Reference
Endpoint:
auto-ignition temperature (liquids)
Type of information:
experimental study
Adequacy of study:
key study
Study period:
13 October 2017 to 20 July 2018
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EU Method A.15 (Auto-Ignition Temperature (Liquids and Gases))
Deviations:
no
GLP compliance:
yes (incl. certificate)
Specific details on test material used for the study:
- Purity: > 90%
- Description: Brown liquid
Key result
Auto-ignition temperature:
> 314 - < 320 °C
Atm. press.:
100 kPa

The auto-ignition temperature of the test substance was 317 ± 3°C, with an injection volume of 200 µL. No ignition was observed at 314°C; the margin was therefore set at ± 3°C.

Conclusions:
The auto-ignition temperature of the test substance was 317 ± 3°C.
Executive summary:

The auto-ignition temperature of the test material was conducted in a study performed to the standardized guideline EU Test Method A.15., under GLP conditions. The test substance was injected as droplets with a syringe into the centre of the flask, the time when any flash or flame was observed was read from the chart trace, or the test was run for at least five minutes. The procedure was repeated at different temperatures and with different sample volumes until the minimum value of the ignition temperature was obtained. The auto-ignition temperature of the test substance was 317 ± 3°C, with an injection volume of 200 µL.
