Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- 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))
- GLP compliance:
- yes (incl. QA statement)
- Auto-ignition temperature:
- 585 °C
- Atm. press.:
- 997.8 hPa
- Conclusions:
- The auto-ignition temperature of the test item according to the auto-ignition test conditions in the
sense of the European Commission Regulation (EC) No. 440/2008, Method A.15. was 585 °C. - Executive summary:
The auto-ignition temperature of the test item of the test item was determined according to European Commission Regulation (EC) No. 440/2008, A.15. Auto-ignition temperature (liquids and gases).
Approximately the lowest temperature at which an ignition in the test was observed is
used as starting point for the main test.
In the main test, the ignition at this temperature is repeated, the temperature is decreased by 5 K
and the test is repeated. This procedure is repeated until no ignition is observed. Subsequently
the amount of test item added to the apparatus is varied at the same temperature. If an ignition
occurs during the variation of the amount of test item, the temperature is decreased again by 5 K
and the procedure started again. The test is continued by choosing the lowest temperature found
in the previous step where an ignition occurred. The test temperature is lowered in intervals approximately 2 K until ignition occurs within min after introducing sample amount substance as found before. that temperature ignition occurred min the
amount of the test substance is varied stepwise until ignition occurs or the absence of an ignition
was confirmed using different amounts.
The test temperature, atmospheric pressure, of the sample used and the time-lag until
ignition occurs are reported.The main test is repeated at least two times (using 2 K steps) to verify the result of the first main
test. At least three lowest results of the main test series have to be within a range of 1 0 K for autoignition
temperatures below 300 °and within range 20 K auto-ignition-temperatures
above 300 °Due to safety reasons and according to the standard DIN 51794:2003-05 the lowest measured
temperature at which an ignition is observed, is rounded to the next lower number divisible by 5.

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.
