Reference
Preliminary test
The following table shows the results of the preliminary test. Temperatures where auto-ignition was detected are marked with +; temperatures where no auto-ignition was detected are marked with - in the table below. The amount of test item tested at each measurement is indicated as numbers of portions (i.e. drops). The results are summarized in Table.

The lowest auto-ignition temperature of the test item was determined to be 251 °C in the main test. Due to safety reasons and according to the guidelines the lowest measured temperature at which an ignition was observed was rounded to the next lower number divisible by 5, giving a value of 250 °C.
Final results
The auto-ignition temperature of the test item according to the auto-ignition test conditions in the sense of the European Commission Regulation (EC) No. 440/2008, Method A.15. was 250 °C.
Description of key information
