Introduction
1
In 2004, the company AC Analytical Controls conducted a Performance Monitoring Program on the AC
Reformulyzer™. This is a kind of crosscheck program where customers analyse samples distributed by the
company and then report the analysis results. The company checks the analytical performance of the
instruments, keeping in mind the possible analytical errors that can occur. Because raw data are reported
(chromatogram and data for each carbon number/group), a detailed review can be made. The company
informs a customer when the instrument performance is inadequate and where possible provides information
and instructions to improve the performance.
The intention was to get a precision statement for oxygenates that were not included in EN 14517, but that are
listed in EN 228. Besides this, the performance for other properties (aromatics, olefins, benzene) has been
determined.
More information on the review of the data is available from the monitoring, but this technical report focuses
on oxygenates. Results for other properties (aromatics, olefins, benzene) are listed in the tables but are not
discussed in detail here. Also the evaluation for outliers is done on oxygenates only, not on the other
properties.

1 Scope
This Technical Report presents the study on the application of EN 14517 to other oxygenates. This report
supports an extension of the scope of the method, which has been explicitly requested by ISO/TC 28 at the
time of revision of EN 14517 and was agreed to result in the parallel Standard EN ISO 22854.
This report is published as background information to judge the approval of the use of the method for the
determination of all oxygenates as mentioned in the European Fuels Directive. Next, this report should
support the use of multidimensional chromatography as the method for disputes on oxygenates in EN 228.
NOTE For the purposes of this document, the term “% (V/V)” is used to represent the volume fraction.
