Results and discussion
Any other information on results incl. tables
Results
In the investigation of self-ignition in the Grewer Oven for the pure test item an exothermic process was detected from above 200 °C, which led to a maximum temperature of approx. 650 °C (395 °C above the corresponding temperature of the reference material). A black grey residue remained in the wire basket after the test.
For the test item in mixture with Kieselguhr also an exothermic process was detected from above 200 °C, which led to a maximum temperature of approx. 645 °C (360 °C above the corresponding temperature of the reference material).
Table 1 summarises the results of the Grewer Oven experiment.

Applicant's summary and conclusion
- Interpretation of results:
- Category 2 (self-heating substances and mixtures) based on GHS criteria
- Conclusions:
- Final Results / Classification:
The pure test item indicated self-ignition at atmospheric pressure starting at a temperature of 200 °C. 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 of the results of the tests on the self-ignition in the Grewer Oven the test item is classified as follows:
UN Transport Regulation: The test item is not classified as self-heating substance in class 4, division 4.2 according to the UN Transport Regulation, if the test item is handled in containers with a volume of < 3 m³.
If the test item is handled in containers > 3 m³ it is classified as self-heating substance in class 4, division 4.2 and assigned to packing group III.
GHS / CLP Regulation EC 1272/2008 Annex 1: 2.11: The test item is not classified as self-heating substance according to GHS/CLP Regulation EC 1272/2008 Annex 1: 2.11, respectively, if the test item is handled in containers with a volume of < 3 m³.
If the test item is handled in containers > 3 m³, it must be classified as a self-heating substance and assigned to category 2. - Executive summary:
