Conclusions:

The autoignition temperature of the test item has been determined to be 419°C.
This parameter/method is not relevant for classification, however the information is useful regarding potential additional fire hazard. No particular hazard is anticipated in normal conditions of storage.

Executive summary:

The study was performed in order to determine the auto-ignition temperature of test item according to EU A.15 guideline.

The auto-ignition temperature of test item was determined to be 419°C. This value was determined using 200 μl of test substance at 101.4 kPa.

Description of key information
