In the preliminary test (heating ramp of 5 K/min, ignition flame was dipped into the test item every 1 K) ignitions were observed at 191 °C and 200 °C. In the main test (constant oven temperature, for each temperature step a fresh sample is used) no ignition was observed within an equilibration time of 120 seconds up to 211.0 °C.

Subsequently the equilibration time was varied and the ignition flame was dipped into the test item approximately every 10 seconds, Table 4.11/3. Each single test was limited to a maximum duration of 300 seconds or until ignition occurred.

The lowest flash point corrected to 1013 hPa was rounded down with an accuracy of 0.5 °C giving a value of 190.0 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item is therefore 190 °C at 1013 hPa
Executive summary:

The flash point of the test substance was determined under GLP according to EU Method A.9 (Flash-Point), using a Rapid equilibrium closed cup method (ISO3679, 2015).

Description of key information

The substance is NOT classified as a Flammable Liquid according to Regulation (EC) N°1272/2008 (CLP criteria)

and UN Globally Harmonized System (GHS criteria).

Key value for chemical safety assessment

Flash point at 101 325 Pa:
190 °C

Additional information

The flash point of the test substance was determined under GLP according to EU Method A.9 (Flash-Point), using a Rapid-equilibrium closed cup method (ISO3679). It is considered as a key study. The result is retained as key data for purpose of CSA.
