- from 201803-20 to 2018-12-04
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- GLP compliance:

- Key result
- Auto-ignition temperature:
- 315 °C
- Atm. press.:
- >= 997.9 - <= 1 000.1 hPa
- Conclusions:
- The auto-ignition temperature of the test item was determined to be 315 °C.
- Executive summary:
A study was conducted according to Regulation (EC) No 440/2008 method A.15 to determine the auto-ignition temperature of the test item. A preliminary test was carried out to determine the auto-ignition temperature of the test item based on visual inspection. This temperature was used as a starting temperature in the main test. In the main test the auto-ignition temperature of the test item was determined to be 317 °C and rounded down to the nearest multiple of 5 °C, the auto-ignition temperature of the test item was stated to be 315 °C.
Reference
Preliminary Test
5 drops were put into the Erlenmeyer flask at each temperature. The lowest temperature at which an ignition occurred was 330 °C.

Based on results of the main test series, the lowest auto-ignition temperature was 317 °C. The auto-ignition temperature rounded down to the nearest multiple of 5 °C was determined as 315 °C.
Description of key information
The auto-ignition temperature of the the test item was determined to be 315 °C at atmospheric pressure.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 315 °C
