Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 21 June 2017 to 26 June 2017
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Version / remarks:
- 2008
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Relative self-ignition temperature:
- 222 °C
- Conclusions:
- Under the conditions of this study, the average relative self-ignition temperature of the test material was observed at 222 °C. The minimum value of the replicate tests was 220 °C.
- Executive summary:
The relative self-ignition temperature of the test material was investigated in accordance with the standardised guideline EU Method A.16, under GLP conditions.
Four replicate tests were performed at about 97.3 – 97.7 kPa atmospheric pressure. In all of tests the temperature of oven decreased suddenly, when the test material started to warm up with self-ignition; therefore the oven temperature at which the sample was 400 °C, can not be evaluated. The decreasing of oven temperature seems to an individual character of the test material. Considering that the temperature of oven increased gradually (approximately 0.1 °C per measurement points), the self-ignition temperature of test material can be estimated with a good approximation.
Under the conditions of this study, the average relative self-ignition temperature of the test material was observed at 222 °C. The minimum value of the replicate tests was 220 °C.
Reference
- Four replicate tests were performed. The average of the measured data was reported. In all of tests the temperature of oven decreased suddenly, when the test material started to warm up with self-ignition; therefore the oven temperature at which the sample was 400 °C, can not be evaluated. The decreasing of oven temperature seems to an individual character of the test material. Considering that the temperature of oven increased gradually (approximately 0.1 °C per measurement points), the self-ignition temperature of test material can be estimated with a good approximation.
- The average relative self-ignition temperature of the test material was observed at 222 °C. The minimum value of the replicate tests was 220 °C.

Additional information
The relative self-ignition temperature of the test material was investigated in accordance with the standardised guideline EU Method A.16, under GLP conditions. The study was awarded a reliability score of 1 in accordance with the criteria set forth by Klimisch et al. (1997).
