In the main test the lowest temperature where an ignition was observed was 61.0 °C.

The mean measured flash point is corrected to the ambient pressure to be 61.25 °C.

The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 61.0 °C.

Interpretation of results:
GHS criteria not met
Conclusions:
The test item has a flash point of 61.0 °C at 1013.25 hPa.
Executive summary:

A study was conducted according to Regulation (EC) No 440/2008 method A.9 and DIN EN ISO 2719 to determine flash point of the test item using a closed cup method with Pensky Martens apparatus. 61 g of the test item were filled in the cup and heated to the estimated temperature. The measured flash point was corrected to the ambient pressure of 1013 hPa. The flash point of the test item was determined to be 61.0 °C (corrected and rounded down to the nearest multiple of 0.5 °C) at 1013.25 hPa.

Description of key information

The test item has a flash point of 61.0 °C at 1013.25 hPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:

Additional information

A study was conducted according to Regulation (EC) No 440/2008 method A.9 and DIN EN ISO 2719 to determine the flash point of the test item using a closed cup method with Pensky Martens apparatus (2017). In a preliminary test, a flash point of 61.0 °C was determined. 61 g of the test item were filled in the cup and heated to the estimated temperature. The measured flash point was corrected to the ambient pressure of 1013 hPa. The flash point of the test item was determined to be 61.0 °C (corrected and rounded down to the nearest multiple of 0.5 °C) at 1013.25 hPa.
