Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 14 December 2017 to 31 January 2018
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: UN Manual of Tests and Criteria: Test N.4 (Test method for self-heating substances)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- Under the conditions of the test no self-ignition of the test material was recorded and the temperature of the sample did not exceed the oven temperature by 60 °C. The result is considered negative.
- Executive summary:
The self ignition of the test material was investigated in a study which was conducted in accordance with the standardised guideline UN Method N.4 under GLP conditions.
The edge length of the cubic sample container was 100 mm. The internal temperature in the oven was recorded at 140 °C (corrected value). The temperature of the test material was recorded between 139 and 140 °C (corrected values).
At the start of the test, the test material was a white powder and it remained a white powder after the test.
Under the conditions of the test no self-ignition of the test material was recorded and the temperature of the sample did not exceed the oven temperature by 60 °C. The result is considered negative.

Additional information
The self ignition of the test material was investigated in a study which was conducted in accordance with the standardised guideline UN Method N.4 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 edge length of the cubic sample container was 100 mm. The internal temperature in the oven was recorded at 140 °C (corrected value). The temperature of the test material was recorded between 139 and 140 °C (corrected values).
