- Key result
- Flash point:
- 151.5 °C
- Atm. press.:
- 1 013.25 hPa
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The resulting corrected flash point rounded down to the nearest multiple of 0.5 °C was determined to be 151.5 °C.
- 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 (170 °C) was chosen based on he preliminary test. Therefore 2 mL 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 151.9 °C (corrected to the ambient pressure). Thus, the flash point of the test item was determined to be 151.5 °C (corrected and rounded down to the nearest multiple of 0.5 °C) at 1013.25 hPa.

In the preliminary test the ignition flame was enlarged at a temperature of approx. 150 °C. At 180 °C the whole sample burned in the apparatus, which could be observed visually. The apparatus detected no ignition. Thus the main test was performed, starting at 170 °C.

In the main test the lowest temperature where an ignition was observed was 152.0 °C.
The measured flash point is corrected to the ambient pressure to be 151.9 °C.
The resulting corrected flash point rounded down to the nearest multiple of 0.5 °C is 151.5 °C.
Description of key information
The resulting corrected flash point rounded down to the nearest multiple of 0.5 °C was determined to be 151.5 °C.
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 151.5 °C
