The flash point is defined as the lowest measured value out of all performed tests.

There was no flash point up to 110 °C (760 Torr) = 383.2 K (1.013 bar)

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item is >110 °C.
Executive summary:

The flash point of the test item was determined in a GLP study according to EU test method A.9. The flash point of the test item

is >110 °C. The test item does not have to be classified as a flammable liquid according to Regulation (EC) 1272/2008.

Description of key information

The flash point of the test item is >110 °C, since no flash point could be observed up to 110 °C. A value of 110 °C was entered as the key value.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
110 °C

Additional information

Based on the classification criteria of Regulation (EC) 1272/2008, the test item does not have to be classified as a flammable liquid.
