Any other information on results incl. tables

The Grewer oven screening showed weak self-heating starting from 270 °C.

When stored at 200 °C, the sample showed weak self-heating and reached a maximum temperature of 208.3 °C 65 minutes after temperature equalisation (which took 2.8 h).

The self-ignition temperature is therefore given as > 200 °C.

Applicant's summary and conclusion

Conclusions:
The substance showed weak self-heating in the Grewer oven screening and in a hot storage test (at 200 °C in a 1 L basket). The test item is not a self-heating substance.
Executive summary:

Self-ignition of the test substance was investigated by a Grewer oven screening and a hot storage test. The Grewer oven screening showed weak self-heating at 270 °C. The hot storage test at 200 °C also revealed very weak self-heating of 8 °C.

The self-ignition temperature is given as > 200°C. The test item is not a self-heating substance.
