1.1 本试验方法涵盖了一种高效液相色谱试验方法，用于测定在50℃范围内沸腾的航空煤油和石油馏分中的单芳烃和双芳烃含量 °C至300 °C，如Jet A或Jet A-1燃料。总芳烃含量由单个芳烃类型的总和计算得出。 注1: 最终沸点大于300的样品 °C含有三环芳烃和更高的多环芳烃化合物，不通过本试验方法测定，应通过试验方法进行分析 D6591 或其他合适的等效试验方法。 1.2 本试验方法适用于含有0.8 % 至44.0 % 按质量计，单芳烃，0.23 % 至6.20 % 按质量计，双芳烃和0.7 % 至50 % 按质量计的总芳烃。虽然该方法以m/m为单位生成结果，但也可以v/v为单位引用结果。 1.3 本试验方法的精度适用于含0.40%的煤油沸点馏分 % 至44.0 % 按质量计，单芳烃，0.02 % 至6.20 % 按质量计，双芳烃和0.40 % 至50.0 % 按质量计的总芳烃。如果以体积引用结果，则精度为0。 3. % 至41.4 % 按体积计，单芳烃，0.01 % 至5.00 % 按体积计，双芳烃和0.30 % 至46.3 % 按体积计的总芳烃。根据IP 367-1计算。 1.4 含有硫、氮和氧的化合物可能是干扰因素。单烯烃不干扰，但共轭双烯烃和聚烯烃（如果存在）是可能的干扰物。 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====== 5.1 芳烃类型的准确定量信息有助于确定石油过程对各种成品燃料生产的影响。该信息还可用于指示燃料质量和评估成品燃料的相对燃烧特性。

1.1 This test method covers a high performance liquid chromatographic test method for the determination of mono-aromatic and di-aromatic hydrocarbon contents in aviation kerosenes and petroleum distillates boiling in the range from 50 °C to 300 °C, such as Jet A or Jet A-1 fuels. The total aromatic content is calculated from the sum of the individual aromatic hydrocarbon-types. Note 1: Samples with a final boiling point greater than 300 °C that contain tri-aromatic and higher polycyclic aromatic compounds are not determined by this test method and should be analyzed by Test Method D6591 or other suitable equivalent test methods. 1.2 This test method is applicable to distillates containing from 0.8 % to 44.0 % by mass mono-aromatic hydrocarbons, 0.23 % to 6.20 % by mass di-aromatic hydrocarbons, and 0.7 % to 50 % by mass total aromatics. Although this method generates results in m/m, results may also be quoted in v/v. 1.3 The precision of this test method has been established for kerosene boiling range distillates containing from 0.40 % to 44.0 % by mass mono-aromatic hydrocarbons, 0.02 % to 6.20 % by mass di-aromatic hydrocarbons, and 0.40 % to 50.0 % by mass total aromatics. If results are quoted in volume, the precision is 0.3 % to 41.4 % by volume mono-aromatics, 0.01 % to 5.00 % by volume di-aromatics, and 0.30 % to 46.3 % by volume total aromatics. As calculated by IP 367-1. 1.4 Compounds containing sulfur, nitrogen, and oxygen are possible interferents. Mono-alkenes do not interfere, but conjugated di- and poly-alkenes, if present, are possible interferents. 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 ====== 5.1 Accurate quantitative information on aromatic hydrocarbon types can be useful in determining the effects of petroleum processes on production of various finished fuels. This information can also be useful for indicating the quality of fuels and for assessing the relative combustion properties of finished fuels.
