auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
Experimental phase: 17 October 2017 to 23 March 2018.
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
GLP compliance:
yes (incl. QA statement)
Key result
Auto-ignition temperature:
338 °C
Atm. press.:
102.2 kPa

No cool flames were observed. Ignition produced an orange flame and an orange/green flame.

The autoignition temperature of the test substance was determined to be 338°C.
Executive summary:


The autoignition temperature of the test substance was assessed using the procedure described in EU Regulation (EC) 440/2008, Annex Part A test A15.


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.

Results and Conclusion

The autoignition temperature of the test substance was determined to be 338°C.

Description of key information

Self-ignition temperature of the test substance.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
