This standard BS EN ISO 3924:2019 Petroleum products. Determination of boiling range distribution. Gas chromatography method is classified in these ICS categories:

• 75.080 Petroleum products in general

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 538Ã?Æ?ââ?¬Å¡Ã?â??Ã? Ã?Æ?ââ?¬Å¡Ã?â??Ã?°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 55Ã?Æ?ââ?¬Å¡Ã?â??Ã? Ã?Æ?ââ?¬Å¡Ã?â??Ã?°C and having a vapour pressure sufficiently low to permit sampling at ambient temperature.

The document describes two procedures.

1. ProcedureÃ?Æ?ââ?¬Å¡Ã?â??Ã? 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 14Ã?Æ?ââ?¬Å¡Ã?â??Ã? min to 60Ã?Æ?ââ?¬Å¡Ã?â??Ã? min.

2. ProcedureÃ?Æ?ââ?¬Å¡Ã?â??Ã? B is restricted to only three capillary columns and requires no sample dilution. The analysis time is reduced to about 8Ã?Æ?ââ?¬Å¡Ã?â??Ã? min.

Both procedures have been successfully applied to samples containing fatty acid methyl esters (FAME) up to 20Ã?Æ?ââ?¬Å¡Ã?â??Ã? %Ã?Æ?ââ?¬Å¡Ã?â??Ã? (volume fraction).
