1.1 本试验方法涵盖了石油产品（包括含有添加剂的润滑油）和添加剂浓缩物中总硫的测定程序。本试验方法适用于沸点高于177的样品 摄氏度（350 °F）。表中所列以外的其他硫浓度 1.1.1 和 1.1.2 可以进行分析，但所述精度可能适用，也可能不适用。这些程序在熔炉中燃烧后使用IR检测或TCD。 1.1.1 程序A，红外线检测: 1.1.1.1 本程序适用于含硫质量分数在0之间的样品。 22 % 和24.2 %. 1.1.1.2 含硫质量分数在2.53之间的石油焦 % 至3.79 % 可以对硫进行分析。 1.1.2 程序B，TCD检测: 1.1.2.1 本程序适用于含硫质量分数在0.071之间的样品 % 和25.8 %. 1.1.2.2 含硫质量分数在0.19之间的石油焦 % 至6.38 % 可以对硫进行分析。 1.2 含硫质量分数在2.53之间的石油焦 % 至3.79 % 可以对硫进行分析。可以分析其他硫浓度，但规定的精度可能适用，也可能不适用。 注1: 这个 第1552天 – 本标准的08（2014）版本包含另外两个使用碘酸盐滴定的程序。根据2014年9月对D02.SC 3实验室进行的调查，由于这些程序不再在行业实验室中使用，因此正在删除。对于关于已删除过程的较早信息， 第1552天 – 08（2014）可能会被仔细阅读。 1.3 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 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 该试验方法提供了一种监测各种石油产品和添加剂硫含量的方法。这些知识可用于预测性能、处理或加工特性。在某些情况下，含硫化合物的存在对产品有益，并且监测硫的消耗可以提供有用的信息。在其他情况下，含硫化合物的存在对产品的加工或使用是有害的。

1.1 This test method covers procedures for the determination of total sulfur in petroleum products including lubricating oils containing additives, and in additive concentrates. This test method is applicable to samples boiling above 177 °C (350 °F). Other sulfur concentrations outside of those listed in 1.1.1 and 1.1.2 may be analyzed, but the precision stated may or may not apply. These procedures use IR detection or TCD following combustion in a furnace. 1.1.1 Procedure A, IR Detection: 1.1.1.1 This procedure is applicable to samples containing a mass fraction of sulfur between 0.22 % and 24.2 %. 1.1.1.2 Petroleum coke containing a mass fraction of sulfur between 2.53 % to 3.79 % sulfur may be analyzed. 1.1.2 Procedure B, TCD Detection: 1.1.2.1 This procedure is applicable to samples containing a mass fraction of sulfur between 0.071 % and 25.8 %. 1.1.2.2 Petroleum coke containing a mass fraction of sulfur between 0.19 % to 6.38 % sulfur may be analyzed. 1.2 Petroleum coke containing a mass fraction of sulfur between 2.53 % to 3.79 % sulfur may be analyzed. Other sulfur concentrations may be analyzed, but the precision stated may or may not apply. Note 1: The D1552 – 08 (2014) version of this standard contained two other procedures using iodate titrations. Since these procedures are no longer being used in the industry laboratories based on a survey of D02.SC 3 laboratories conducted in September 2014, they are being deleted. For earlier information on the deleted procedures, D1552 – 08 (2014) may be perused. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 This test method provides a means of monitoring the sulfur level of various petroleum products and additives. This knowledge can be used to predict performance, handling, or processing properties. In some cases the presence of sulfur compounds is beneficial to the product and monitoring the depletion of sulfur can provide useful information. In other cases the presence of sulfur compounds is detrimental to the processing or use of the product.
