Applicant's summary and conclusion

Conclusions:
The GLP study was performed according to EU method A.15 without deviations and therefore reliability of Klimisch 1 has been assigned. The substance did not undergo spontaneous combustion under the conditions of the test.
Executive summary:

The auto ignition temperature of the test substance was determined in a GLP test according to EU method A.15. The temperature/time-diagram shows a slight endothermic effect at the temperature range from about 145 °C to 180 °C. The basket was empty at the end of the measurement. No exothermic effect can be observed. This result is in accordance with the result of the determination of the melting point. The substance does not undergo spontaneous combustion.
