Main test:

The results of the main measurements and temperatures where ignition (+) was detected and no ignition (-) detected are reported in the table below.

Test item (mL)	Temperature (°C)	Ignition/no ignition (+/-)	Barometric pressure (hPa)
4	107.0	+	1008.7
4	106.5	-	1008.7
4	107.0	+	1008.7
4	106.5	+	1008.7
4	106.0	-	1008.7
4	106.5	+	1008.7
4	106.0	-	1008.7
4	106.5	+	1008.7

The flash point corrected to 1013 hPa is rounded down with an accuracy of 0.5°C to 106.5°C

Interpretation of results:

GHS criteria not met

Conclusions:

A flash point of 106.5°C at 1013 hPa was determined for the substance using relevant test method. The result is considered to be reliable.

Description of key information

Flash point: 106.5°C at 1013 hPa (ISO 3679)

Key value for chemical safety assessment

Flash point at 101 325 Pa:

106.5 °C

Additional information

A measured flash point value of 106.5°C at 1013 hPa was determined for the substance using a rapid equilibrium closed-cup method in accordance with ISO 3679 Test Method but not in compliance with a known quality system. The result is considered to be reliable and was selected as the key study.

In a secondary source to which reliability could not be assigned, flash point of 77°C at 1013 hPa was reported for the substance.

Differences in flash point measurements may result from differences in purity of the test substance (presence of volatile impurities) and the method used.

A measured flash point of 106.5°C at 1013 hPa and a measured boiling point of 242°C at 1013 hPa, indicate that the substance should not be classified for flammability according to the criteria of Regulation (EC) No. 1272/2008.
