Key result
Auto-ignition temperature:
265 °C
Atm. press.:
>= 998.3 - < 1 000 hPa

Preliminary test: The lowest self-ignition temperature of the test substance was determined to be 267°C.

Conclusions:
Under the conditions of the study, the self-ignition temperature of the test substance was determined to be 265°C at barometric pressure 998.3-1000.0 hPa.
Executive summary:

A study was conducted to determine the self-ignition temperature of the test substance according to the auto-flammability test conditions as mentioned in the European Commission Regulation (EC) No. 440/2008, Method A.15. and DIN 51794. The apparatus used to determine the auto-flammability was constructed according to IEC 79-4. Under the test conditions, the self-ignition temperature of the test substance was determined to be 265°C at barometric pressure 998.3-1000.0 hPa (Smeykal, 2010a).

Description of key information

A study was conducted to determine the self-ignition temperature of the test substance according to the auto-flammability test conditions as mentioned in the European Commission Regulation (EC) No. 440/2008, Method A.15. and DIN 51794.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
265 °C

Additional information

Considering data from experimental studies with the test substance and other category members, the autoflammability temperature was generally greater than 265°C and it was not considered auto-flammable.
