1.1 本试验方法涵盖了分析煤炭、焦炭和煤炭和焦炭燃烧固体残留物中常见的主要和次要元素的程序。这些残留物可能是实验室灰、底灰、飞灰、烟气脱硫污泥和其他燃烧过程残留物。 注1: 有两项实验室间研究与本试验方法有关。第一次是在1997年进行的（RR:D05-1035） 2. 第二次试验于2007年进行（RR:D05-1032）。 3. 三氧化硫仅包括在2007年的研究中，该研究仅包括来自灰烬的燃烧残渣和来自焦炭的无燃烧残渣。 1.2 单位- 以国际单位制表示的数值应视为标准值。国际单位制后括号中给出的值仅供参考，不被视为标准值。 1.3 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。 1.4 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 煤和焦炭及其相关燃烧残留物的成分分析通常有助于评估其质量。与原煤中的质量分数相比，了解相关残留物的元素组成也有助于预测灰烬和炉渣的元素富集/贫化成分行为。 煤灰副产品的利用和潜在危险也可能取决于煤灰无机成分的化学成分和浸出能力。 5.2 实验室制备的灰烬的化学成分可能并不完全代表煤中矿物质的成分，也不代表商业规模燃烧煤产生的飞灰和炉渣的成分。

1.1 This test method covers a procedure for the analysis of the commonly determined major and minor elements in coal, coke, and solid residues from combustion of coal and coke. These residues may be laboratory ash, bottom ash, fly ash, flue gas desulfurization sludge, and other combustion process residues. Note 1: There are two interlaboratory studies associated with this test method. The first was conducted in 1997 ( RR:D05-1035) 2 and the second was conducted in 2007 ( RR:D05-1032). 3 Sulfur trioxide was only included in the 2007 study, and that study only included combustion residues derived from ash and no combustion residues derived from coke. 1.2 Units— The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 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 ====== 5.1 A compositional analysis of coal and coke and their associated combustion residues are often useful in assessing their quality. Knowledge of the elemental composition of the associated residues is also useful in predicting the elemental enrichment/depletion compositional behavior of ashes and slags in comparison to the mass fraction in the parent coal. Utilization of the ash by-products and hazardous potential may also depend on the chemical composition and leachability of the inorganic constituents of the coal ash. 5.2 The chemical composition of laboratory-prepared ash may not exactly represent the composition of mineral matter in coal or the composition of fly ash and slag resulting from commerical-scale burning of the coal.
