No self-ignition was recorede up to the end temperature of 403 °C.
Individual results
The test item was a solidified melt. Therefore it was liquefied at 80 °C before the measurements.
Preliminary test
Table 1 shows the results of the preliminary tests. Temperatures where self-ignition was detected are marked with +; temperatures where no self-ignition was detected are marked within the below table. The amount of test item tested at each measurement is indicated as numbers of portions (i.e. drops).

The lowest self-ignition temperature of the test item was determined to be 473 °C in the preliminary test.
Main tests
In Table 2 to Table 5 the results of the main test are shown. Temperatures where self-ignition was detected are marked with +; temperatures where no self-ignition was detected are marked within the below table. The amount of test item tested at each measurement is indicated as numbers of portions (i.e. drops).

The lowest auto-ignition temperature of the test item was determined to be 432 °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 430 °C.
Description of key information
The test substance (pure) is classified within the definition of the Directive as not highly flammable. No self-ignition was recorede up to the end temperature of 403 °C.
The auto-ignition temperature of the test item (technical substance) according to the auto-ignition test conditions in the Method A. 15. was 430 °C.
Key value for chemical safety assessment
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
