Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018-06-15 to 2018-06-18
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- EU Method A.16 (Relative Self-Ignition Temperature for Solids)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- No self-ignition could be observed up to the maximum oven temperature of 400 °C.
- Executive summary:
A study was conducted according to VDI 2263, part 1 1990, test methods for the determination of the safety characteristics of dusts; UN Transport Regulations, Appendix 6, Screening Procedures (Substances which may be liable to spontaneous combustion (Division 4.2)) to determine the self-ignition temperature of the test item. For this purpose, the test item was filled in a small wire basket of a volume of 8 cm3 and this wire-basket was placed into the oven. In this oven, the self-ignition behavior of five samples can be determined simultaneously.An additional basket was filled with a reference material (graphite). No self-ignition could be observed up to the maximum oven temperature of 400 °C.
Reference
In the investigation of self-ignition in the Grewer Oven for the pure test item a slight endothermic process was detected starting at approx.50 °C. After the test, the test item in the wire basket was a black mass. No self-ignition could be observed up to the maximum oven temperature of 400 °C.
