1.1 这些实践包括矿石和相关冶金材料（如矿山土壤、废石和尾矿）的消化，以便随后通过原子吸收光谱法（AAS）、电感耦合等离子体原子发射光谱法（ICP-AES）等溶液分析技术测定某些元素的酸可萃取含量（见试验方法 D1976 )和电感耦合等离子体质谱（ICP-MS）（见试验方法 D5673 ). 1.1.1 铝、锑、砷、钡、铍、铋、硼、镉、钙、铬、钴、铜、镓、铁、铅、锂、镁、锰、汞、钼、镍、磷、钾、钪、硒、银、钠、锶、铊、锡、钛、，钒和锌可从矿石和相关冶金材料中提取，用于通过溶液中元素的分析方法进行测定。 其他元素可从使用本规程生产的提取物中确定。 1.1.2 消化溶液中的实际元素定量可通过遵循其他适当ASTM标准下溶液中相关元素的各种测试方法来实现。 1.1.3 每种元素的检测限和线性含量范围取决于所采用的原子吸收、质谱或发射光谱测定技术，可以在所用仪器附带的手册或ASTM标准溶液分析方法中找到。由于固体样品的消化和稀释，在含量计算中考虑稀释系数。 1.1.4 通过这些方法从矿石和相关冶金材料中提取元素的程度取决于制备样品的物理和矿物学特征以及所用的消解方法。 1.2 消化实践按以下顺序出现: 小节 硝酸微波消解 7. 到 14 四酸全消化 15 到 21 1.3 以国际单位制表示的数值为标准。本标准不包括其他测量单位。 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。有关具体的危险说明，请参阅第节 11 和 20 . 1.5 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 这些实践主要用于测试材料是否符合成分规范和监测。部分提取矿石和相关冶金材料可以提供有关元素浸出可用性、水质变化或其他现场条件的信息。 4.2 假设这些实践的用户将是经过培训的分析员，能够熟练、安全地执行常见的实验室程序。预计工作将在配备适当的实验室进行，并遵循适当的废物处理程序。适当的质量控制实践，如指南中所述 E882 应遵守。

1.1 These practices cover the digestion of ores and related metallurgical materials, such as mine soil, waste rock and tailings, for subsequent determination of acid-extractable contents of certain elements by such solution analytical techniques as atomic absorption spectrometry (AAS), inductively coupled plasma atomic emission spectrometry (ICP-AES) (see Test Method D1976 ), and inductively coupled plasma mass spectrometry (ICP-MS) (see Test Method D5673 ). 1.1.1 Contents of aluminum, antimony, arsenic, barium, beryllium, bismuth, boron, cadmium, calcium, chromium, cobalt, copper, gallium, iron, lead, lithium, magnesium, manganese, mercury, molybdenum, nickel, phosphorus, potassium, scandium, selenium, silver, sodium, strontium, thallium, tin, titanium, vanadium and zinc can be extracted from ores and related metallurgical materials for determination by analytical methods for elements in solution. Other elements may be determined from extracts produced using this practice. 1.1.2 Actual element quantification in digested solutions can be accomplished by following the various test methods under other appropriate ASTM standards for element(s) of interest in solution. 1.1.3 The detection limit and linear content range for each element is dependent on the atomic absorption, mass spectrometry or emission spectrometric technique employed and may be found in the manual accompanying the instrument used or ASTM standard method for analysis of the solutions. Consider the dilution factor in content calculations due to digestion and dilution of solid samples. 1.1.4 The extent of extraction of elements from ores and related metallurgical materials by these practices is dependent upon the physical and mineralogical characteristics of the prepared sample and the digestion practice used. 1.2 The digestion practices appear in the following order: Sections Nitric Acid Microwave Digestion 7 to 14 Four-Acid Total Digestion 15 to 21 1.3 The values stated SI units are to be regarded as the standard. No other units of measurements 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 hazard statements, see Sections 11 and 20 . 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 These practices are primarily intended to test materials for compliance with compositional specifications and for monitoring. Partial extraction of ores and related metallurgical materials can provide information on the availability of elements to leaching, water quality changes, or other site conditions. 4.2 It is assumed that the users of these practices will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory and that proper waste disposal procedures will be followed. Appropriate quality control practices such as those described in Guide E882 shall be followed.
