1.1 本试验方法涵盖垃圾衍生燃料（RDF）分析样品中残留水分的测量。它用于在干基上计算对分析RDF样品进行的其他测定。它与空气干燥湿度结果一起用于计算总湿度( 注1 ). 总水分用于计算接收值或对样品进行的其他分析。 注1: 在某些情况下，RDF水分可能在RDF分析样品制备程序的尺寸减小步骤中发生变化。除非进行适当的校正，否则这种水分变化将影响从空气中计算出的总水分值的准确性- 干燥和残留水分的结果。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 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。 有关更具体的预防信息，请参阅第节 7. . 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 本试验方法中规定的样品程序旨在测定RDF分析样品中的残留水分。 5.2 残余水分值用于校正已确定的分析结果，如总热值、硫和灰分至干燥样品的基准结果。

1.1 This test method covers the measurement of residual moisture in refuse-derived fuel (RDF) analysis samples. It is used to calculate on a dry basis other determinations performed on analysis RDF samples. It is used with air-dry moisture results to calculate total moisture ( Note 1 ). The total moisture is used to calculate as-received values or other analyses performed on a sample. Note 1: In some instances, RDF moisture may change during size-reduction steps of the RDF analysis sample preparation procedure. This moisture change, unless suitable corrections are made, will affect the accuracy of the total moisture value as calculated from the air-dry and residual moisture results. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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. For more specific precautionary information, see Section 7 . 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 The procedure in this test method for a sample as specified herein is intended for the purpose of determining the residual moisture present in a RDF analysis sample. 5.2 The residual moisture value is used to correct as-determined analysis results such as gross heating value, sulfur, and ash to dry sample basis results.
