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:
- 20 September 2012
- 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
- Qualifier:
- according to guideline
- Guideline:
- other: DIN Guide 51794: "Determining the Ignition Temperature of Petroleum Products" (2003)
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: IEC standard 79-4: "Electrical Apparatus for Explosive Gas Atmospheres, Part 4, Method of Test for Ignition Temperature" (1975)
- Deviations:
- no
- GLP compliance:
- yes
- Auto-ignition temperature:
- 225 °C
- Atm. press.:
- 1 022.1 hPa
- Remarks on result:
- other: The lowest temperature at which ignition occurred was 228°C. This temperature was rounded off to the nearest multiple of 5°C giving the auto-ignition temperature of the substance.
- Conclusions:
- The auto-ignition temperature of the substance was determined to be 225°C at 1022.1 hPa using a commercially available auto-ignition temperature apparatus. The test was performed in accordance with EC A.15, DIN 51794 and IEC 79-4 and according to the principles of GLP.
