Reference
Endpoint:
flash point of flammable liquids
Type of information:
experimental study
Adequacy of study:
key study
Study period:
From 29 June 2012 to 19 November 2012
Reliability:
1 (reliable without restriction)
Rationale for reliability incl. deficiencies:
guideline study
Qualifier:
according to
Guideline:
EPA OPPTS 830.6315 (Flammability)
Deviations:
no
Qualifier:
according to
Guideline:
EU Method A.9 (Flash-Point)
Deviations:
no
GLP compliance:
yes (incl. certificate)
Remarks:
11-04-11
Type of method:
non-equilibrium method
Remarks:
Pensky-Martens
Remarks on result:
other: No flash point below 166.7°C. At this temperature, the test item boiled

In the pre-test, no flash point was detected. Heating was performed up to166.7 °C. At this temperature, boiling was observed with strong smoke emission and the experiment was stopped.

No flash point can be stated for Trifluoromethanesulfonic acid because of boiling of the test item at166.7 °C. Vapours of the test item could not be ignited, neither during the security pre-test (heating in an open test tube) nor in the pre-test in the flash point tester.

Conclusions:
No flash point below 166.7°C. At this temperature, the test item boiled
Executive summary:

The determination of the Flash point was carried out using a procedure designed to be compatible with Method A9 Flash Point of Commission Regulation (EC) No 400/2008 of May 30 2008, EPA OPPTS 830.6315 and GLP. No deviation form the guidelines was observed.

The substance was placed in a test vessel and heated to the test temperature in a Pensky-Martens apparatus (based on non-equilibrium method). Ignition trials were carried out in order to as certain whether or not the sample flashed at the test temperature.

No flash point can be stated for Trifluoromethanesulfonic acid because of boiling of the test item at166.7 °C. Vapours of the test item could not be ignited, neither during the security pre-test (heating in an open test tube) nor in the pre-test in the flash point tester.

Description of key information
