- Conclusions:
- The auto-ignition temperature of the test item is 490 °C.
- Executive summary:
The experimetal determination of the auto-ignition temperature of the test item was performed according to standard DIN 51794:2003-05 / EU method A.15 (GLP study). A preliminary study was performed by introducing five drops of sample in the auto ignition temperature apparatus,
increasing the temperature at 50ºC intervals in a first run, and 20ºC intervals in a second run, in order to determine the starting point of the main test. The main test was performed in four runs, first decreasing the temperature at 5ºC intervals, and finally at 2ºC intervals, until the lowest temperature was determined. The auto-ignition temperature of the test item was determined to be 490 °C.

Additional information
The experimetal determination of the auto-ignition temperature of
the test item was performed according to standard DIN 51794:2003-05 / EU
method A.15 (GLP study). A preliminary study was performed by
introducing five drops of sample in the auto ignition temperature
apparatus,
increasing the temperature at 50ºC intervals in a first run, and 20ºC
intervals in a second run, in order to determine the starting point of
the main test. The main test was performed in four runs, first
decreasing the temperature at 5ºC intervals, and finally at 2ºC
intervals, until the lowest temperature was determined.The
auto-ignition temperature of the test item was determined to be 490 °C.
