1.1 本试验方法涵盖了石油产品中硫含量的测定，范围为0.02 mg/kg至10.00 毫克/千克。 1.2 本试验方法可通过稀释扩展至更高浓度。 1.3 本试验方法适用于沸点在30℃之间的液体 °C和371 °C（86 °F和700 °F）。可分析的材料包括石脑油、煤油、酒精、蒸汽冷凝液、各种馏分、喷气燃料、苯和甲苯。 1.4 以国际单位制表示的数值应视为标准值。括号中给出的值仅供参考。 1.4.1 记录器的某些规格（请参阅 5.5 )除外。 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。 1.6 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 在许多炼油过程中，原料油中的硫含量低可能会毒害昂贵的催化剂。该试验方法可用于监测此类石油馏分中的硫含量。 4.2 本试验方法也可用作成品中硫测定的质量控制工具。

1.1 This test method covers the determination of sulfur in petroleum products in the range from 0.02 mg/kg to 10.00 mg/kg. 1.2 This test method may be extended to higher concentration by dilution. 1.3 This test method is applicable to liquids whose boiling points are between 30 °C and 371 °C (86 °F and 700 °F). Materials that can be analyzed include naphtha, kerosine, alcohol, steam condensate, various distillates, jet fuel, benzene, and toluene. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.4.1 Certain specifications for the recorder (see 5.5 ) are excepted. 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. 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 ====== 4.1 In many petroleum refining processes, low levels of sulfur in feed stocks may poison expensive catalysts. This test method can be used to monitor the amount of sulfur in such petroleum fractions. 4.2 This test method may also be used as a quality-control tool for sulfur determination in finished products.
