Applicant's summary and conclusion
- Conclusions:
- The auto-ignition temperature of the test item was 432 °C ± 3 °C (corrected temperature).
- Executive summary:
The determination of the auto-ignition temperature of Isopropyl trifluoroacetate was performed according to the Commission Regulation (EC) N° 440/2008 A15 method.
The test is repeated at different temperatures (from about 100°C to about 600°C) until the minimum value of the ignition temperature was observed.
The volume of the test item injected in the oven was 70 µL.
For the preliminary test, the auto-ignition temperature was situated between 431°C and 442°C (corrected values).
The auto-ignition temperature of the test item was 432°C +/- 3°C (corrected temperature).
