Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
- Study period:
- 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:

- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- Principles of method if other than guideline:
- The test is conducted in accordance with the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A.15.
The test covers the determination of hot and cool flame autoignition temperatures of a liquid chemical in air at atmospheric pressure in a uniformly heated vessel. A small, metered sample of the product to be tested is inserted into a uniformly heated 500 ml glass flask containing air at a predetermined temperature. The contents of the flask are observed in a dark environment for 10 minutes following insertion of the sample, or until autoignition occurs. Autoignition is identified by the sudden appearance of a flame inside the flask and by a sharp rise in the temperature of the gas mixture. The lowest internal flask temperature at which the hot-flame ignition occurred for a series of prescribed sample volumes is taken to be the hot-flame autoignition (AIT) of the chemical in air at atmospheric pressure. Ignition delay times (ignition time lags) are measured in order to determine the ignition delay / ignition temperature relationship. The lowest temperature at which cool flames (CFT) are observed is also recorded. In all instances the ignition delay times are recorded. - GLP compliance:
- yes (incl. QA statement)
- Key result
- Auto-ignition temperature:
- 257 °C
- Atm. press.:
- 101.9 kPa
- Remarks on result:
- other: No cool flames were observed. Ignition produced an orange / pink flame.

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.
