Mean flash point observed at 620 mm Hg = 189 °C

Mean corrected flash point at 760 mm Hg = 194 °C

The flash point was corrected to the normal atmospheric pressure of 760 mm Hg using the following equation:

 

Corrected flash point = T + 0.033 (760 – P)

 

Where

T = observed flash point (°C)

P = atmospheric standard barometric pressure (mm Hg)

Interpretation of results:
GHS criteria not met
Conclusions:
Under the conditions of the study, the flash point of the test material was determined to be 194 °C at atmospheric pressure.
Executive summary:

The flash point of the test material was determined under GLP conditions, in accordance with the standardised guideline EU Method A.9, using the closed cup method. Under the conditions of the study, the flash point of the test material was determined to be 194 °C at atmospheric pressure (760 mm Hg).

Description of key information

Experimental study conducted according to recognised testing guideline with GLP certification.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
194 °C

Additional information

The flash point of the test material was determined under GLP conditions, in accordance with the standardised guideline EU Method A.9, using the closed cup method. Under the conditions of the study, the flash point of the test material was determined to be 194 °C at atmospheric pressure (760 mm Hg).

The study was performed in line with GLP and an accepted standardised guideline with a good level of reporting. The study was therefore assigned a reliability score of 1 and considered suitable for assessment as an accurate reflection of the substance.

The available data are considered to be complete and the result determined, flash point 194 °C at 760 mm Hg, was taken forward for risk assessment.
