In the main test the lowest temperature where an ignition was observed was 92.0 °C The measured flash point is corrected to the ambient pressure to be 92.25 °C The resulting corrected flash point rounded down to the nearest multiple of 0.5 °C is 92 0 °C

 

Interpretation of results:
GHS criteria not met
Conclusions:
The flash point of the test item was determined to be 92 °C at 1013.25 hPa.
Executive summary:

A study was conducted according to Regulation (EC) No 440/2008 method A.9, OPPTS 830.6315 and ISO 3679:2004 to determine flash point of the test item using a closed cup method. The start temperature for the main test (98 °C) was chosen based on available information. Therefore 2 g of the test item are filled in the cup and heated to the estimated temperature. Then the substance was maintained for at least 1 minute at this temperature. The flame was dipped in the cup and it was checked if ignition occurred. The measured flash point at atmospheric pressure was corrected to a standard pressure of 1013 hPa. The flash point was determined to be at 92.25 °C (corrected to the ambient pressure). Thus, the flash point of the test item was determined to be 92.0 °C (corrected and rounded down to the nearest multiple of 0.5 °C) at 1013.25 hPa.

Description of key information

The flash point of the test item was determined to be 92 °C at 1013.25 hPa.

Key value for chemical safety assessment

Flash point at 101 325 Pa:
