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:
- Experimental start: 14 January 2016, Experimental end data: 22 February 2016
- 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:
- yes
- Remarks:
- Using 5 °C increments rather than 2 °C increments as specified in guideline
- GLP compliance:
- yes
- Key result
- Auto-ignition temperature:
- 540 °C
- Atm. press.:
- >= 745 - <= 769 mm Hg
- Conclusions:
- In a relevant and conclusive study, the auto-ignition temperature (AIT) of the test substance was found to be 540 ± 25 °C.
- Executive summary:
The auto-ignition temperature of the test substance was studied under GLP in accordance with IEC 60079-20-1, Section 7, “Method of Test for Auto-Ignition Temperature”, but with 5 °C temperature increments rather than the specified 2°C increments. The experiment is considered relevant, adequate and conclusive.
The auto-ignition temperature of the test substance is 540 ± 25 °C.
