- reference to same study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.9 (Flash-Point)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- non-equilibrium method closed cup
- Key result
- Remarks on result:
- no flash point - measurement carried out until boiling temperature
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- No flash point was observed up to 110.0 °C (corrected value).
- Executive summary:
In this study (2012), the determination of the flash point of the reaction mass potassium trifluoromethanesulfinate and potassium trifluoroacetate was performed according to the guideline EU A9.
No flash point was observed up to 110.0 °C (corrected value).
Based on this result, the reaction mass of TFSK/TFAK is not classified for flammability.
Reference
Preliminary test
The test conditions were:
Atmospheric pressure of about 98.4 kPa
Relative humidity of about 58%
The preliminary test results are given inthe following table. At 110.0 °C, the test item boiled and overflowed out of the cup just before the introduction of the flame. The test was therefore terminated.

Main test
Considering the observations of the preliminary test at 110.0 °C, no main tests were performed.
Description of key information
The flash point of the reaction mass in aqueous solution is higher than 110°C.
Key value for chemical safety assessment
Additional information
One experimental study performed according to the EC A9 method is available on the reaction mass of potassium trifluoromethanesulphinate and potassium trifluoroacetate in aqueous solution.
At 110 °C, the test item boiled and overflowed out of the cup just before the introduction of the flame. The test was therefore terminated and the flash point is considered to be higher than 110°C. Therefore, the aqueous solution of the reaction mass is non-flammable.
