Applicant's summary and conclusion

Conclusions:
The auto-ignition temperature of Guaiacwood oil is 252ºC at an atmospheric pressure of 100.6 to 102.2 kPa.
Executive summary:

The auto-ignition temperature of Guaiacwood oil was determined according to EU Method A.15 using a Carbolite flask heater under GLP. The auto-ignition temperature was found to be 252ºC ± 5ºC at an atmospheric pressure of 100.6 to 102.2 kPa.
