1.1 本试验方法包括测定石油产品和生物柴油配方B5、B10和B20的沸腾范围分布。适用于最终沸点不超过538的石油馏分 通过本试验方法测量的大气压力为°C或更低。初始沸点和最终沸点之间的差值应大于55 °C。 1.2 本试验方法不适用于分析含有低分子量成分的石油馏分（例如石脑油、重整油、汽油、全馏分原油）。含有非均质混合物（例如，醇类、醚类、酸类或酯类，生物柴油除外）或残留物的材料不应使用本试验方法进行分析。 见测试方法 D3710 , D7096 , D6352 或 D7169 . 1.3 本试验方法采用模拟蒸馏法的原理。本试验方法使用气相色谱成分，使样品之间的整个分析在5分钟内进行 最小值或更少。在这些仪器中，以传统气相色谱仪的10到15倍的速率直接加热色谱柱，从而缩短了样品之间的分析时间。 1.4 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4.1 例外情况- 附录X1 包括华氏温度，仅供参考。 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 石油馏出物馏分的沸腾范围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。 通过该测试方法获得的快速分析时间的一个主要优点是增加了产品吞吐量，并将实验室测试时间减少了至少3倍。经相关方相互同意，这种沸腾范围的气相色谱测定可用于取代传统蒸馏方法，以控制精炼操作和进行产品规格测试。 5.2 通过本试验方法获得的沸腾范围分布基本上等同于通过真实沸点（TBP）蒸馏获得的沸腾范围分布（见试验方法 D2892 ). 它们不等同于低效蒸馏的结果，例如通过试验方法获得的结果 D86 或 D1160 .

1.1 This test method covers the determination of the boiling range distribution of petroleum products and biodiesel formulations, B5, B10, and B20. It is applicable to petroleum distillates having a final boiling point not greater than 538 °C or lower at atmospheric pressure as measured by this test method. The difference between the initial boiling point and the final boiling point shall be greater than 55 °C. 1.2 The test method is not applicable for analysis of petroleum distillates containing low molecular weight components (for example naphthas, reformates, gasolines, full range crude oils). Materials containing heterogeneous mixtures (for example, alcohols, ethers, acids or esters, except biodiesels) or residue are not to be analyzed by this test method. See Test Methods D3710 , D7096 , D6352 , or D7169 . 1.3 This test method uses the principles of simulated distillation methodology. This test method uses gas chromatographic components that allow the entire analysis from sample to sample to occur in 5 min or less. In these instruments the column is heated directly at rates 10 to 15 times that of a conventional gas chromatograph and thus the analysis time is reduced from sample to sample. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4.1 Exception— Appendix X1 includes temperatures in Fahrenheit for information only. 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 The boiling range distribution of petroleum distillate fractions provides an insight into the composition of feed stocks and products related to petroleum refining processes. A major advantage of the fast analysis time obtained by this test method is increasing product through put and reduced lab testing time by a minimum factor of 3. This gas chromatographic determination of boiling range may be used to replace conventional distillation methods for control of refining operations and 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 .
