Auto flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- auto-flammability
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- June 1996
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- test procedure in accordance with national standard methods with acceptable restrictions
- Remarks:
- Test methods are described in a separate document.
- Qualifier:
- according to guideline
- Guideline:
- other: DIN 51794
- Principles of method if other than guideline:
- The test for the determination of the auto flammability was preformed according to DIN 51794.
1) Apparatus:
Heating oven with erlmeyer flask according to DIN 51794
2) Input:
1-6 drops of the testing substance (Eppendorf 100 µL with glas top)
3) Performance:
According to DIN 51794, but with several deviations:
- the tests were preformed by increasing temprature starting with 50°C up to 600 °C
- installation of a second temperature sensore, which improves the temperature determination
- in the range of the lowest ignition temperature several ignition test are preformed until the lowest ignition temperature is determined to accurate
5°C and under which value at least 3 ignition tests in 5°C-steps do not lead to ignition. - GLP compliance:
- not specified
- Key result
- Auto-ignition temperature:
- 500 °C
- Remarks on result:
- other: No information on pressure reported
- Conclusions:
- Auto flammability of 4-tert-Butylbenzonitril: 500 °C
- Executive summary:
A test for the determination of the auto flammability of 4 -tert-Butylbenzonitrile was performed according to DIN 51794. The result was that the auto flammability of 4-tert-Butylbenzonitril occurs at 500 °C.
