- Executive summary:
The auto-ignition temperature of the test substance was determined according to EU A.15 / DIN 51794 using a commercially available auto-ignition temperature apparatus (Chilworth Technology, Southampton, UK). The auto-ignition temperature of the test substance is 350 °C at 1020.3-1025.5 hPa.
Reference
Preliminary test:
The estimated auto-ignition temperature was 380 °C.
Main study:
The results of the main study on the determination of the auto-ignition temperature of the test substance are given in the table below.
Ignition of the test substance within 5 minutes after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was <20 °C. According to the guidelines, no further testing was required.
The lowest temperature at which ignition of the test substance occurred was 354 °C. This temperature was rounded off to the nearest multiple of 5 giving an auto-ignition temperature of the test substance of 350 °C.
