Reference
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
Auto-ignition temperature:
465 °C
Remarks on result:
other: atmospheric pressure assumed

The lowest result in the main test run was found to be 465°C. The lowest result in the repeat test was 465°C, too.

Conclusions:
The auto ignition temperature of the test substance is specified as 465°C.
Executive summary:

The test was performed as stipulated in Test Procedure A 15 and DIN 51794.

Narrow-neck Erlenmeyer flasks with a nominal volume of 200 ml were used as ignition vessels. A 'Eurotherm' regulating system was used to control the temperature of the electric furnace. Different sample sizes were added for the individual measurements. Testing commenced with a range-finding determination of the auto ignition temperature. An initial ignition was observed at a temperature of 470°C. Proceeding from this temperature, the lowest result in the main test run was found to be 465°C. The lowest result in the repeat test was 465°C, too.

The auto ignition temperature of the test substance is specified as 465°C.
