Applicant's summary and conclusion

Conclusions:
The auto ignition temperature was determined in three independent determinations. A lowest value of the main test of 247 °C was found.
Therefore, the auto-ignition temperature according to EU A.15 (rounded down to a whole multiple of 5 °C) of Naphtha/Light Oil is stated as 245 °C.
