Conclusions:
The auto flammability of the test item is 425ºC according to EU method A.15 criteria.


Executive summary:

The determination of the auto flammability of the test item was performed according to EU Method A.15 (GLP study). About 200 mL of 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 425ºC with atmospheric pressure ranging from 1015 to 1019 hPa.
