Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 24 September 2014 to 05 October 2014
- 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:
- 200 °C
- Atm. press.:
- >= 100.8 - <= 101.7 kPa
- Conclusions:
- Under the conditions of this study, the test material has been determined to have an auto-ignition temperature of 200 ± 5 °C.
- Executive summary:
The auto-ignition temperature of the test material was investigated in accordance with the standardised guideline EU Method A.15, under GLP conditions.
The test flask was heated in a flask heater. Aliquots of test material (tested as received) were injected into the flask using a syringe and the flask observed for signs of ignition over a 300 second period. This procedure was repeated, varying the sample size, as necessary, until the lowest temperature at which ignition, if any, occurred within 300 seconds of insertion, was determined.
Under the conditions of this study, the test material has been determined to have an auto-ignition temperature of 200 ± 5 °C.

Description of key information
Under the conditions of this study, the test material has been determined to have an auto-ignition temperature of 200 ± 5 °C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 200 °C
Additional information
The auto-ignition temperature of the test material was investigated in accordance with the standardised guideline EU Method A.15, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
The test flask was heated in a flask heater. Aliquots of test material (tested as received) were injected into the flask using a syringe and the flask observed for signs of ignition over a 300 second period. This procedure was repeated, varying the sample size, as necessary, until the lowest temperature at which ignition, if any, occurred within 300 seconds of insertion, was determined.
Under the conditions of this study, the test material has been determined to have an auto-ignition temperature of 200 ± 5 °C.
