- Key result
- Auto-ignition temperature:
- 400 °C
- Atm. press.:
- >= 994.6 - <= 1 001.1 hPa
- Conclusions:
- Under the conditions of this study, the auto ignition temperature of the test material was 400 °C.
- Executive summary:
The auto ignition temperature of the test material was determined in accordance with the standardised guidelines EU Method A.15, DIN 51794 and DIN EN 14522, under GLP conditions.
In the preliminary test, the lowest temperature at which an ignition occurred was 422 °C. The main test was started at the lowest auto-ignition temperature found in the preliminary test and the temperature then decreased in intervals of 2 - 5 K. This was repeated until no ignition was observed. At this temperature the number of drops of test material added to the Erlenmeyer flask was varied (1 – 10 drops). Further tests are carried out by variation of temperature and number of drops in the range where the test material ignites and just not ignites.
Under the conditions of this study, the auto ignition temperature of the test material was 400 °C.
Reference
Preliminary Test
- An approximate value of the ignition temperature of the test material was first determined by a preliminary test. 5 drops were put into the Erlenmeyer flask at each temperature.
- At atmospheric pressure (1002.5 hPa) the lowest temperature at which an ignition occurred was 422 °C.
Main Test
- In test series 1 (atmospheric pressure 999.6 – 1001.1 hPa), the lowest temperature of an ignition was 409 °C and the highest temperature without an ignition was 407 °C.
- In test series 2 (atmospheric pressure 994.6 – 995.1 hPa), the lowest temperature of an ignition was 407 °C and the highest temperature without an ignition was 404 °C.
- In test series 3 (atmospheric pressure 995.9 hPa), the lowest temperature of an ignition was 404 °C and the highest temperature without an ignition was 401 °C.
- Based on results of the main test series, the lowest auto-ignition temperature was 404 °C.
- Regulation EC No. 440/2008 and DIN 51794: The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 400 °C.
- For information: DIN EN 14522: The auto-ignition temperature reduced by 1.5 % and rounded to the nearest integer temperature was determined as 398 °C.
- According to DIN EN 13463-1 the test material has to be assigned to temperature class T2.
Description of key information

Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 400 °C
Additional information
The auto ignition temperature of the test material was determined in accordance with the standardised guidelines EU Method A.15, DIN 51794 and DIN EN 14522, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
In the preliminary test, the lowest temperature at which an ignition occurred was 422 °C. The main test was started at the lowest auto-ignition temperature found in the preliminary test and the temperature then decreased in intervals of 2 - 5 K. This was repeated until no ignition was observed. At this temperature the number of drops of test material added to the Erlenmeyer flask was varied (1 – 10 drops). Further tests are carried out by variation of temperature and number of drops in the range where the test material ignites and just not ignites.
Under the conditions of this study, the auto ignition temperature of the test material was 400 °C.
