Executive summary:

A study was conducted to determine the flash point of the test substance according to EU Method A.9 (Pensky-Martens, closed cup) with a Pensky-Martens Semi-automatic apparatus PM4 (Petrotest / Anton Paar). The test substance was placed in the test vessel. After closure of the vessel and starting the stirrer, the apparatus was heated. Ignition trials were carried out regularly in order to ascertain whether the sample flashed at the current temperature. Three runs were done. Under the study conditions, the flash point is established at 166°C ± 3°C (Mund, 2017).

Description of key information

The flash point was determined according to EU Method A.9 (Pensky-Martens, closed cup) (Mund, 2017).

Key value for chemical safety assessment

Flash point at 101 325 Pa:
166 °C
