auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
according to guideline
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
according to guideline
DIN 51794 (Testing of mineral oil hydrocarbons - Determination of ignition temperature)
GLP compliance:
Auto-ignition temperature:
370 °C
Atm. press.:
>= 1 021 - <= 1 022 hPa

The estimated auto-ignition temperature from the preliminary test was determined to be ca. 450°C.

In the main study ignition of the test item was observed within 5 minutes of introduction with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was < 10°C. According to the guidelines, no further testing was required. The lowest temperature at which ignition of the test item occurred was 372°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 370°C.

The test substance auto-ignition temperature was determined to be 370°C.

Description of key information

Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of the substance. The test item is auto-ignitable with an auto-ignition temperature of 370°C. The atmospheric pressure was 1022 and 1021 hPa.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
