Conclusions:

According to EU Method A.16, the relative self-ignition temperature of Everzol SR98 was not detected.

Executive summary:

This test using the procedures outlined in the ZRICI Study Plan for PCF2019-045-03 and EU Method A.16.Base on the test phenomena and results, the sample temperature could not reach 400°C prior to that of the oven. Therefore, the relative self-ignition temperature ofEverzol SR98 was not detected.
