Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Study period:
- 2012-03-01 to 2012-03-26
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised guideline. Purity of the test substance is specified (with certificate of analysis). Minor restriction is not considered to be significant. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- BS-4056 (Method of test for ignition temperature of gases and vapours)
- Version / remarks:
- 1966
- GLP compliance:
- yes (incl. QA statement)
- Auto-ignition temperature:
- 256 °C
- Atm. press.:
- 1 027 mBar
- Conclusions:
- This parameter/method is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard. No particular hazard is anticipated in normal conditions of storage.
- Executive summary:
The auto-ignition temperature of the test substance was measured under GLP according to BS 4056 standard (listed in EU A15 guideline).
The test material was injected into a heated flask, until the lowest temperature at which ignition occurs was determined. The relevant parameters (volume, time lag, atmospheric pressure) were recorded for the final result.
The test material has been determined to have an auto-ignition temperature of 256 °C.
- Endpoint:
- auto-ignition temperature (liquids)
- Type of information:
- read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Justification for type of information:
- Please refer to the RAAF document in IU section 13 for detailed justification.
- Reason / purpose for cross-reference:
- read-across source
- Key result
- Auto-ignition temperature:
- ca. 256 °C
- Atm. press.:
- 1 027 mBar
- Conclusions:
- (from analogue) The auto-ignition temperature of the target substance is expected to be ca 256°C.
This parameter/method is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard. No particular hazard is anticipated in normal conditions of storage. - Executive summary:
The auto-ignition temperature of the analogue test substance was measured under GLP according to BS 4056 standard (listed in EU A15 guideline).
The test material was injected into a heated flask, until the lowest temperature at which ignition occurs was determined. The relevant parameters (volume, time lag, atmospheric pressure) were recorded for the final result.
The test material has been determined to have an auto-ignition temperature of 256 °C.
Read-across is justified as the target substance is structurally similar (two carbon more in the branched chain length), and has similar boiling and flash points.

Description of key information
(from analogue) AIT expected ca 256°C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 256 °C
Additional information
No data is available for the substance itself. However, a fully reliable experimental study, conducted according to a recognised EU/BS method, and under GLP, is available on an analogue. Therefore the result was extrapolated to the parent target substance.
This parameter is not relevant for classification, however the information is useful for Risk Management Measures regarding storage and process safety, or in case of a fire. No particular hazard is anticipated in normal conditions of storage.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
