Description of key information
Flash point: 70.5 ± 0.5°C at 1013 hPa (ISO 3679)
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 70.5 °C
Additional information
A measured flash point value of 70.5 ± 0.5°C at 1013 hPa was determined for the 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.
In available secondary sources to which reliability could not be assigned, flash point values of 69°C and 74°C were reported for the substance.
A measured flash point value of 70.5 ± 0.5°C at 1013 hPa and a boiling point of 224°C at 1013 hPa indicate that the substance should not be classified for flammability in accordance with Regulation (EC) No. 1272/2008.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
