Interpretation of results:
Category 3 (flammable liquids) based on GHS criteria
Conclusions:
A flash point value of 54°C at 1013 hPa was determined for the substance in accordance with a relevant test method and in compliance with a known quality system (ISO 9001:2008). The result is considered to be reliable.

Description of key information

Flash point: 54°C at 1013 hPa (ISO 3679)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
54 °C

Additional information

A measured flash point value of 54°C at 1013 hPa was determined for the substance using a rapid equilibrium closed-cup method in accordance with ISO 3679 and in compliance with a known quality system (ISO 9001:2008). 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 point values of 37.2 - 54°C at 1013 hPa were reported for the substance.

 

A flash point of 54°C at 1013 hPa and a measured boiling point of 167.3°C at 1013 hPa, indicate that the substance should be classified as a flammable liquid according to the criteria of Regulation (EC) No 1272/2008.
