Any other information on results incl. tables

The test item contains a residual moisture of 0.1 weight-% which was determined by drying the test item under vacuum.

In the investigation of self-ignition in the Grewer-oven for the pure test item and for the test item in mixture with Kieselghur an endothermic process was detected at 100 °C, which is allocated to the melting of the test item. For the pure test item no exothermal effect is detected up to the maximum temperature of about 400 °C. After the measurement the basket of the pure test item is empty. The complete test item flowed out of the basket. The test item in mixture with Kieselghur indicated a low exothermal effect at 180 °C, which lead only to a small temperature increase of about 20 °C. At 290 °C and 370 °C two additional exothermal effects were detected, which lead to a temperature increase of about 60 °C each.

Applicant's summary and conclusion

Conclusions:

The product has neither to be classified as self-heating substance in Division 4.2 according to the UN-Transport regulation nor as self-heating
substance according to GHS.
The test item has no self-ignition temperature according to EC 440/2008, Annex V, Part A, A.16. up to the melting of the test item or the
maximum temperature of 400 °C, respectivety.

Executive summary:

The study was performed according to EC 440/2008, Method A.16, Relative Self-Ignition Temperature for solids and VDI 2263, sheet 1, Grewer-Oven in year 2010.

The pure product melted at 100°C and flow completely out of the basket. The product in mixture with Kieselghur indicates a self- ignition starting at 180 °C.

The product has neither to be classified as self-heating substance in Division 4.2 according to the UN-Transport regulation nor as self-heating substance according to GHS. The test item has no self-ignition temperature according to EC 440/2008, Annex V, Part A, A.16. up to the melting of the test item or the maximum temperature of 400 °C, respectivety.
