Conclusions:

The auto-ignition temperature at 1015-1019 hPa of the substance was determined to be ≤ 210°C.

Executive summary:

The auto-ignition temperature of the substance was determined in a GLP study according to EC A.15, DIN 51794 and IEC 60079-4 to be ≤ 210°C. Three tests were performed, at 1015 -1019 hPa. No minimum auto-ignition temperature as a function of injection volume was observed up to the maximum injection volume of 1000 μL. The lowest temperature at which ignition of the test item occurred was 211°C (at an injection volume of 1000 µL). This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of 210°C. Due to practical reasons, the experiment cannot be performed at larger volumes than tested. The final result can just be determined as maximum auto-ignition temperature with the real value ≤ 210°C.

Description of key information

 The auto-ignition temperature of the substance at 1015 - 1019 hPa was determined in a GLP study according to EC A.15, DIN 51794 and IEC 60079-4 to be ≤ 210°C. 

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:

210 °C

Additional information

Key value: ≤ 210°C at 1015 -1019 hPa.

Three tests were performed. No minimum auto-ignition temperature as a function of injection volume was observed up to the maximum injection volume of 1000 μL. The lowest temperature at which ignition of the test item occurred was 211°C (at an injection volume of 1000 µL). This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of 210°C. Due to practical reasons, the experiment cannot be performed at larger volumes than tested. The final result can just be determined as maximum auto-ignition temperature with the real value ≤ 210°C. Though the exact auto-ignition could not be determined, it is expected to be higher than the flash point, which is 95°C.
