16、 In 2004, the company AC Analytical Controls1)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

17、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 info

18、rmation and instructions to improve the performance. The intention was to get a precision statement for oxygenates that were not included in EN 14517 2, but that are listed in EN 228. Besides this, the performance for other properties (aromatics, olefins, benzene) has been determined. More informati

19、on 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 o

20、n the other properties. The precision data obtained from this program were used to develop the EN ISO 22854 method which was published in 2008 3. In 2010 another Round Robin was organized to establish a test method to determine the oxygenated components in ethanol automotive fuel (E85). Components s

21、uch as ethers, C3-C5 alcohols and ethanol could be made part of an E85 specification. Four methods were tested: A. EN ISO 22854 modified (with sample dilution) B. EN 1601 modified (with sample dilution) C. Capillary column method (2 columns in series, UNGDA method) D. Capillary column method (2 sepa

22、rate columns, Suedzucker method) Only method A 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). The Round Robin was carried out by TC 19/WG 9 and the results were evaluate

23、d conform EN ISO 4259. As methods B, C and D did not get enough participants a 2nd ILS was carried out to see if more data could be obtained for these methods. The details of these Round Robin Tests are added as Appendix A and B to this Research Report. 1) Postal address: AC Analytical Controls, Inn

PD CEN/TR 15745:2015CEN/TR 15745:2015 (E) 6 1 Scope This Technical Report presents the study on the application of EN 14517 2 to other oxygenates. This report supports an extension of the scope of the method, which has been explicitly

25、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 3. This Technical 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 Europea

26、n Fuels Directive. This Technical Report should also support the use of multidimensional chromatography as the method for disputes on oxygenates in EN 228 1.
