- Atm. press.:
- 1 013.25 hPa
- Interpretation of results:
- GHS criteria not met
- Conclusions:
- The flash point was determined to be 136.0 °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 DIN EN ISO 2719 to determine flash point of the test item using a closed cup method. The start temperature for the main test (134 °C) was chosen based on preliminary test. Therefore 56 g of the test item are filled in the cup and heated to the estimated temperature. The measured flash point at atmospheric pressure was corrected to a standard pressure of 1013 hPa. The flash point of the test item was determined to be 136 °C (corrected and rounded down to the nearest multiple of 0.5 °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 (141 °C) was chosen based on available information. Therefore 4 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 138.49 °C (corrected to the ambient pressure). Thus, the flash point of the test item was determined to be 138 °C (corrected and rounded down to the nearest multiple of 0.5 °C) at 1013.25 hPa.

Additional information
Isomeric composition A
A study was conducted according to Regulation (EC) No 440/2008 method A.9 to determine flash point of the test item using a closed cup method. The flash point of the test item was determined to be 136 °C (corrected and rounded down to the nearest multiple of 0.5 °C) at 1013.25 hPa. No observations were made which cause doubt on the validity of the outcome of the study.
Isomeric composition B
