Preliminary test results
In the preliminary test, 33 injections were performed in a temperature range of 105 to 407 °C. Auto ignitions occurred at 15 temperature points, from 360 to 407 °C.
The lowest auto-ignition temperature was found between 359 °C and 360 °C (corrected value) with a volume of 190 μL. The main test was therefore conducted using this volume.

Applicant's summary and conclusion
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
