1.1 这些测试方法包括木材燃料的近似和最终分析，以及通过规定的测试方法取样和制备并根据ASTM既定程序进行分析的木材燃料的总热值的测定。如本文所述的测试方法可用于建立燃料的等级，显示可燃成分与不可燃成分的比率，提供购买和销售的基础，以及评估选矿或其他目的。 1.2 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.3 本国际标准是根据《关于制定国际标准的原则的决定》中确定的国际公认的标准化原则制定的s，世界贸易组织技术性贸易壁垒（TBT）委员会发布的指南和建议。 ======意义和用途====== 4.1 本文所述的这些测试分析方法可用于木材燃料的近似分析、最终分析和总热值的测定。

1.1 These test methods cover the proximate and ultimate analysis of wood fuels and the determination of the gross caloric value of wood fuels sampled and prepared by prescribed test methods and analyzed according to ASTM established procedures. Test methods as herein described may be used to establish the rank of fuels, to show the ratio of combustible to incombustible constituents, to provide the basis for buying and selling, and to evaluate for beneficiation or for other purposes. 1.2 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. 1.3 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 These test methods of analysis described herein can be used for the proximate analysis, ultimate analysis, and the determination of the gross caloric value of wood fuels.
