1.1 该试验方法包括观察在受控、轻度还原和氧化气氛中以特定速率加热时，由RDF灰制备的三角锥（锥体）达到并通过某些熔融和流动阶段的温度。 1.2 试验方法是经验的，必须严格遵守要求和条件，才能获得可重复的温度，并使不同的实验室能够获得可比较的结果。 1.3 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 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。 1.5 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====== 4.1 本标准用于测定RDF产生的灰烬的熔融性。 4.2 灰熔融性数据的局限性-- 灰熔融性数据经常被忽略- 解释。在实践中，燃烧设备的类型、燃烧速率、火床或火球的温度和厚度、RDF中形成灰的矿物质的分布以及熔融灰的粘度可能比实验室测试确定的灰熔融性特征更能影响灰的行为。此外，RDF应用燃烧过程中存在的条件非常复杂，不可能在小规模实验室测试中完全复制。因此，该分析应被视为实证分析，数据仅为定性分析。

1.1 This test method covers the observation of the temperatures at which triangular pyramids (cones) prepared from RDF ash attain and pass through certain stages of fusing and flow when heated at a specific rate in controlled, mildly reducing, and oxidizing atmospheres. 1.2 The test method is empirical, and strict observance of the requirements and conditions is necessary to obtain reproducible temperatures and enable different laboratories to obtain comparable results. 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 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 ====== 4.1 This standard is for determining the fusibility of ash produced from RDF. 4.2 Limitations of Ash Fusibility Data— Ash fusibility data are often over-interpreted. In practice, types of burning equipment, rate of burning, temperature and thickness of fire bed or ball, distribution of ash forming mineral matter in the RDF, and viscosity of the molten ash may influence ash behavior more than the ash fusibility characteristics determined by the laboratory test. Also, conditions existing during applied combustion of RDF are so complex that they are impossible to duplicate completely in a small-scale laboratory test. Therefore, the analysis should be considered an empirical one and the data only qualitative.
