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.
