Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study

- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Version / remarks:
- 2016
- Deviations:
- no
- GLP compliance:
- yes
- Specific details on test material used for the study:
- Batch No.: 190722
Purity: > 99 wt% - Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- The test item is considered ‘not self-ignitable’.
- Executive summary:
The self-ignition temperature of test item was determined using a temperature programmed laboratory oven, a stainless steel wire mesh cube, NiCr/NiAl thermocouples and a temperature recording device as described in EC A.16.
Based on the results obtained the test item is considered ‘not self-ignitable’.
Reference
An exothermic effect of the test item by self-heating was observed at an oven temperature of 20°C. During this effect the test item reached a temperature of 46°C. Between 150 and 200°C, temperature of the sample differed slightly from the oven temperature. No explanation is available for this.
According to the guideline, a test item is self-ignitable when the sample temperature reaches 400°C by self-heating. Since this was not observed during the entire experiment, the test item is considered ‘not self-ignitable’.
After the experiment, the test item in the cube was unchanged. The container that was placed below the cube had white scale with solid drops. It indicated that the test item had decomposed and/or reacted during the experiment.
