本文介绍了用毛细管气相色谱法测定石油产品沸点分布的方法。本标准适用于原油。可以确定沸腾范围分布和C100或C120的回收率。 描述了两个过程:单分析模式和双分析模式。每种方法的基础是附录A中所述的计算程序。 程序A（或单一分析模式）确定单一分析中C100或C120的沸腾范围。 程序B（或双重分析模式）将程序A与沸点分布（从C1到C9）结合起来，使用EN 15199-4规定的详细碳氢化合物分析（DHA）。两种分析的结果合并成一个沸点分布。 注1:对于程序B获得的综合结果，没有具体的精度说明。对于程序B的沸腾范围分布精度，程序A和EN 15199-4的精度说明适用。合并后的结果尚未确定精度。 注2:在本文件中，术语“%（m/m）”和“%（V/V）”分别表示材料的质量分数μ和体积分数φ。 警告-使用本文件可能涉及危险材料、操作和设备。本文件并非旨在解决与其使用相关的所有安全问题。本标准的使用者有责任建立适当的安全和健康实践，并在使用前确定监管限制的适用性。

This document describes a method for the determination of the boiling range distribution of petroleum products by capillary gas chromatography using flame ionization detection. The standard is applicable to crude oils. The boiling range distribution and recovery to C100 or C120 can be determined. Two procedures are described: single and dual analysis mode. The basis of each is the calculation procedure as described in Annex A. Procedure A (or Single analysis mode) determines the boiling range through C100 or C120 in a single analysis. Procedure B (or Dual analysis mode) combines procedure A with the boiling point distribution from C1 up to C9 using the Detailed Hydrocarbon Analysis (DHA) according EN 15199-4. The results of both analyses are merged into one boiling point distribution. NOTE 1 There is no specific precision statement for the combined results obtained by procedure B. For the precision of the boiling range distribution according to procedure B the precision statements of procedure A and EN 15199-4 apply. No precision has been determined for the results after merging. NOTE 2 For the purpose of this document, the terms "% (m/m)" and "% (V/V)" are used to represent the mass fraction, μ, and the volume fraction, φ, of a material respectively. WARNING - Use of this document may involve hazardous materials, operations and equipment. This document does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
