Remark: correction of the observed flash point to a pressure of 760 mmHg. The mean of the three corrected flash point was then rounded to the nearest 0.5°C.
Description of key information
Flash point: 95 - 117°C at 1013 hPa (DIN 51758, ISO 3679:2004, ISO 2719:2002)
Key value for chemical safety assessment
- Flash point at 101 325 Pa:
- 95 °C
Additional information
Four reliable measured flash point results are available for the submission substance. In Greinert 1995, a flash point of 95°C at 1013 hPa was determined for the substance using a Pensky-Martens apparatus in accordance with DIN 51758 Test Method and in compliance with GLP. Also, in Tremain 1995, flash point value of 114°C at 1013 hPa was determined for the substance using a rapid equilibrium method in accordance with ISO 3679 Test Method and in compliance with GLP. Similarly, in Greinert 1995, a flash point value of 117°C at 1013 hPa was determined for the substance using a Pensky-Martens closed cup method in accordance with ISO 2719 Test Method and in compliance with GLP. In Dow Corning Corporation 1991, a flash point value of 99.5°C at 1013 hPa was determined for the substance using a rapid equilibrium method in accordance with ISO 3679 Test Method and in compliance with GLP. The results are considered to be reliable and are used as weight of evidence. Variations in flash point data might result due to differences in purity of each commercial sample tested and the method used.
Flash point values of 95°C to 117°C at 1013 hPa and a measured boiling point of 260°C at 1013 hPa, indicate that the substance should not be classified for flammability according to the criteria of Regulation (EC) No. 1272/2008.
