本文件规定了石油产品沸点分布的测定方法。本方法适用于在本文件确定的大气压下最终沸点为538℃或更低的石油产品和馏分。本文件不适用于汽油样品或汽油成分。该方法仅限于沸点范围大于55℃且蒸汽压力足够低以允许在环境温度下取样的产品。文件描述了两个过程。a） 程序a允许选择更多的色谱柱和分析条件，例如填充柱和毛细管柱，以及除了火焰离子化检测器之外的热导检测器。分析时间从14分钟到60分钟不等。b） 程序b仅限于三个毛细管柱，不需要样品稀释。分析时间缩短到8分钟左右。两种方法均已成功应用于脂肪酸甲酯（FAME）含量高达20%（体积分数）的样品。注:在本文件中，术语“%（质量分数）”和“%（体积分数）”用于表示材料的质量分数（μ）、体积分数（φ）。

This document specifies a method for the determination of the boiling range distribution of petroleum products. The method is applicable to petroleum products and fractions with a final boiling point of 538 °C or lower at atmospheric pressure as determined by this document. This document does not apply to gasoline samples or gasoline components. The method is limited to products having a boiling range greater than 55 °C and having a vapour pressure sufficiently low to permit sampling at ambient temperature. The document describes two procedures. a) Procedure A allows a larger selection of columns and analysis conditions, such as packed and capillary columns as well as a thermal conductivity detector in addition to the flame ionization detector. Analysis times range from 14 min to 60 min. b) Procedure B is restricted to only three capillary columns and requires no sample dilution. The analysis time is reduced to about 8 min. Both procedures have been successfully applied to samples containing fatty acid methyl esters (FAME) up to 20 % (volume fraction). NOTE For the purposes of this document, the terms "% (mass fraction)" and "% (volume fraction)" are used to represent the mass fraction (µ), the volume fraction (φ) of a material.
