Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Auto flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- guideline study with acceptable restrictions
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- DIN 51794 (Testing of mineral oil hydrocarbons - Determination of ignition temperature)
- GLP compliance:
- no
- Other quality assurance:
- ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories)
- Key result
- Auto-ignition temperature:
- 475 °C
- Atm. press.:
- 1 009 hPa
- Conclusions:
- The auto ignition temperature of the test substance is 475 °C measured at 1009 hPa.
- Executive summary:
The test was performed as stipulated in EC Test Procedure A.15 'Auto-ignition temperature (liquids and gases)' (DIN 51794 - Determining the ignition temperature of petroleum products).
A small portion of the flammable substance under test was introduced into an open conical flask (Erlenmeyer flask). The flask was heated in an electric furnace and it was observed whether ignition takes place at the prevailing temperature. Finally, any vaporizable components left in the flask were blown out with air. The lowest result of an ignition was found in the main tests at 480 °C.Bearing in mind the significance of the ignition temperature for risk assessment, the result is not reported as the mean, but as the lowest value, where no ignition occurs.
Thus, the auto-ignition temperature of the test substance was determined as 475 °C at 1009 hPa.

Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 475 °C
Additional information
No difference is to be expected between the auto-ignition temperature at 1009 hPa and 1013 hPa.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
