Comments: atmospheric pressure: 1006- 1009 hPa

Conclusions:

The auto-ignition temperature of the test item is 385ºC under atmospheric pressure of 1006-1009 hPa.

Executive summary:

The auto-ignition temperature of the test item was determined according to EU Method A.15 "Auto-ignition temperature (liquids and gases)", under GLP conditions. The temperature of the auto-ignition was established at first with a rough approximation in a preliminary test. About 200 mLof sampleare introduce into an opened Erlenmeyer’s flask. Series of ignition trials were performed by changing the temperature of the chamber walls and amount of a sample, and searching for the lowest temperature in which an ignition appears. The auto flammability of the test item was determined to be 385ºC with atmospheric pressure ranging from 1006 to 1009 hPa.
