- Guideline:
- IEC 60079-4 (Electrical apparatus for explosive gas atmospheres. Part 4: Method of test for ignition temperature)
- Version / remarks:
- 1975
- Deviations:
- no
- GLP compliance:
- yes
- Key result
- Auto-ignition temperature:
- 380 °C
- Atm. press.:
- 1 024.1 - 1 030.7 hPa
- Conclusions:
- A minimum auto-ignition temperature of 380°C at 1024.1 – 1030.7 hPa was determined for the substance in accordance with an appropriate test method and in compliance with GLP. The result is considered to be reliable.
Reference
Preliminary study result:
Estimated auto ignition temperature was 410°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.

Conclusion
Commercially available auto-ignition temperature apparatus was used for the determination of the degree of auto-ignitability of 3-(trimethoxysilyl)propiononitrile.
The test substance is auto-ignitable with an auto-ignition temperature at 1024.1 – 1030.7 hPa of 380°C
Description of key information
Auto-ignition temperature: 380°C at 1024.1 to 1030.7hPa (DIN 51794)
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 380 °C
Additional information
An auto-ignition temperature value of 380°C at 1024.1 to 1030.7 hPa was determined for the substance using a relevant test method and in compliance with GLP. The result is considered to be reliable.
