Applicant's summary and conclusion

Conclusions:
The substance shows no autoflammability.
Executive summary:

The substance was tested for autoflammability according to VDI 2263 sheet 1 (screening in the Grewer oven). The pure substance showed no selfignition up to 400 °C. The 1:1 mixture with kieselgur had a selfignition at about 290°C
