1.1 本试验方法包括使用高温气相色谱法测定原油和残渣的沸点分布和切点间隔。残留物的量（或样品回收率）使用外部标准测定。 1.2 该测试方法将模拟蒸馏的适用性扩展到未完全从色谱系统洗脱的样品。该试验方法用于确定720℃下的沸点分布 °C。该温度对应于 n -C 100 。 1.3 本试验方法用于测定原油的沸点分布。 该测试方法使用带有薄膜的毛细管柱，这会导致C的不完全分离 4. -C 8. 在存在大量二硫化碳的情况下，并因此产生对应于该洗脱间隔的不可靠的沸点分布。此外，在二硫化碳洗脱过程中，检测器对碳氢化合物洗脱的响应猝灭，导致C中沸腾分布的定量分析不可靠 4. -C 8. 区域由于检测器不定量测量二硫化碳，因此仅使用溶剂注入从样品中减去二硫化碳，并通过猝灭因子对该区域进行校正，从而大致确定净色谱面积。 可能需要对样品的轻端部分进行单独的、更高分辨率的气相色谱（GC）分析，以获得测试方法中所述区间内沸点曲线的更准确描述 D7900 （参见 附录X1 )。 1.4 该测试方法还旨在获得其他不完全洗脱样品的沸点分布，如大气残留物、真空残留物等，其特征是样品组分从溶剂中溶解。 1.5 试验方法中沸程分布结果之间的相关性 D2892 ，以及通过该方法确定的重量百分比数据，如 附录X2 。 1.6 本试验方法不适用于含有非均质组分的材料（如聚酯和聚烯烃）的分析。 1.7 以英寸-磅为单位的数值应视为标准。括号中给出的值是国际单位制的数学转换，仅供参考，不被视为标准。 1.8 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。 具体警告说明见第节 8. 。 1.9 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 原油和减压渣油以及其他石油馏分的沸点分布的测定为炼油厂的运营提供了重要信息。这些沸点分布提供了关于产品的潜在质量百分比产率的信息。 该测试方法可以提供有用的信息，有助于建立炼油厂的操作条件。所产生的残渣量的知识对于确定精炼过程的经济性是重要的。

1.1 This test method covers the determination of the boiling point distribution and cut point intervals of crude oils and residues by using high temperature gas chromatography. The amount of residue (or sample recovery) is determined using an external standard. 1.2 This test method extends the applicability of simulated distillation to samples that do not elute completely from the chromatographic system. This test method is used to determine the boiling point distribution through a temperature of 720 °C. This temperature corresponds to the elution of n -C 100 . 1.3 This test method is used for the determination of boiling point distribution of crude oils. This test method uses capillary columns with thin films, which results in the incomplete separation of C 4 -C 8 in the presence of large amounts of carbon disulfide, and thus yields an unreliable boiling point distribution corresponding to this elution interval. In addition, quenching of the response of the detector employed to hydrocarbons eluting during carbon disulfide elution, results in unreliable quantitative analysis of the boiling distribution in the C 4 -C 8 region. Since the detector does not quantitatively measure the carbon disulfide, its subtraction from the sample using a solvent-only injection and corrections to this region via quenching factors, results in an approximate determination of the net chromatographic area. A separate, higher resolution gas chromatograph (GC) analysis of the light end portion of the sample may be necessary in order to obtain a more accurate description of the boiling point curve in the interval in question as described in Test Method D7900 (see Appendix X1 ). 1.4 This test method is also designed to obtain the boiling point distribution of other incompletely eluting samples such as atmospheric residues, vacuum residues, etc., that are characterized by the fact that the sample components are resolved from the solvent. 1.5 A correlation between boiling range distribution results from Test Method D2892 , and the weight percentage data determined via this method, is presented in Appendix X2 . 1.6 This test method is not applicable for the analysis of materials containing a heterogeneous component such as polyesters and polyolefins. 1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.8 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. Specific warning statements are given in Section 8 . 1.9 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 determination of the boiling point distribution of crude oils and vacuum residues, as well as other petroleum fractions, yields important information for refinery operation. These boiling point distributions provide information as to the potential mass percent yield of products. This test method may provide useful information that can aid in establishing operational conditions in the refinery. Knowledge of the amount of residue produced is important in determining the economics of the refining process.
