Auto flammability
Administrative data
Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- March 26 - 31, 2003
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- ASTM E659 (Standard test method for autoignition temperature of liquid chemicals)
- Deviations:
- no
- GLP compliance:
- yes
- Remarks:
- OECD GLP
- Key result
- Relative self-ignition temperature:
- >= 317 - <= 323 °C
- Conclusions:
- Under the conditions of this study the observed autoignition temperature of the test material was 320 ± 3 °C at 101.8 kPa. The observed ignition delay time of the test material was 14 s.
- Executive summary:
The autoflammability of the test material was investigated in accordance with the standardised guidelines ASTM E659-78, under GLP conditions.
The test material (approx. 250 mg) was placed in a heated 0.5-L flask, and the flask was observed in the dark. This procedure was repeated, varying the temperature, and the lowest temperature that the test material was observed to ignite was the autoignition temperature. The “ignition delay time”, the time between addition of the test material to the flask and ignition, was also recorded.
Under the conditions of this study the observed autoignition temperature of the test material was 320 ± 3 °C at 101.8 kPa. The observed ignition delay time of the test material was 14 s.

Additional information
The autoflammability of the test material was investigated in accordance with the standardised guidelines ASTM E659-78 (2000), under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
The test material (approx. 250 mg) was placed in a heated 0.5-L flask, and the flask was observed in the dark. This procedure was repeated, varying the temperature, and the lowest temperature that the test material was observed to ignite was the autoignition temperature. The “ignition delay time”, the time between addition of the test material to the flask and ignition, was also recorded.
Under the conditions of this study the observed autoignition temperature of the test material was 320 ± 3 °C at 101.8 kPa. The observed ignition delay time of the test material was 14 s.
