The flash point corrected to 1013 hPa is rounded down with an accuracy of 0.5°C to 106.5°C
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.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
