- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- from 2020-04-30 to 2020-05-06
- 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))
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Auto-ignition temperature:
- 395 °C
- Atm. press.:
- >= 991 - <= 1 006.7 hPa
- Conclusions:
- The test item has an auto-ignition temperature of 395 °C.
- Executive summary:
A study was conducted according to theRegulation (EC) No 440/2008 Method A.15.Auto-Ignition Temperature (Liquids and Gases) and DIN 51794 (2003): Determination of Ignition Temperature. The main test was started at the lowest auto-ignition temperature found in the preliminary test and the temperature was then decreased in intervals of 1 – 3 K. This was repeated until no ignition was observed. The auto-ignition temperature of the test item was found to be 395 °C. This value was the lowest auto-ignition temperature of three independent measurements rounded down to the nearest multiple of 5 °C.
