Description of key information

No flash point up to 200 °C, EU Method A. 9, Sárvári 2012e.

Key value for chemical safety assessment

Additional information

In the key study (Sárvári, 2012e) the flash point of the test material was determined in a GLP study performed according to EU Method A. 9 using the closed cup method.

Approximately 1 mL of the test material was filled into a 4 mL sample cup, a stirring magnet was inserted and it was placed in the tester. The sample was brought up to a starting temperature of 30 °C and the automatic flash point determination was initiated. The oven temperature was raised at a rate of 5 °C/min until it reached a maximum temperature of 200 °C. Oxygen was supplied by an air pulse at a rate of 0.6 sec. The pressure increase was continuously monitored and arcs were initiated at every preset step. The measuring procedure was continued until the pressure increase after an arc exceeded the programmed threshold.

Under the conditions of the test, no flash point was observed up to 200 °C in three tests run in parallel.
