Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- Experimental Phase: 09 July 2020 to 10 July 2020.
- Reliability:
- 1 (reliable without restriction)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- yes
- Remarks:
- The test item was heated to 400 °C in the relative self-ignition test which was above the melting temperature of the test item. This deviation is considered to have not affected the integrity or validity of the study.
- GLP compliance:
- yes (incl. QA statement)

- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- The test item has been determined to not have a relative self-ignition temperature below its melting temperature.
- Executive summary:
Introduction
The Relative Self-Ignition Temperature of the substance was assessed using a procedure designed to be compatible with Method A.16 Relative Self-Ignition Temperature for Solids of Commission Regulation (EC) No 440/2008 of 30 May 2008.
Method
Test System
Oven: A temperature programmed laboratory oven with a Eurotherm temperature controller Wire mesh.
Cube: A piece of stainless-steel wire mesh with 0.042 mm openings was cut, folded and secured with wire into an open topped cube with dimensions of 2 x 2 x 2 cm.
Thermocouples: Type K thermocouples Recorder: Graphtec GL200a data logger
Performance of the Test
The cube was completely filled with the test item and placed in the centre of the oven at room temperature. A thermocouple was placed in the centre of the sample and another in the oven. The oven temperature was programmed to increase from ambient to 400 °C (at a rate of 0.5 °C/min. The temperature/time curves relating to the condition in the centre of the sample and the oven were recorded on a data logger. Before and after the test the appearance of the test item was recorded.
Results
The test item was a light brown powder. Whilst heating the test item, no relevant exothermic reaction /self-heating of the sample was been observed. On completion of the test, there was a light grey residue.
Conclusion
The test item has been determined to not have a relative self-ignition temperature below its melting temperature.
Reference
The test item was a light brown powder. Whilst heating the test item, no relevant exothermic reaction /self-heating of the sample was been observed. On completion of the test, there was a light grey residue.
