Remarks on result:
other: equivalent to >482.2°C

No self-ignition observed up to the melting point

Conclusions:
Under the study conditions, the relative self-ignition temperature of the test substance was determined to be >482.2°C.
Executive summary:

A study was conducted to determine the auto flammability of solids of the substance, according to ASTM method E659. Under the study conditions, the relative self-ignition temperature of the test substance was determined to be >482.2°C (Fackelman, 2019).

Description of key information

The relative self-ignition temperature was determined according to ASTM Method E659 (Fackelman, 2019).
