Applicant's summary and conclusion

Conclusions:
The substance was heated up to 400°C. There were no signs of self-ignition or self-heating when the test item was held at 140°C for 24 hours. When the test item was heated between 140 and 400°C self-heating occured at 265°C.
Executive summary:

In a GLP-compliant, guideline test the substance was heated up to 400°C. There were no signs of self-ignition or self-heating when the test item was held at 140°C for 24 hours. When the test item was heated between 140 and 400°C self-heating occured at 265°C.
