Applicant's summary and conclusion

Conclusions:
The auto-ignition temperature of the substance is 264 degrees C
Executive summary:

The auto-ignition temperature of the substance was determined using a method designed to be compatible with EU Method A.15. Varying amounts of the substance were heated in a flask and observed for signs of ignition over a 300 second period until the lowest temperature at which ignition occured was determined.

The auto-ignition temperature of the test substance was determined to be 264 degrees C at atmospheric pressures between 98.00 - 100.45 kPa.
