The flash point of the substance was determined to be 165 °C at 101.325 kPa.
Executive summary:

The flash point was determined according to EU Method A.9 using an Eraflash flash-point tester in the closed cup method consistent with ISO 2719, ASTM D93 and ASTM D7094: Modified Continuously Closed Cup Flash Point (MCCCFP) test under GLP. The Eraflash tester employs a small volume of test item which reduces the risk of fires or other uncontrolled reactions of substances with an unknown flash point. The test cup was filled with approximately 2 ml test item and placed in the holder of the flash-point tester. The sample was stirred during heating. The ignition of the sample vapour was performed by an electric arc and ignition was automatically detected by the flash point tester. The flash-point is automatically corrected for atmospheric pressure by the flash point tester. Following a preliminary test starting at 25°C, an attempt was made to ignite the vapour of the test item for every 2°C temperature rise. The test cup was heated at a rate of 5 ± 0.5°C/minute. The estimated flash point was 155°C. The definitive test was conducted in triplicate. Starting at 132 and 139°C, respectively. Ignition was tested for every 2°C temperature rise. Test 1 indicated a flash point of 162°C. Test 2 and 3 indicated a flash point of 165°C, in duplicate. Under the conditions of the study, the flash-point of the test substance is 165 °C at 101.325 kPa.
