1.1 该测试方法给出了方程，以使应用RDF分析程序得到的分析数据能够在常用的各种不同基础上表达。这些基础是:收到时；干的干燥、无灰；和其他。 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。 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====== 4.1 RDF的生产者和用户可以使用此测试方法将实验室数据从一种基础转换为另一种基础。

1.1 This test method gives equations to enable analytical data from the application of RDF analysis procedures to be expressed on various different bases in common use. Such bases are: as-received; dry; dry, ash-free; and others. 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. 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 ====== 4.1 This test method is available to producers and users of RDF to use in converting laboratory data from one basis to another.
