Scope
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.
