Conclusions:

The flash point of the test item could not be determined according to EU test method A.9 [Council
Regulation (EC) No 440/2008, Official Journal L 142/1 2008] with the Pensky-Martens method
(closed cup) and ace. to the principles given in the standard method DIN EN ISO 2719 (2003).
Therefore only an approximate range can be given.
Flash point (1013 hPa): > 200 °C.

Description of key information

The flash point of the test item could not be determined according to EU test method A.9 [Council

Regulation (EC) No 440/2008, Official Journal L 142/1 2008] with the Pensky-Martens method

(closed cup) and ace. to the principles given in the standard method DIN EN ISO 2719 (2003).

Therefore only an approximate range can be given.

Flash point (1013 hPa): > 200 °C.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
