Any other information on results incl. tables

The Grewer oven screening shows self-heating at 290 °C.

The hot storage test at 198 °C shows:

Maximum temperature: 201.2 °C (sample warming: 3.2 °C)

Time to temperature equalisation: 7 h

Time from temp. equalisation to max. temp.: 8 h (479 min).

Applicant's summary and conclusion

Conclusions:
The test substance shows self-heating at 290 °C in the Grewer oven. The hot storage test at 198 °C shows sample warming to 201.2 °C. The test substance is not self-heating.
Executive summary:

Self-ignition of the test substance was determined by a screening test in the Grewer oven and by a hot storage test at 198 °C (1 L wire mesh basket, sample weight 310 g, test duration 23 h). The test substance shows self-heating at 290 °C in the Grewer oven. The hot storage test at 198 °C shows sample warming to 201.2 °C. The test substance is not self-heating.
