1.1 本试验方法涵盖了石油馏分沸程分布的测定。本试验方法适用于通过本试验方法测量的大气压下初始沸点大于174°C（345°F）且最终沸点小于700°C（1292°F）（C10至C90）的石油馏分。 1.2 该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、原油）。含有非均相组分（如醇、醚、酸或酯）或残留物的材料不采用本试验方法进行分析。见测试方法 D2887 , D7096 ，或 D7169 为了可能适用于分析这些类型的材料。 1. 3. 以国际单位制表示的值应被视为标准值。以英寸-磅单位表示的值仅供参考，可能包含在括号中。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、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 中等和重质石油馏分的沸程分布提供了对与石油精炼工艺（例如加氢裂化、加氢处理、减粘裂化或脱沥青）相关的原料和产品组成的洞察。这种测定的气相色谱模拟可用于代替传统的蒸馏方法来控制精炼操作。经利益相关方共同同意，该测试方法可用于产品规格测试。 5.2 本试验方法扩大了气相色谱法测定沸程的范围，将试验方法范围之外的中重质石油馏分也包括在内 D2887 （538摄氏度）。 5.3 通过本试验方法获得的沸程分布尚未与通过低效蒸馏（如试验方法）获得的沸程分布进行相关性分析 D86 或 D1160 .

1.1 This test method covers the determination of the boiling range distribution of petroleum distillate fractions. The test method is applicable to petroleum distillate fractions having an initial boiling point greater than 174 °C (345 °F) and a final boiling point of less than 700 °C (1292 °F) (C10 to C90) at atmospheric pressure as measured by this test method. 1.2 The test method is not applicable for the analysis of petroleum or petroleum products containing low molecular weight components (for example naphthas, reformates, gasolines, crude oils). Materials containing heterogeneous components (for example alcohols, ethers, acids, or esters) or residue are not to be analyzed by this test method. See Test Methods D2887 , D7096 , or D7169 for possible applicability to analysis of these types of materials. 1.3 The values stated in SI units are to be regarded as standard. The values stated in inch-pound units are for information only and may be included as parenthetical values. 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 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 medium 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 .
