- Executive summary:
A GLP study was conducted to determine the auto flammability of dimethyloctadiene according to EU Method A.15. In the preliminary test, strong fuming and sizzle were observed at temperatures above 270 °C at 98998 Pa. In the main test, auto ignition temperatures during test 1, 2 and 3 were observed to be 280, 285 and 285 °C at 99049, 98936 and 99729 Pa, respectively.
Under the test conditions, the auto ignition temperature of dimethyloctadiene was determined to be 280 °C.
Reference
Preliminary test: Strong fuming and sizzle was observed at temperatures above 270 °C. At the highest temperature, one pop (taken as sign of ignition) could be perceived. Atmospheric pressure during the pre-test was 98998.
