结块特性外,还可用于广泛指示煤的氧化程度。
1.1 This test method 2 is a small-scale, empirical test for obtaining information regarding the free-swelling properties of a coal. The results may be used as an indication of the caking characteristic of the coal when burned as a fuel. This test is not recommended as a method for the determination of expansion of coals in coke ovens. 1.2 Units— The values stated in either SI units or non-SI 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. 1.3 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 ====== 3.1 This test method, in addition to indicating the caking properties of a coal when burned as a fuel, can be used to give a broad indication of the degree of oxidation of a coal.
