The ignition delay time of two JET-A samples obtained at random at two locations (Haifa and Stuttgart) have been investigated in parallel, by two groups of researchers. The experiments carried out in two different shock tube devices covered a temperature range of 1100 to 1900 K at pressures between 2.4 and 6 bar. The four sets of experiments consisting of almost 400 shocks are analyzed, statistically evaluated, and compared with ignition delay experiments for decane. Computer simulation of different surrogate fuel models among them: (i) pure n-decane, (ii) a mixture of 70% n-decane, 15% benzene, and 15% toluene - are compared to experimental data. It was found that all measured ignition delay time data can be represented by a single statistical fit. Furthermore, predictions by using pure n-decane as the surrogate fuel match the statistical fit obtained for all the experiments, and explicitly the Stuttgart experiments. The surrogate including n-decane, benzene and toluene showed very good reproducibility of the Haifa experiments and some of the Stuttgart experiment, but were not able to reproduce the very low concentration experiments run at Stuttgart.
