Conclusions:
The autoignition temperature of HFE s-601 is 400 °C (EU A.15)
Executive summary:

In a test of HFE s-601 done per EU test method A.15 and DIN 51794, the lowest observed autoignition temperature was 404 °C. This value was rounded down to 400 °C per DIN 51794 practice. The study was conducted in accordance with accepted guidelines and was GLP compliant; therefore the study is considered reliable without restrictions.
