Applicant's summary and conclusion
- Conclusions:
- The substance has not to be clssified as self heating substance acoording to UN-transportation classification and EU-GHS/CLP
- Executive summary:
When testing the pure substance for self-ignition according to VDI 2263 sheet 1 in a 8 ml wire basket (Grewer oven) endothermic behaviour was observed starting at 220°C. No exothermic behaviour could be measured up to 450 °C.
A 1:1 mixture of the substance with kieselgur showed also endothermic behavior at about 220 °C and additionally starting at about 240°C exothermic behaviour that resulted in an increase of temperature up to 500 °C
