During the annual proficiency testing program 2013/2014, it was decided to continue the round robin for the analysis of Gasoline in accordance with the most recent version of the specification ASTM D4814. In this interlaboratory study 134 laboratories in 65 different countries have participated. See appendix 3 for the number of participants per country. In this report, the results of the gasoline 2014 proficiency test are presented and discussed. This report is also electronically available through the iis internet site www.iisnl.com. 2 SET UP The Institute for Interlaboratory Studies (iis) in Spijkenisse, the Netherlands, was the organiser of this proficiency test. Sample analyses for fit-for-use and homogeneity testing were subcontracted. In this proficiency test, the participants received, depending on their registration, 2*1 litre bottle euro 95 Gasoline (labelled #14009) and/or 1*1 litre bottle (± 750 mL filled) euro 95 Gasoline (labelled #14010) for DVPE only. Participants were requested to report rounded and unrounded results. The unrounded results were preferably used for statistical evaluation. 2.1 ACCREDITATION The Institute for Interlaboratory Studies in Spijkenisse, the Netherlands, is accredited in agreement with ISO/IEC 17043:2010 (R007), since January 2000, by the Dutch Accreditation Council (Raad voor Accreditatie).

After transferring 500 liter into a 500 liter mixing vessel and homogenisation, 142 amber glass bottles of 1 litre with approx. 800 mL were filled and labelled #14010 “for DVPE only”. The homogeneity of the subsamples #14010 was checked by determination of Dry Vapour Pressure Equivalent in accordance with ASTM D5191 on 7 stratified randomly selected samples. DVPE in psi Sample #14010-1 Sample #14010-2 Sample #14010-3 Sample #14010-4 Sample #14010-5 Sample #14010-6 Sample #14010-7 8.50 8.44 8.44 8.46 8.47 8.44 8.46 Table 1: homogeneity test results of subsamples #14010 From the remaining material in the 500L mixing vessel, 349 amber glass bottles of 1 litre were filled and labelled #14009. The homogeneity of the subsamples #14009 was checked by determination of Density @15°C in accordance with ASTM D4052 on 10 stratified randomly selected samples. Density @ 15°C in kg/m3 Sample #14009-1 Sample #14009-2 Sample #14009-3 Sample #14009-4 Sample #14009-5 Sample #14009-6 Sample #14009-7 Sample #14009-8 Sample #14009-9 Sample #14009-10 749.50 749.51 749.59 749.50 749.49 749.53 749.51 749.53 749.55 749.50 Table 2: homogeneity test results of subsamples #14009 From the above test results, the repeatabilities were calculated and compared with 0.3 times the corresponding reproducibilities in agreement with the procedure of ISO 13528, Annex B2 in the next table: r (sample #14009) r (sample #14010) reference method 0.3 x R (ref. method) Density@ 15 °C in kg/m3 DVPE in psi 0.08 ---ASTM D4052:11 0.57 ---0.059 ASTM D5191:13 0.096 Table 3: repeatabilities of subsamples #14009 and #14010 Gasoline: iis14B01ASTM page 5 of 67 Institute for Interlaboratory Studies Spijkenisse, April 2014 The calculated repeatabilities of the results of homogeneity test for Density and DVPE were less than 0.3 times the reproducibilities of the reference test methods. Therefore, homogeneity of subsamples #14009 and #14010 was assumed. To the participants, depending on their registration, 2*1 litre bottle of sample #14009 and/or 1*1 litre bottle (± 750 mL filled) of sample #14010 were sent on February 5, 2014. 2.5 STABILITY OF THE SAMPLES The stability of Gasoline, packed in the brown glass bottles, was checked. The material was found sufficiently stable for the period of the proficiency test. 2.6 ANALYSIS The participants were requested to determine API Gravity, Aromatics by FIA, Benzene, Copper Strip Corrosion, Doctor Test, Density @ 15°C, Distillation (automated or manual), Existent gum, Lead, Phosphorus, Olefins by FIA, DIPE, Ethanol, ETBE, MTBE, Iso-Butanol, IsoPropanol, TAME, t-Butanol, Methanol, Oxygen, Oxidation Stability, Total Oxygenates, Sulphur, RON and MON on sample #14009. On sample #14010, the participants were requested to determine Total Vapour Pressure and Dry Vapour Pressure (acc. ASTM D5191 and EPA). To get comparable results a detailed report form, on which the units were prescribed as well as some of the required standards and a letter of instructions were prepared and made available for download on the iis website (www.iisnl.com). A SDS and a form to confirm receipt of the samples were added to the sample package. 3 RESULTS During four weeks after sample despatch, the results of the individual laboratories were gathered. The original data are tabulated per determination in appendix 1 of this report. The laboratories are presented by their code numbers. Directly after the deadline, a reminder fax was sent to the laboratories that had not reported results at that moment. Shortly after the deadline, the available results were screened for suspect data. A result was called suspect in case the Huber Elimination Rule (a robust outlier test) found it to be an outlier. The laboratories that produced these suspect data were asked to check the results. Additional or corrected results are used for data analysis and original results are placed under 'Remarks' in the result tables in appendix 1. 3.1 STATISTICS Statistical calculations were performed as described in the report ‘iis Interlaboratory Studies: Protocol for the Organisation, Statistics and Evaluation’ of January 2010 (iis-protocol, version 3.2). For the statistical evaluation the unrounded (when available) figures were used instead of the rounded results. Results reported as ‘< ’ or ‘> ’ were not used in the statistical evaluation. page 6 of 67 Gasoline: iis14B01ASTM Spijkenisse, April 2014 Institute for Interlaboratory Studies First, the normality of the distribution of the various data sets per determination was checked by means of the Lilliefors-test a variant of the Kolmogorov-Smirnov test and by the calculation of skewness and kurtosis. Evaluation of the three normality indicators in combination with the visual evaluation of the graphic Kernel density plot, lead to judgement of the normality being either ‘unknown’, ‘OK’, ‘suspect’ or ‘not OK’. After removal of outliers, this check was repeated. Not all data sets proved to have a normal distribution, in which cases the statistical evaluation of the results should be used with due care. In accordance to ISO 5725 (1986 and 1994) the original results per determination were submitted subsequently to Dixon and Grubbs outlier tests. Outliers are marked by D(0.01) for the Dixon test, by G(0.01) or DG(0.01) for the Grubbs test and by R(0.01) for the Rosner General ESD test (see appendix 4, no.15). Stragglers are marked by D(0.05) for the Dixon test, by G(0.05) or DG(0.05) for the Grubbs test and by R(0.05). Both outliers and stragglers were not included in the calculations of the averages and the standard deviations. For each assigned value, the uncertainty was determined in accordance with ISO13528. Subsequently the calculated uncertainty was evaluated against the respective requirement based on the target reproducibility in accordance with ISO13528. When the uncertainty passed the evaluation, no remarks are made in the report. However, when the uncertainty failed the evaluation it is mentioned in the report and it will have consequences for the evaluation of the test results. Finally, the reproducibilities were calculated from the standard deviations by multiplying them with a factor of 2.8. 3.2 GRAPHICS In order to visualise the data against the reproducibilities from literature, Gauss plots were made, using the sorted data for one determination (see appendix 1). On the Y-axis the reported analysis results are plotted. The corresponding laboratory numbers are under the Xaxis. The straight horizontal line presents the consensus value (a trimmed mean). The four striped lines, parallel to the consensus value line, are the +3s, +2s, -2s and -3s target reproducibility limits of the selected standard. Outliers and other data, which were excluded from the calculations, are represented as a cross. Accepted data are represented as a triangle. Furthermore, Kernel Density Graphs were made. This is a method for producing a smooth density approximation to a set of data that avoids some problems associated with histograms (see appendix 4; nos.13 and 14). Also a normal Gauss curve was projected over the Kernel Density Graph. 3.3 Z-SCORES To evaluate the performance of the participating laboratories the z-scores were calculated. As it was decided to evaluate the performance of the participants in this proficiency test (PT) against the literature requirements, e.g. ASTM reproducibilities, the z-scores were calculated using a target standard deviation. This result was an evaluation independent of the spread of Gasoline: iis14B01ASTM page 7 of 67 Institute for Interlaboratory Studies Spijkenisse, April 2014 this interlaboratory study. The target standard deviation was calculated from the literature reproducibility by division with 2.8. When a laboratory did use a test method with a reproducibility that is significantly different from the reproducibility of the reference test method used in this report, it is strongly advised to recalculate the z-score, while using the reproducibility of the actual test method used, this in order to evaluate whether the reported test result is fit-for-use. The z-scores were calculated in accordance with: z(target) = (result - average of PT) / target standard deviation The z(target) scores are listed in the result tables in appendix 1. Absolute values for z<2 are very common and absolute values for z>3 are very rare. Therefore the usual interpretation of z-scores is as follows: |z| < 1 good 1 < |z| < 2 satisfactory 2 < |z| < 3 questionable 3 < |z| unsatisfactory 4 EVALUATION In this proficiency test problems were encountered with the despatch of the samples. Several laboratories in Brazil, Chile, Costa Rica, Jordan, Malaysia, Niger, Oman, Russia, Sudan, Tanzania and U.S.A. received the samples late or not at all. From the 134 participants, 5 participants did not report any results and 24 participants did report the results after the deadline. Finally 129 laboratories did report 1930 numerical results. Observed were 73 outlying results, which is 3.8%. In proficiency studies, outlier percentages of 3% - 7.5% are quite normal. 4.1 EVALUATION PER TEST In this section, the results are discussed per sample and per test. The methods, which are used by the various laboratories, are taken into account for explaining the observed differences where possible and applicable. These methods are also in the tables together with the reported data. The abbreviations, used in these tables, are listed in appendix 4. In the iis PT reports, ASTM methods are referred to with a number (e.g. D2086) and an added designation for the year that the method was adopted or revised (e.g. D2086-08). If applicable, a designation in parentheses is added to designate the year of reapproval (e.g. D2086-08 (2013)). In the results tables of Appendix 1 only the method number and year of adoption or revision will be used. Not all data sets proved to have a normal distribution. Not normal (or suspect) distributions were found for sample #14009: Benzene, Density, Distillation Automated (70% evap and page 8 of 67 Gasoline: iis14B01ASTM Spijkenisse, April 2014 Institute for Interlaboratory Studies 90% evap), Distillation Manual (IBP), Ethanol, Other Oxygenates (ETBE, IPA, MeOH), Sulphur, DVPE (acc. to EPA). In these cases, the statistical evaluation should be used with care. Remarkably a number of laboratories reported to have used EN22854 for several components. The correct method description is ISO22854 or EN-ISO-22854. ISO developed the standard ISO22854 and this standard was later adopted by the Comité Européen de Normalisation (CEN) to give EN-ISO-22854. API Gravity: This determination was not problematic. Three statistical outliers were observed. However, the calculated reproducibility after rejection of the statistical outliers is in good agreement with the requirements of ASTM D4052:11. Benzene: This determination was not problematic. One statistical outlier was observed. The calculated reproducibility after rejection of the statistical outlier is in agreement with the requirements of ASTM D3606:10. Copper strip: No problems have been observed. All participants agreed on classification 1. Density @ 15°C: This determination was problematic for a number of laboraties. Four statistical outliers were observed. However, the calculated reproducibility after rejection of the statistical outliers is in good agreement with the requirements of ASTM D4052:11. Distillation The automated mode determination was not problematic. In total ten statistical outliers were observed. The calculated reproducibilities after rejection of the statistical outliers are all in agreement with the requirements of ASTM D86:12 for the automated mode, except for 50% evaporated. The manual mode determination was not problematic. In total thirteen statistical outliers were observed. The calculated reproducibilities after rejection of the statistical outliers are all in agreement with the requirements of ASTM D86:12 for the manual mode. Doctor Test: No analytical problems have been observed, all participants agreed on the absence of Mercaptans. Existent Gum: This determination was not problematic. Two statistical outliers were observed. However, the calculated reproducibility after rejection of the statistical outliers is in good agreement with the requirements of ASTM D381:12. Olefins by FIA: This determination was not problematic. Two statistical outliers were observed. The calculated reproducibility after rejection of the statistical outliers is in agreement with the requirements of ASTM D1319:10. When the ASTM D1319/EN15553 results were evaluated separately, the calculated Gasoline: iis14B01ASTM page 9 of 67 Institute for Interlaboratory Studies Spijkenisse, April 2014 reproducibility is larger but still in agreement with the requirements of ASTM D1319:10. Remarkably 5 laboratories reported to have used a GC method. Aromatics by FIA: This determination was problematic. One statistical outlier was observed. However, the calculated reproducibility after rejection of the statistical outlier is not in agreement with the requirements of ASTM D1319:10. When the ASTM D1319:10/EN15553 results were evaluated separately, the calculated reproducibility somewhat smaller but still not in agreement with the requirements of ASTM D1319:10. Remarkably 5 laboratories reported to have used a GC method. Lead: The consensus value of the group was below the application range (2.5 – 25 mg/L) of ASTM D3237:12. Therefore, no significant conclusions were drawn. Phosphorus: The consensus value of the group was below the application range (0.20 - 40 mg/L) of ASTM D3231:13. Therefore, no significant conclusions were drawn. Oxidation stability: The majority of the laboratories agreed that the Oxidation Stability is >360 (or even >900) minutes. Ethanol: This determination was problematic for a number of laboratories. Five statistical outliers were observed. However, the calculated reproducibility after rejection of the statistical outliers is in agreement with the requirements of ASTM D4815:13. MTBE: This determination was problematic. Four statistical outliers were observed. The calculated reproducibility after rejection of the statistical outliers is not in agreement with the requirements of ASTM D4815:13. The large spread may (partly) be explained by the variety of test methods used. Sixteen laboratories reported to have used to ASTM D4815 and fourteen laboratories reported to have used to EN13132, both calculated reproducibilities are not in agreement with the respective requirements of ASTM D4815 and EN13132. Sixteen laboratories reported to have used to ISO22854, the calculated reproducibility for these test results is in agreement with the less strict requirements for ISO22854. Other Oxygenates: The concentrations of the other oxygenates were all near or below the detection limit of the method used and most of the participants reported a “less then” result. Therefore, no significant conclusions were drawn. In total five observed false positive test results were observed, two for TAME and three for ETBE. page 10 of 67 Gasoline: iis14B01ASTM Spijkenisse, April 2014 Institute for Interlaboratory Studies Total Oxygenates: This determination was problematic for number of laboratories. Five statistical outliers were observed. However, the calculated reproducibility after rejection of the statistical outliers is in full agreement with the estimated requirements of ASTM D4815:13 based on reproducibilities of Ethanol and MTBE. Oxygen content: This determination was not problematic. Three statistical outliers were observed. However, the calculated reproducibility after rejection of the statistical outliers is in agreement with the requirements of ASTM D5599:00(2010) and D4815:13. Sulphur: This determination was problematic for number of laboratories. Seven statistical outliers were observed. However, the calculated reproducibility after rejection of the statistical outliers is in full agreement with the requirements of ASTM D5453:12. RON: This determination was not problematic. Three statistical outliers were observed. However, the calculated reproducibility after rejection of the statistical outliers is in agreement with the requirements of ASTM D2699:13a. MON: This determination was not problematic. Only one statistical outlier was observed. The calculated reproducibility after rejection of the statistical outlier is in full agreement with the requirements of ASTM D2700:13b. TVP: This determination was not problematic. Three statistical outliers were observed. However, the calculated reproducibility, after rejection of the statistical outliers, is in agreement with the requirements of ASTM D5191:13. DVPE: The conversion of the measured Total Vapour Pressure to the corresponding Dry Vapour Pressure Equivalent (DVPE) as described in ASTM D5191:13 and to the U.S. EPA guidelines (40 CFR Part 80, App. E, Method 3), showed in in total 4 statistical outliers. Both calculated reproducibilities after rejection of the statistical outliers are in agreement with the respective requirements of ASTM D5191:13 and EPA guidelines. Gasoline: iis14B01ASTM page 11 of 67 Institute for Interlaboratory Studies 4.2 Spijkenisse, April 2014 PERFORMANCE EVALUATION FOR THE GROUP OF LABORATORIES A comparison has been made between the reproducibility as declared by the relevant standard and the reproducibility as found for the group of participating laboratories. The average results of sample #14009 and #14010, calculated reproducibilities and reproducibilities, derived from literature standards (in casu ASTM standards) are compared in the next table.
