Petroleum products - Determination of boiling range distribution - Gas chromatography method

PUBLISH DATE 2019
ISO 3924:2019

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 ยฐC 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 ยฐC 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 (ยต), the volume fraction (ฯ†) of a material.
