Description of key information

Flash point: -27.3°C (ASTM D 3828-87), -25°C (closed-cup method)

Key value for chemical safety assessment

Flash point at 101 325 Pa:
-27.3 °C

Additional information

Flash point values of -27.3°C and -25°C were obtained for the submission substance using appropriate closed-cup test methods. The results are considered to be reliable and are used as weight of evidence. In an open-cup test method (ASTM D-92), a flash point value of <-20°C was obtained for the submission substance. The open-cup result is used as supporting data to the two values used as weight of evidence. In a secondary source to which reliability could not be assigned, a flash point value of approximately -26°C was reported for the substance.

Flash point values of -27.3°C and -25°C and a boiling point of 70.3°C indicate that the substance should be classified as a highly flammable (Category 2) liquid according to the criteria of Regulation (EC) No. 1272/2008.
