What is PD CEN/TR 15745 - Multidimensional GC for liquid petroleum products about?
Safety is a prime concern when dealing with petroleum products. PD CEN/TR 15745 is a safety standard on liquid petroleum products.
PD CEN/TR 15745, which is a Technical Report, presents the study on the application of EN 14517 to other oxygenates. PD CEN/TR 15745 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.
PD CEN/TR 15745 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. PD CEN/TR 15745 also supports the use of multidimensional chromatography as the method for disputes on oxygenates in EN 228.
Note: For the purposes of PD CEN/TR 15745, the term “% (V/V)” is used to represent the volume fraction.
Who is PD CEN/TR 15745- Multidimensional GC for liquid petroleum products for?

- Quality control personnel
Why should you use PD CEN/TR 15745 - Multidimensional GC for liquid petroleum products?
PD CEN/TR 15745 focuses on oxygenates. Results for other properties (aromatics, olefins, benzene) are listed in the tables of PD CEN/TR 15745.
PD CEN/TR 15745 is about Round Robin that was organized in 2010 to establish a test method to determine the oxygenated components in ethanol automotive fuel (E85). Components such as ethers, C3-C5 alcohols, and ethanol could be made part of an E85 specification.
Four methods were tested:
- EN ISO 22854 modified (with sample dilution)
- EN 1601 modified (with sample dilution)
- Capillary column method (2 columns in series, UNGDA method)
- Capillary column method (2 separate columns, Suedzucker method)
Only the first method with sample dilution had enough participants to derive a precision statement. The dilution step was needed to lower the ethanol content in the sample to values below 20 % (V/V).
PD CEN/TR 15745 helps in determining hydrocarbon types and oxygenates via the multidimensional gas chromatography method and Round Robin research report. This contributes to safety in the industry and also towards research.
