Link to relevant study record(s)
- Endpoint:
- relative self-ignition temperature (solids)
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- 2018-05-16 to 2018-08-23
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- other: VDI 2263 (1990), sheet 1, Grewer Oven
- Version / remarks:
- 1990
- Deviations:
- no
- Qualifier:
- according to guideline
- Guideline:
- other: see 'Version / remarks'
- Version / remarks:
- UN Recommendations on the TRANSPORT OF DANGEROUS GOODS: Manual of Tests and criteria, Rev. 6 (2015) and UN-Model Regulations, Rev. 20 (2017)
- Deviations:
- no
- GLP compliance:
- yes (incl. QA statement)
- Relative self-ignition temperature:
- > 270 °C
- Conclusions:
- The pure test item indicated a multi-stage self-ignition at atmospheric pressure starting at a temperature of 270 °C without a significant temperature increase. Due to the high onset temperature in the Grewer Oven, it can be assumed that the UN Test N.4 using the 25 mm cube sample at 140 °C is negative.
- Executive summary:
The study was conducted under GLP-conditions and in accordance with VDI 2263 sheet 1 Grewer Oven (1990) and according to UN Recommendations on the TRANSPORT OF DANGEROUS GOODS: Manual of Tests and Criteria, Rev. 6 (2015) and UN-Model Regulations, Rev. 20 (2017).
The pure test item indicated a multi-stage self-ignition at atmospheric pressure starting at a temperature of 270 °C without a significant temperature increase. Due to the high onset temperature in the Grewer Oven, it can be assumed that the UN Test N.4 using the 25 mm cube sample at 140 °C is negative.
On the basis to the results of the tests on the self-ignition in theGrewer Oventhe test item is classified as follows:
UN Transport Regulation: The test item has not to be classified asself-heating substancein class 4, division 4.2 according to the UN Transport Regulation.
GHS / CLP Regulation EC 1272/2008 Annex 1: 2.11: The test item has not to be classified asself-heating substanceaccording to GHS/CLP RegulationEC 1272/2008 Annex 1: 2.11.
