1.1 本试验方法用于测定垃圾衍生燃料（RDF）样品中的总碳和氢。碳和氢都是在一次分析中确定的。该测试方法得出了分析的RDF中碳和氢的总百分比，结果不仅包括有机物中的碳和氢，还包括矿物碳酸盐中存在的碳和伴随分析样品的游离水分中存在的氢，以及作为水合水存在的氢。 注1: 人们认识到，从本试验程序中得出的数据的某些技术应用可能证明有必要进行额外的校正。这些校正可能涉及对以碳酸盐形式存在的碳、伴随分析样品的游离水分的氢以及以水合水形式存在的计算氢的补偿。 1.2 本试验方法可适用于可制备实验室分析样品的任何废料。 1.3 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 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。 有关具体的预防说明，请参阅第节 8. . 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====== 5.1 本标准旨在提供一种测定RDF分析样品中碳和氢的重量百分比的方法。 5.2 碳和氢是RDF的成分，当确定时，可用于计算RDF燃烧特性。

1.1 This test method is for the determination of total carbon and hydrogen in a sample of refuse-derived fuel (RDF). Both carbon and hydrogen are determined in one analysis. This test method yields the total percentages of carbon and hydrogen in RDF as analyzed and the results include not only carbon and hydrogen in the organic matter, but also the carbon present in mineral carbonates and the hydrogen present in the free moisture accompanying the analysis sample as well as hydrogen present as water of hydration. Note 1: It is recognized that certain technical applications of the data derived from this test procedure may justify additional corrections. These corrections could involve compensation for the carbon present as carbonates, the hydrogen of free moisture accompanying the analysis sample, and the calculated hydrogen present as water of hydration. 1.2 This test method may be applicable to any waste material from which a laboratory analysis sample can be prepared. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 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. For specific precautionary statements, see Section 8 . 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 This standard is intended to provide a method for determining the weight percent of carbon and hydrogen in an RDF analysis sample. 5.2 Carbon and hydrogen are components of RDF and, when determined, can be used for calculating RDF combustion characteristics.
