1.1 本试验方法包括芳烃、其衍生物和相关化学品中硫的测定。 1.2 本试验方法适用于硫浓度为10 mg/kg的样品。检测限（LOD）为0.03 mg/kg S，定量限（LOQ）为0.1 mg/kg S。通过仔细的分析技术，该方法可用于成功分析当前范围以下的浓度（见 附录X1 ). 注1: LOD和LOQ使用ASTM研究报告RR:D16-160中的数据计算。 1.3 以下内容适用于确定使用该测试方法的测试结果是否符合适用规范，应根据四舍五入对结果进行四舍五舍五入- 非实践方法 第29页 . 1.4 以国际单位制表示的数值应视为标准。本标准不包括其他计量单位。 1.5 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。 有关具体的危险说明，请参阅第节 9 . 1.6 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====== 5.1 当原料中含有微量含硫物质时，石油和化学精炼中使用的一些工艺催化剂可能会中毒。该试验方法可用于测定工艺进料中的硫和成品中的硫，也可用于监管目的。

1.1 This test method covers the determination of sulfur in aromatic hydrocarbons, their derivatives, and related chemicals. 1.2 This test method is applicable to samples with sulfur concentrations to 10 mg/kg. The limit of detection (LOD) is 0.03 mg/kg S and the limit of quantitation (LOQ) is 0.1 mg/kg S. With careful analytical technique, this method can be used to successfully analyze concentrations below the current scope (see Appendix X1 ). Note 1: LOD and LOQ were calculated using data in ASTM Research Report RR:D16-1060. 1.3 The following applies for the purposes of determining the conformance of the test results using this test method to applicable specifications, results shall be rounded off in accordance with the rounding-off method of Practice E29 . 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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 Section 9 . 1.6 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 Some process catalysts used in petroleum and chemical refining can be poisoned when trace amounts of sulfur-bearing materials are contained in the feedstocks. This test method can be used to determine sulfur in process feeds, sulfur in finished products, and can also be used for purposes of regulatory control.
