Key result
Flash point:
158 °C
Atm. press.:
96.8 kPa

Preliminary test:

Atmospheric pressure = 97.0 kPa

Relative humidity: about 45%

The flash point was observed between 155.0°c and 160.0°C (corrected values).

Main test:

Atmospheric pressure = 96.8 kPa

Relative humidity: about 47%

       Temperature (°C)  Flash observation
 Observed temperature (OT)  Corrected temperature with the calibration curve (CT)  Corrected to Patm (C)
 156.1 154.0  155.0 No
157.1 155.0  156.0   No
 158.1  156.0  157.0  No
 159.0  157.0  158.0  Yes

The flash point of the test item was 158.0°C +/- 1°C (corrected value).

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item was 158.0°C +/- 1.0°C (corrected value).

Description of key information
