1.1 本试验方法适用于通过能量色散X射线荧光（EDXRF）光谱法测定工业炉使用的典型液体危险废物燃料（LHWF）中的微量元素浓度。 1.2 该试验方法已成功用于大量LHWF样品，这些样品是溶剂、油、油漆和颜料的混合物，用于测定以下元素:Ag、As、Ba、Cd、Cr、Hg、Ni、Pb、Sb、Se和Tl。 1.3 本试验方法也可适用于上述未列出的元素，以及除用作LHWF的有机液体外的有机液体中微量金属的分析。 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。 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====== 4.1 微量元素分析通常是使用LHWF的设施的监管和工艺特定要求。 通过适当的仪器标准化、设置和质量控制，该测试方法为用户提供了一种准确、快速、无损的微量元素测定方法。

1.1 This test method applies to the determination of trace element concentrations by energy-dispersive X-ray fluorescence (EDXRF) spectrometry in typical liquid hazardous waste fuels (LHWF) used by industrial furnaces. 1.2 This test method has been used successfully on numerous samples of LHWF that are mixtures of solvents, oils, paints, and pigments for the determination of the following elements: Ag, As, Ba, Cd, Cr, Hg, Ni, Pb, Sb, Se, and Tl. 1.3 This test method also may be applicable to elements not listed above and to the analysis of trace metals in organic liquids other than those used as LHWF. 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. 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 ====== 4.1 The analysis of trace elements is often a regulatory and process-specific requirement for facilities utilizing LHWF. With proper instrument standardization, set-up, and quality control, this test method provides the user an accurate, rapid, nondestructive method for trace element determinations.
