1.1 本试验方法包括使用火焰离子化检测通过毛细管气相色谱法测定石油产品的沸腾范围分布。本标准试验方法是通过协调两种试验方法（试验方法）而制定的 D6352 和IP 480。由于这两种方法涵盖的范围相同，并且包括非常相似的操作条件，人们一致认为，单一标准方法将有利于全球模拟蒸馏界。 1.2 本试验方法不适用于分析含有低分子量成分的石油或石油产品（例如石脑油、重整油、汽油、柴油）。含有杂原子的成分（例如醇类、醚类、酸类或酯类）或残留物不采用本试验方法进行分析。 见测试方法 D7096 , D2887 或 D7213 对于这些类型材料分析的可能适用性。该方法也不适用于无法从气相色谱柱中完全洗脱并留下残留物的样品。原油和残渣等样品见试验方法 D5307 和 D7169 . 1.3 本试验方法适用于初始沸点高于100的馏出物 ºC，最终沸点低于735 ºC（碳110）；例如，馏出物（IBP > 100 °C），基础油和润滑基础油。 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。 1.5 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 中等和重质石油馏出物馏分的沸腾范围分布可以深入了解与石油精炼过程（例如，加氢裂化、加氢处理、减粘裂化或脱沥青）相关的原料和产品的组成。该测定的气相色谱模拟可用于取代传统蒸馏方法，以控制精炼操作。经相关方一致同意，本测试方法可用于产品规格测试。 5.2 本试验方法扩展了气相色谱法测定沸腾范围的范围，包括馏出物（IBP > 100 °C）和超出试验方法范围的重石油馏分 D2887 (538 °C）。 5.3 未分析通过该试验方法获得的沸腾范围分布与通过低效蒸馏获得的沸腾范围分布的相关性，例如通过试验方法获得的沸腾范围分布 D86 或 D1160 . 本试验方法不要求这些物理蒸馏和模拟蒸馏之间的一致性。将继续努力解决这一问题。当确定问题的成功解决方案时，将相应修改此测试方法。

1.1 This test method covers the determination of the boiling range distribution of petroleum products by capillary gas chromatography using flame ionization detection. This standard test method has been developed through the harmonization of two test methods, Test Method D6352 and IP 480. As both of these methods cover the same scope and include very similar operating conditions, it was agreed that a single standard method would benefit the global simulated distillation community. 1.2 This test method is not applicable for the analysis of petroleum or petroleum products containing low molecular weight components (for example naphthas, reformates, gasolines, diesel). Components containing hetero atoms (for example alcohols, ethers, acids, or esters) or residue are not to be analyzed by this test method. See Test Methods D7096 , D2887 , or D7213 for possible applicability to analysis of these types of materials. This method is also not suitable for samples that will not elute completely from the gas chromatographic column, leaving residues. For such samples as crude oils and residues, see Test Methods D5307 and D7169 . 1.3 This test method is applicable to distillates with initial boiling points above 100 ºC and final boiling points below 735 ºC (carbon 110); for example, distillates (IBP > 100 °C), base oils and lubricating base stocks. 1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.5 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 medium and heavy petroleum distillate fractions provides an insight into the composition of feed stocks and products related to petroleum refining processes (for example, hydrocracking, hydrotreating, visbreaking, or deasphalting). 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 This test method extends the scope of boiling range determination by gas chromatography to include distillates (IBP > 100 °C) and heavy petroleum distillate fractions beyond the scope of Test Method D2887 (538 °C). 5.3 Boiling range distributions obtained by this test method have not been analyzed for correlation to those obtained by low efficiency distillation, such as with Test Method D86 or D1160 . This test method does not claim agreement between these physical distillations and simulated distillation. Efforts to resolve this question will continue. When successful resolutions of the questions are determined, this test method will be revised accordingly.
