Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 28 May 2018 - 08 June 2018
- 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))
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- DIN 51794 (Testing of mineral oil hydrocarbons - Determination of ignition temperature)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Auto-ignition temperature:
- 245 °C
- Atm. press.:
- >= 1 013 - <= 1 019 hPa
- Conclusions:
- The auto flammability of the test item is 245ºC according to EU method A.15 criteria.
- Executive summary:
The determination of the auto flammability of the test item was performed according to EU Method A.15 (GLP study). About 200 mL of sample are introduce into an opened Erlenmeyer’s flask. Series of ignition trials were performed by changing the temperature of the chamber walls and amount of a sample, and searching for the lowest temperature in which an ignition appears. The auto flammability of the test item was determined to be 245ºC with atmospheric pressure ranging from 1013 to 1019 hPa.

Additional information
Key study: The determination of the auto flammability of
the test item was performed according to EU Method A.15 (GLP study).
About 200 mLof sampleare introduce into an opened Erlenmeyer’s
flask. Series of ignition trials were performed by changing the
temperature of the chamber walls and amount of a sample, and searching
for the lowest temperature in which an ignition appears. The auto
flammability of the test item was determined to be 245ºC with
atmospheric pressure ranging from 1013 to 1019 hPa.
