Applicant's summary and conclusion

Conclusions:
The substance has not to be classified as
self heating substance (class 4.2) acc. to UN transport classification and EU-GHS/CLP (EG 1272/2008)
Executive summary:

The substance was tested for self-ignition according to VDI 2263 sheet 1 using the Grewer-oven (8ml wire basket). For the pure substance no self ignition was observed up to the maximum test temperature of 440°C (since the substance had melted before, the wire basket was empty after reaching the maximum temperature).

When testing a 1 : 1 mixture with kieselgur the first exothermic effect was observed at about 270°C, but the temperature of the reference was not exceeded. A second exothermic effect was observed at 320 °C that resulted in a temperature increase up to about 450°C
