Applicant's summary and conclusion

Conclusions:
To give a statement for autoflammability additional tests are required
Executive summary:

The substance was tested for autoflammability according to VDI 2263 sheet 1 (screening in the Grewer oven). The pure substance showed selfignition at 140 °C. The 1:1 mixture with kieselgur had a selfignition at about 150°C. Based on this results no claear statement for autoflammabiluity can be given; additonal wire basket tests are required
