Applicant's summary and conclusion

Conclusions:

The test material has been determined to have an auto-ignition temperature of 384 ± 5°C.

Executive summary:

Method: The auto-ignition temperature was determined by heating aliquots of the test material in a flask and observing for any signs of ignition. Testing was conducted using Method A15 Auto- Ignition Temperature (Liquids and Gases) of Council Regulation (EC) No 440/2008 of 30 May 2008. Conclusion: The test material has been determined to have an auto-ignition temperature of 384 ± 5°C.
