- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 27 APR 2021
- 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)
- Deviations:
- no
- GLP compliance:
- no
- Relative self-ignition temperature:
- 395.2 °C
- Remarks on result:
- other: maybe a false positive result, but indicated for safety reasons
- Conclusions:
- An increase in the temperature of the test substance in comparison to that of the oven was detected; also slightly signs of ignition were observed. As these signs were only slightly and the increase was not very sharp a false positive result cannot be excluded. But for safety reasons the test item is considered as auto-flammable with a Relative Self Ignition Temperature of 395.2 °C under the test conditions.
- Executive summary:
The self-ignition temperature of the test item was assessed in a non-GLP study according to EU Method A.16. An increase in the temperature of the test substance in comparison to that of the oven was detected; also slightly signs of ignition were observed. As these signs were only slightly and the increase was not very sharp a false positive result cannot be excluded. But for safety reasons the test item is considered as auto-flammable with a Relative Self Ignition Temperature of 395.2 °C under the test conditions.

Temperature Data
The temperatures which were measured in the experiment are presented in the following table. As many values were recorded, only the values every 60 minutes are presented.
Time [min.] | Temperature of test item [°C] | Temperature of oven [°C] |
5 (Start) | 22.8 | 21.4 |
60 | 36.4 | 48.5 |
120 | 64.5 | 83.7 |
180 | 96.9 | 119.5 |
240 | 134.3 | 155.8 |
300 | 170.6 | 190.7 |
360 | 210.6 | 222.9 |
420 | 268.2 | 257.8 |
480 | 285.3 | 289.5 |
540 | 311.1 | 321.1 |
600 | 346.2 | 356.8 |
660 | 392.5 | 392.3 |
663 (End) | 400.0 | 395.2 |
After the test, the test item was nearly visually unchanged, just some parts were a bit darker.
An increase in the temperature of the test substance in comparison to that of the oven was detected; also slightly signs of ignition were observed. As these signs were only slightly and the increase was not very sharp a false positive result cannot be excluded. But for safety reasons the test item is considered as auto-flammable with a relative self-ignition Temperature of 395.2 °C under the test conditions.
Description of key information
The self-ignition temperature of the test item was assessed in a non-GLP study according to EU Method A.16. An increase in the temperature of the test substance in comparison to that of the oven was detected; also slightly signs of ignition were observed. As these signs were only slightly and the increase was not very sharp a false positive result cannot be excluded. But for safety reasons the test item is considered as auto-flammable with a Relative Self Ignition Temperature of 395.2 °C under the test conditions.
Key value for chemical safety assessment
- Autoflammability / Self-ignition temperature at 101 325 Pa:
- 395.2 °C
Additional information
No pressure indicated in the study, but room conditions were available. A slight difference from the standard pressure (1013.25 hPa) does not affect the result of the study.
