- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- July 1st, 2019
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: Recommendations on the TRANSPORT OF DANGEROUS GOODS: Manual of Tests and Criteria, 6th edition, New York and Geneva, 2015: Appendix 6 Screening Procedures, Division 4.2: Substances which may be liable to spontaneous combustion
- Version / remarks:
- 2015
- Qualifier:
- according to guideline
- Guideline:
- other: VDI 2263, sheet 1, Grewer Oven
- Version / remarks:
- 1990
- GLP compliance:
- no
- Remarks on result:
- no self ignition observed under the test conditions
- Conclusions:
- The pure test item indicated no self-ignition at atmospheric pressure in the Grewer Oven. Therefore, it can be assumed that the UN test N.4 using the 25 mm cube sample at 140 °C is negative. On the basis of the tests on the self-ignition in the Grewer Oven, the test item is classified as follows:
UN Transport Regulation: ttest item is not classified as self-heating substance in class 4, division 4.2.
CLP Regulation (EC 1272/2008) Annex 1: 2.11: test item is not classified as self-heating substance.
- Executive summary:
The self-ignition behavior of the test item was determined in the oven according to VDI 2263, sheet 1. 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).
The pure test item indicated no self-ignition at atmospheric pressure in the Grewer Oven. Therefore, it can be assumed that the UN test N.4 using the 25 mm cube sample at 14 0°C is negative. On the basis of the tests on the self-ignition in the Grewer Oven the test item is classified as follows:
UN Transport Regulation: test item is not classified as self-heating substance in class 4, division 4.2.
CLP Regulation (EC 1272/2008) Annex 1: 2.11: test item is not classified as self-heating substance.
Reference
In the self-ignition in the Grewer Oven for the pure test item an endothermic effect was detected starting at a temperature of approx. 150 °C. A black residue remained in the wire basket after the test. For the test item in mixture with Kieselguhr, an endothermic effect was detected starting at a temperature of approx. 150 °C. An exothermic effect was observed starting at a temperature of approx. 240 °C which produced a first maximum temperature of 360 °C and led to an ultimate maximum temperature of approx. 430 °C. This test result is not relevant for the classification regarding self-ignition of the test item.

Additional information
No self ignition in the Grewer oven test run according to VDI 2263, sheet 1. Therefore, it can be assumed that the UN test N.4 using the 25 mm cube sample at 140°C is negative.
Test item is classified as follows:
UN Transport Regulation: test item is not classified as self-heating substance in class 4, division 4.2.
CLP Regulation (EC 1272/2008) Annex 1: 2.11: test item is not classified as self-heating substance.
