Results

 

Preliminary test

 

Atmospheric pressure	97.3 kPa
Relative humidity	About 37%

 

Temperature (°C)			Flash observation
Observed temperature (OT)	Corrected temperature with the calibration curve (CT)	Corrected to Patm (C)
81.5	79.5	80.5	No
91.6	89.5	90.5	No
101.8	99.5	100.5	No
112.0	109.5	110.5	No
122.1	119.5	120.5	No
132.3	129.5	130.5	No
142.5	139.5	140.5	Yes
137.6	134.7	135.7	Yes

 

The flash point was observed between 130.5°C and 135.7°C (corrected values).

 

Main test

 

Atmospheric pressure	97.3 kPa
Relative humidity	About 33%

 

Temperature (°C)			Flash observation
Observed temperature (OT)	Corrected temperature with the calibration curve (CT)	Corrected to Patm (C)
131.8	129.0	130.0	No
132.8	130.0	131.0	No
133.8	131.0	132.0	No
134.8	132.0	133.0	Yes

 

Conclusion

The flash point of the test item was 133.0°C ± 1.0°C (corrected value).

Interpretation of results:

GHS criteria not met

Conclusions:

A flash point of 133.0°C ± 1.0°C (corrected value) at 101.3 kPa was determined for the substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.

Description of key information

Flash point: 133.0 ± 1.0°C at 1013 hPa (ISO 3679)

Key value for chemical safety assessment

Flash point at 101 325 Pa:

133 °C

Additional information

A measured flash point of 133.0 ± 1.0°C at 1013 hPa was determined for the registered substance using a rapid equilibrium closed-cup method in accordance with ISO 3679 Test Method and in compliance with GLP. The result is considered to be reliable and is selected as key study.

In available secondary sources to which reliability could not be assigned, flash points in the range 65-115°C were reported for the substance.

A measured flash point of 133°C at 1013 hPa and predicted boiling point of 280°C at 1013 hPa indicate that the substance should not be classified for flammability in accordance with Regulation (EC) No. 1272/2008.
