Applicant's summary and conclusion

Conclusions:
The test item is a not self heting substance
Executive summary:

The substance and a 1:1 mixture with kieselgur was tested in the Grewer oven for self heating properties according to VDI 2263 sheet 1. The pure substance showed self heating at 330°C and the 1:1 mixture at 320°C.
