The closed-cup flash point temperature of the test item has been determined to be 146.5°C at 100.4 kPa.

Description of key information

The flash point of the substance was determined in a GLP study according to test method EC A.9 (K1; Younis, 2017). The flash point of the test item has been determined to be 146.5 °C at 100.4 kPa using a closed cup equilibrium method.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
146.5 °C

Additional information

The flash-point is expressed at an atmospheric pressure of 100.4 kPa.
