- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: IEC standard 79-4
- Deviations:
- no
- GLP compliance:
- yes
- Auto-ignition temperature:
- 230 °C
- Atm. press.:
- ca. 1 002.1 - ca. 1 019.8 hPa
- Remarks on result:
- other: The lowest temperature at which ignition of the test substance occurred was 234°C
- Conclusions:
- An auto ignition temperature of 230°C at 1002.1 – 1019.8 hPa was determined for the substance in accordance with an appropriate test method and in compliance with GLP. The result is considered reliable.
Reference
Preliminary study result:
Estimated auto ignition temperature was 250°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 <10°C.
The lowest temperature at which ignition of the test substance occurred was 234°C. This temperature was a multiple of 5°C and therefore given as the auto-ignition temperature of the test substance.
