Results and discussion
Auto-ignition temperature (liquids / gases)
- Key result
- Auto-ignition temperature:
- 410 °C
- Atm. press.:
- >= 1 016.5 - <= 1 021 hPa
Any other information on results incl. tables
Preliminary test
The estimated auto-ignition temperature was 420°C.
Main study
Ignition of the test item 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. According to the guidelines, no further testing was required.
The lowest temperature at which ignition of the test item occurred was 411°C. This temperature was rounded down to the nearest multiple of 5°C giving an auto-ignition temperature of the test item of 410°C.
Applicant's summary and conclusion
- Conclusions:
- A commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of T001590.
The test item is auto-ignitable with an auto-ignition temperature of 410°C at 1016.5 - 1021.0 hPa.
