1.1 本试验方法涵盖了测定原油样品中总汞含量的程序。本试验方法可用于天然和加工液体及石油产品（汽油、石脑油等）中总汞的测定。 1.2 本试验方法可适用于含量在5.0%之间的样品 纳克/毫升至350 纳克/毫升汞。结果可以转换为质量基础。 1.3 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。 1.4 这项工作已发表在《原子光谱法测定原油中的汞》上 2. 1.5 警告 -许多监管机构已将汞指定为一种危险物质，可导致严重的医疗问题。汞或其蒸汽已被证明对健康有害，并对材料具有腐蚀性。 处理汞和含汞产品时要小心。有关更多信息，请参阅适用的产品安全数据表（SDS）。当地或国家法律禁止销售汞或含汞产品，或两者兼有。用户必须确定其所在地销售的合法性。 1.6 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。 1.7 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 原油精炼过程中汞的排放是一个环境问题。汞的排放也可能污染精炼产品，并与铝等金属形成汞合金。 5.2 当根据本程序分析代表性试验部分时，总汞代表样品中的浓度。

1.1 This test method covers the procedure to determine the total mercury content in a sample of crude oil. This test method can be used for total mercury determination in natural and processed liquid and oil products (gasoline, naphtha, etc.). 1.2 This test method may be applied to samples containing between 5.0 ng/mL to 350 ng/mL of mercury. The results may be converted to mass basis. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 This work has been published in “Determination of Mercury in Crude Oil by Atomic Spectroscopy.” 2 1.5 WARNING —Mercury has been designated by many regulatory agencies as a hazardous substance that can cause serious medical issues. Mercury, or its vapor, has been demonstrated to be hazardous to health and corrosive to materials. Use Caution when handling mercury and mercury-containing products. See the applicable product Safety Data Sheet (SDS) for additional information. The potential exists that selling mercury or mercury-containing products, or both, is prohibited by local or national law. Users must determine legality of sales in their location. 1.6 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. 1.7 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 emission of mercury during crude oil refining is an environmental concern. The emission of mercury may also contaminate refined products and form amalgams with metals, such as aluminum. 5.2 When representative test portions are analyzed according to this procedure, the total mercury is representative of concentrations in the sample.
