Any other information on results incl. tables

In the Grewer screening with the pure test substance, self-heating was observed at 280 °C with a tenperature rise to 360 °C.

A 1:1 mixture of the test substance with Kieselguhr showed also self-heating starting from 280 °C, with a temperature rise to 650 °C.

Applicant's summary and conclusion

Conclusions:
The test substance shows self-heating at 280 °C. 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 280 °C.
