Applicant's summary and conclusion

Interpretation of results:
Category 2 (highly flammable liquids) based on GHS criteria
Conclusions:
The closed cup method was applied for the determination of the flash-point of 2,2,2-trifluoro-1-(trifluoromethyl)ethyl methacrylate.
The flash-point of the test item was 22°C.
Since the flash-point of the test item was in the range in the range of 23°C  2°C the equilibrium method was applied. The flash-point of the test item obtained with the equilibrium method was 15°C.
