1.1 本试验方法适用于石油产品沸程分布的测定。该试验方法适用于最终沸点为538的石油产品和馏分 °C（1000 °F）或更低。此测试方法仅限于具有 沸程 大于55.5 °C（100 °F），并且蒸汽压足够低以允许在环境温度下取样。 注1: 自 沸程 是两个温度之间的差值，只有1.8的常数 °F/°C用于将温度范围从一个单位系统转换为另一个单位。 1.1.1 程序A（章节 6- 14 )-- 除了火焰离子化检测器外，还可以选择更多的柱和分析条件，如填充柱和毛细管柱以及热导率检测器。分析时间范围为14 最小到60 最小。 1.1.2 程序B（章节 15– 23 )-- 仅限于3个毛细管柱，不需要稀释样品。此外，程序B不仅用于程序A中描述的样品类型，还用于分析含有生物柴油混合物B5、B10和B20的样品。使用程序B（加速 D2887 )，减少到约8 最小。 1.2 本试验方法不用于分析汽油样品或汽油成分。这些类型的样品必须通过试验方法进行分析 D7096 。 1.3 以国际单位制表示的数值应视为标准。SI单位后括号中给出的值仅供参考，不被视为标准值。 1.4 本标准并不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====== 5.1 石油馏分的沸程分布提供了对与石油精炼过程相关的原料和产品组成的深入了解。该测定的气相色谱模拟可用于取代用于控制精炼操作的传统蒸馏方法。经相关方共同同意，该测试方法可用于产品规格测试。 5.2 通过该试验方法获得的沸程分布基本上等同于通过真实沸点（TBP）蒸馏获得的沸度分布（见试验方法 D2892 )。它们不等同于低效率蒸馏的结果，例如用试验方法获得的结果 D86 或 D1160 。 5.3 用生物柴油混合物测试程序B，并报告了蔬菜和动物来源的FAME酯与超低硫柴油混合的沸点分布。

1.1 This test method covers the determination of the boiling range distribution of petroleum products. The test method is applicable to petroleum products and fractions having a final boiling point of 538 °C (1000 °F) or lower at atmospheric pressure as measured by this test method. This test method is limited to samples having a boiling range greater than 55.5 °C (100 °F), and having a vapor pressure sufficiently low to permit sampling at ambient temperature. Note 1: Since a boiling range is the difference between two temperatures, only the constant of 1.8 °F/°C is used in the conversion of the temperature range from one system of units to another. 1.1.1 Procedure A (Sections 6 – 14 )— Allows a larger selection of columns and analysis conditions such as packed and capillary columns as well as a Thermal Conductivity Detector in addition to the Flame Ionization Detector. Analysis times range from 14 min to 60 min. 1.1.2 Procedure B (Sections 15 – 23 )— Is restricted to only 3 capillary columns and requires no sample dilution. In addition, Procedure B is used not only for the sample types described in Procedure A but also for the analysis of samples containing biodiesel mixtures B5, B10, and B20. The analysis time, when using Procedure B (Accelerated D2887 ), is reduced to about 8 min. 1.2 This test method is not to be used for the analysis of gasoline samples or gasoline components. These types of samples must be analyzed by Test Method D7096 . 1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses after SI units are provided for information only and are not considered standard. 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 ====== 5.1 The boiling range distribution of petroleum fractions provides an insight into the composition of feedstocks and products related to petroleum refining processes. The gas chromatographic simulation of this determination can be used to replace conventional distillation methods for control of refining operations. This test method can be used for product specification testing with the mutual agreement of interested parties. 5.2 Boiling range distributions obtained by this test method are essentially equivalent to those obtained by true boiling point (TBP) distillation (see Test Method D2892 ). They are not equivalent to results from low efficiency distillations such as those obtained with Test Method D86 or D1160 . 5.3 Procedure B was tested with biodiesel mixtures and reports the Boiling Point Distribution of FAME esters of vegetable and animal origin mixed with ultra low sulfur diesel.
