1.1本试验方法包括测定538°C（1000°F）下无水原油的沸腾范围分布。在538°C以上沸腾的材料被报告为残渣。本试验方法适用于可溶解在溶剂中的整个原油样品，以允许通过微量比色法进行取样。 1.2以国际单位制表示的数值应视为标准。以英寸-磅为单位的数值仅供参考。 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和健康实践，并确定监管限制的适用性。 7.2、7.5、7.6、7.7和7.9中给出了具体的预防说明。 ====意义和用途====== 沸点分布的测定是原油分析的基本要求。该信息可用于估计炼油厂产量，并与其他信息一起评估使用一种特定原油与另一种原油的经济性。 本试验方法所得结果与试验方法D 2892所得结果相同 . （参见 附录X1 .) 该测试方法比测试方法D 2892快 当只有少量样品可用时，可以使用。此外，该测试方法得出的结果高达538 ° C，而试验方法D 2892 限400人 ° C

1.1 This test method covers the determination of the boiling range distribution of water-free crude petroleum through 538°C (1000°F). Material boiling above 538°C is reported as residue. This test method is applicable to whole crude samples, that can be solubilized in a solvent to permit sampling by means of a microsyringe. 1.2 The values stated in SI units are to be regarded as the standard. The values stated in inch-pound units are for information only. 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 and health practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in 7.2, 7.5, 7.6, 7.7, and 7.9. ====== Significance And Use ====== The determination of the boiling range distribution is an essential requirement in crude oil assay. This information can be used to estimate refinery yields and, along with other information, to evaluate the economics of using one particular crude as opposed to another. Results obtained by this test method are equivalent to those obtained from Test Method D 2892 . (See Appendix X1 .) This test method is faster than Test Method D 2892 and can be used when only small volumes of samples are available. Also, this test method gives results up to 538 ° C while Test Method D 2892 is limited to 400 ° C.
