Any other information on results incl. tables

Additionally, a Differential Thermal Analysis (DTA) measurement was conducted with a 4.0 mg sample in an open glass crucible at 20 bar air pressure with a heating rate of 3 K/min. Self-heating started at 310 °C (high peak at 350 °C). Oxidation started after decomposition.

Applicant's summary and conclusion

Conclusions:
The test substance shows self-heating in the Grewer oven at 310 °C. Therefore, the test material is not a self-heating substance class 4.2 according to dangerous goods regulations.
Executive summary:

Self-ignition of the test substance was determined by a screening test in the Grewer oven. The test substance shows self-heating at 310 °C.
