Results and discussion

Auto-ignition temperature (liquids / gases)
Key result
Auto-ignition temperature:
ca. 321 °C
Atm. press.:
> 98.8 - < 100.2 kPa

Any other information on results incl. tables

The auto-ignition temperature ofthe test substance was 321 ± 6°C with an injection volume of 1000 µL. The testing was carried out over a period of two days, the measured atmospheric pressure on the first day was 100.2 kPa and on the second day it was 98.8 kPa, the definitive results were obtained from the second day of testing. The full results are shown in Table 3 (attached).

Applicant's summary and conclusion

The auto-ignition temperature of the test substance was found to be 321 °C at 98.8 to 100.2 kPa, under the conditions of the test.
Executive summary:

In this guideline (EU A.15) study, [conducted with GLP certification], The auto-ignition temperature of the test substance was found to be 321 °C at 98.8 to 100.2 hPa.
