Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- weight of evidence
- Study period:
- 20/02/2007
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Remarks:
- No information is provided on the method used. The substance identification is not complete (purity/composition missing). Therefore validation cannot be granted.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- No information is provided on the method used, however, an automated AIT apparatus was used, and description of results is given as for EU A15 (temperature, atmospheric pressure, volume injected, time lag before ignition)
- GLP compliance:
- no
- Key result
- Auto-ignition temperature:
- 240 °C
- Atm. press.:
- ca. 977 mBar
- Executive summary:
The Auto-Iginition Temperature of the test substance was determined with an automated apparatus. No guideline is specified, but the method is supposed similar to EU A.15.
The AIT has been determined to be 240°C, at 977 mbar.

- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- documentation insufficient for assessment
- Remarks:
- No information is provided on the method used. The substance identification is not complete (batch N° and purity/composition missing). Therefore validation cannot be granted.
- Qualifier:
- no guideline followed
- Principles of method if other than guideline:
- No information is provided on the method used, however, an automated AIT apparatus was used, and description of results is given as for EU A15 (temperature, atmospheric pressure, volume injected, time lag before ignition)

- Key result
- Auto-ignition temperature:
- 290 °C
- Atm. press.:
- 985 mBar
- Executive summary:
The Auto-Iginition Temperature of the test substance was determined with an automated apparatus. No guideline is specified, but the method is supposed similar to EU A.15.
The AIT has been determined to be 290°C, at 985 mbar.

Description of key information
AIT between 240 and 290°C, depending on purity.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 240 °C
Additional information
Two experimental studies are available. Documentation on test method and sample composition is not sufficient to assess reliability, however the method is supposed to be similar to EU A15, and test substances supposed to be of different purity. The result for the raw grade is 240°C, and the result for the refined grade is 290°C, which is quite consistent. For safety purpose, the lower result is retained as key value.
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).
