Atm. press.:
103 kPa

Results of the flash point determination are shown in the following table:

Temperature (°C) Observations
21 (fresh sample) to 71* No flash for each temperature assessed
21 (fresh sample) to 71* No flash for each temperature assessed
101 (fresh sample) No flash
106 Blue flash spread across the sample cup
106 (fresh sample) No flash
111 Blue flash spread across the sample cup
111 (fresh sample) Blue flash spread across the sample cup
106 (fresh sample) No flash
107 (fresh sample) Blue flash spread across the sample cup
107 (fresh sample) Blue flash spread across the sample cup
105 (fresh sample) No flash
105 (fresh sample) No flash

Atmospheric pressure = 103 kPa

Observed flash point = 107°C

Corrected flash point = 106.7°C

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item has been determined to be 107 ± 2 °C.
Executive summary:

Flash Point. 107 ± 2°C, using a closed cup equilibrium method designed to be compatible with Method A.9 Flash Point of Commission Regulation (EC) No 440/2008 of 30 May 2008.
