Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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:
- From 2013-05-02 to 2013-05-03
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Remarks:
- The study was conducted according to an internationally recognised method, and under GLP. No deviation was reported. Substance ID is adequately specified with purity. Therefore full validation applies.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Qualifier:
- according to guideline
- Guideline:
- IEC 60079-4 (Electrical apparatus for explosive gas atmospheres. Part 4: Method of test for ignition temperature)
- Version / remarks:
- Anon (1987), Electrical apparatus for explosive gas atmospheres. Part 4: Method of test for ignition
temperature. IEC Publications 79-4, p1-19. - GLP compliance:
- yes (incl. QA statement)
- Remarks:
- UK GLP Compliance Programme (inspected on 10 July 2012 / signed on 30 Nov. 2012)
- Key result
- Auto-ignition temperature:
- 388 °C
- Atm. press.:
- 101.2 - 102.1 kPa
- 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 IEC 79-4 method (listed in EU A15 guideline).
Different volumes of test substance were injected into a heated flask, until the lowest temperature at which ignition occurs was determined. The relevant parameters were recorded for the final result.
The measured auto-ignition temperature of the test substance is 388°C.

Description of key information
No particular hazard is anticipated in normal conditions of storage.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 388 °C
Additional information
A fully reliable experimental study, conducted according to a recognized IEC/EC method and under GLP, is available. It is therefore considered as a key study. The result is retained as key data for purpose of CSA.
This parameter is not relevant for classification, however the information is useful regarding process safety and potential additional fire hazard.
