Applicant's summary and conclusion
- Conclusions:
- The substance has not to be classified 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) a stepwise self-ignition starting from 225 °C that resulted in an increase in temperature up to about 550°C.
A 1:1 mixture of the substance with kieselgur showed self-ignition at about 215 °C that resulted in an increase of temperature up to 600 °C
