The lowest flash point corrected to 1013 hPa was rounded down with an accuracy of 0.5 °C giving a value of 36.0 °C.

Interpretation of results:

Category 3 (flammable liquids) based on GHS criteria

Conclusions:

The flashpoint of the test item was determined to be 36.0 °C under atmospheric conditions (1013 hPa).

Executive summary:

The flash point was determined according to EU method A.9 in a closed cup experiment according to rapid equilibrium method. The test item was filled into the test vessel and the flash point was determined with temperature steps of 0.5 K. For each temperature step a fresh sample was used. The main test was performed at constant temperature and equilibrium conditions. The final flash point rounded down with an accuracy of 0.5 K was determined to be 36.0 °C.

Description of key information

The flashpoint of the test item was determined to be 36.0 °C under atmospheric conditions (1013 hPa) (reference 4.11-1).

Key value for chemical safety assessment

Flash point at 101 325 Pa:
