- Conclusions:
- The test item has a flash point of 104.5 °C (average corrected and rounded down to the nearest multiple of 0.5 °C) according to Regulation EC No. 440/2008 Method A.9. Flash Point, DIN EN ISO 2719 (2003).
- Executive summary:
A study was conducted according to Regulation (EC) No 440/2008 method A.9 and ISO 2719 to determine the flash point of the test item using a closed cup method withPensky-Martens apparatus. A preliminary test was performed with a search program to determine the rough flash point.For the main test about 70 g of the test item were filled in the cup. The estimated flash point from the preliminary test was used as target temperature for the main test - 104 °C. The first ignition trial of the main test was performed at a test item temperature 23±5 °C below the approximate flash point determined in the preliminary test, with a stirrer speed of 90 - 120 rpm and a heating rate of 5 – 6 K/min. The test was performed twice.The measured flash point at atmospheric pressure was corrected to a standard pressure of 1013 hPa. The flash point was determined to be at 104.82 °C (corrected to the ambient pressure). Thus, the flash point of the test item was determined to be 104.5 °C (corrected and rounded down to the nearest multiple of 0.5 °C) at 1013.25 hPa.

In the main test the lowest temperature where an ignition was observed was 104.0 °C.
The mean measured flash point is corrected to the ambient pressure to be 104.82 °C.
The resulting average corrected flash point rounded down to the nearest multiple of 0.5 °C is 104.5 °C.
Description of key information
The test item has a flash point of 104.5 °C (average corrected and rounded down to the nearest multiple of 0.5 °C) according to Regulation EC No. 440/2008 Method A.9. Flash Point, DIN EN ISO 2719 (2003).
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 104.5 °C

Classification, Labelling, and Packaging Regulation (EC) No 1272/2008
With a measured flash point > 60 °C, the test item does not have to be classified as flammable liquid according to GHS or CLP Regulation EC 1272/2008 Annex 1.
