Applicant's summary and conclusion
- Conclusions:
- The substance has not to be classified as autoflammable according to EG 1272/2008 and to the transport classification
- Executive summary:
The substance was tested for autoflammability according to VDI 2263 sheet 1 (screening in the Grewer oven). The pure substance showed selfignition starting with 230 °C. The 1:1 mixture with kieselgur had a selfignition at about 250°C
