- Key result
- Auto-ignition temperature:
- 360 °C
- Atm. press.:
- 101 325 Pa
- Conclusions:
- The auto-ignition temperature of the test item was determined to be 360 °C at atmospheric pressure.
- Executive summary:
A study was conducted according to Regulation (EC) No 440/2008 Part A.15 and DIN 51794 (2003) to determine the auto-ignition temperature of the test substance. In a preliminary test the approximate auto-ignition temperature was determined. For the main test three test series were conducted. The temperature determined in the preliminary test was used as starting point for the main test. The temperature was varied in steps of 2 °C until no ignition was observed. According to criteria laid down in Regulation EC No. 440/2008 method A.15 and DIN 51794 the auto-ignition temperature is the lowest value rounded down to a whole multiple of 5 °C. Therefore, the auto-ignition temperature was determined to be 360 °C at 101325 Pa.
Reference
Three replicate main tests were performed under atmospheric pressure.
The following lowest values were recorded:

362 |
8 |
3 |
362 |

Difference between the lowest values of the main studies was less than 20 K, thus, the validity criterion was fulfilled.
The auto-ignition temperature is the lowest value from the lowest values measured during the Main Test, rounded down to the nearest multiple of 5 °C.
The lowest value of the auto-ignition temperature was 362 °C. This value was rounded off, thus, the auto-ignition temperature of the test item is 360 °C determined as in DIN 51794.
Description of key information
The auto-ignition temperature of the test item was determined to be 360 °C at atmospheric pressure.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 360 °C
