Link to relevant study record(s)
- Endpoint:
- auto-flammability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- other: Followed guideline and GLP requirements.
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
- GLP compliance:
- yes (incl. QA statement)
- Auto-ignition temperature:
- > 243 - < 253 °C
- Atm. press.:
- > 101.93 - < 103.88 kPa
- Remarks on result:
- other:
- Conclusions:
- The test item was determined to have an auto-ignition temperature of 248 +/- 5 degrees C.
- Executive summary:
The auto-ignition temperature was determined by heating aliquots of the test item in a flask, and observing for any ignition. Testing was conducted by a method designed to be compatible with Method A15 “Auto-ignition Temperature Liquids and Gases) of Commission Regulation (EC) No. 440/2008 of 30 May, 2008. The test item was determined to have an auto-ignition temperature of 248 +/- 5 degrees C.

Description of key information
The auto-ignition temperature was determined by heating aliquots of the test item in a flask, and observing for any ignition. Testing was conducted by a method designed to be compatible with Method A15 “Auto-ignition Temperature Liquids and Gases) of Commission Regulation (EC) No. 440/2008 of 30 May, 2008. The test item was determined to have an auto-ignition temperature of 248 +/- 5 degrees C.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 248 °C
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.
