Reference
Preliminary study result:
Estimated auto-ignition temperature was 460°C.
Main study result:
The result of the main study are shown in Table 2. Ignition of the test substance within 5 minutes after introduction was observed with each sample volume and with each test a minimum auto-ignition temperature was obtained. The maximum deviation between the three values was <20°C.
The lowest temperature at which ignition of the test substance occurred was 380°C. This temperature was a multiple of 5°C and therefore given as the auto-ignition temperature of the test substance.

Description of key information
Auto-ignition temperature [2,4,6-trimethyl-2,4,6-tris(3,3,3-trifluoropropyl)cyclotrisiloxane]: 380°C at 1004.1 to 1021.1 hPa (EU Method A.15)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 380 °C
Additional information
A measured auto-ignition temperature of 380°C at 1004.1 to 1021.1 hPa was determined for the substance in accordance with EU Method A.15 and in compliance with GLP. The result is considered to be reliable.
