Applicant's summary and conclusion

Conclusions:
The test substance shows self-heating at 250 °C. Negative hot storage test at 200 °C. The test substance is not self-heating according to UN class 4.2.
Executive summary:

Self-ignition of the test substance was determined by a screening test in the Grewer oven. The test substance shows weak self-heating above 250 °C. A hot storage test at 200 °C (1 L wire mesh basket, 64 h test duration) revealed sample heating of 2.8 °C. The test substance is not self-heating.
