Room temperature:    21.0 to 22.6 °C

Due to a failure in the instrument used to record the atmospheric pressure, the atmospheric pressure was not recorded. A review of historical atmospheric pressure data over a twelve month period shows the atmospheric pressure as 95.79 to 103.93 kPa at Harlan Laboratories Ltd, Shardlow, UK.

Applicant's summary and conclusion

Conclusions:
The auto-ignition temperature of Cassia oil is 416ºC.
Executive summary:

The auto-ignition temperature of Cassia oil was investigated according to EU Method A.15 under GLP. The auto-ignition temperature was found to be 416ºC.
