Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- from 2020-06-02 to 2020-06-24
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: VDI 2263, sheet 1, GrewerOven
- Version / remarks:
- 1990
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: UN Manual of Tests and Criteria, Appendix 6 Screening Procedures, Division 4.2: Substances which may be liable to spontaneous combustion
- Version / remarks:
- 7th edition, 2019
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Key result
- Relative self-ignition temperature:
- ca. 190 °C
- Conclusions:
- The pure test item indicated a self-ignition at atmospheric pressure starting at a temperature of approx. 190 °C.
- Executive summary:
A study according to UN Manual of Tests and Criteria, Devision 6.2 and VDI 2263, sheet 1 was performed to investigate the relative self-ignition of the test item. 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. The temperature of the oven was increased with a constant heating rate (1.2 K/min) in an air stream of 100 to 120 L per hour and tho temperature of the sample was recorded as a function of time at intervals of 10 seconds. The self-ignition behavior of the pure test item was indicated as a deviation between sample temperature and reference temperature.
In the investigation of self-ignition in the Grewer Oven for the pure test item first a small endothermic effect could be observed at a temperature of 140 °C which results into an exothermic effect at approx. 190 °C. This effect leads to a temperature increase up to 550 °C (corresponding temperature of the reference material 227 °C). A black residue remained in the wire basket after the test. The relative self-ignition of the test item was determined to be at ca. 190 °C.
Reference
In the investigation of self-ignition in the Grewer Oven for the pure test item first a small endothermic effect could be observed at a temperature of 140 °C which results into an exothermic effect at approx. 190 °C. This effect leads to a temperature increase up to 550 °C (corresponding temperature of the reference material 227 °C). A black residue remained in the wire basket after the test.
For the test item in mixture with Kieselguhr a weak exothermic effect could be observed starting at a temperature of approx. 180 °C which led to a temperature increase up to 310 °C (corresponding temperature of the reference material 290 °C). A grey residue remained in the wire basket after the test.
