Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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:
- NOV 2009
- 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
- GLP compliance:
- yes (incl. QA statement)
- Remarks:
- Harlan Laboratories Ltd., Derbyshire, UK
- Auto-ignition temperature:
- >= 373 - <= 383 °C
- Atm. press.:
- >= 100.9 - <= 101.18 kPa
- Conclusions:
- auto-ignition temperature: 378 ± 5°C (at 100.90 to 101.18 kPa)
- Executive summary:
The auto-ignition temperature was conducted using EU Method A.15 under GLP conditions.. Aliquots of test material were injected into the flask (heated in a flask heater) using a syringe and the flaks observed for signs of ignition over a 300 second period. The procedure was repeated, varying the sample size, as necessary, until the lowest temperature at which the ignition, if any occurred within 300 seconds of insertion, was determined. The test material has been determined to have an auto-ignition temperature of 378 ± 5°C (at 100.90 to 101.18 kPa).

Description of key information
The auto-ignition temperature was conducted using EU Method A.15 under GLP conditions.. Aliquots of test material were injected into the flask (heated in a flask heater) using a syringe and the flaks observed for signs of ignition over a 300 second period. The procedure was repeated, varying the sample size, as necessary, until the lowest temperature at which the ignition, if any occurred within 300 seconds of insertion, was determined. The test material has been determined to have an auto-ignition temperature of 378 ± 5°C (at 100.90 to 101.18 kPa).
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 378 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
