Conclusions:
Under the conditions of the test, the test item ignited by self-heating at a temperature of 386°C.
Executive summary:

The relative self ignition temperature of the test item was investigated in an E.U. Method A.16 guideline study. Under the conditions of the test, the test item ignited by self-heating at a temperature of 386°C. At completion of the testing a black pasty solid remained.

The study is a GLP compliant, guideline experimental study, acceptable for assessment of this endpoint.

Description of key information

Under the conditions of the test, the test item ignited by self-heating at a temperature of 386°C. Upon completion of the test a black pasty solid remained.

Key value for chemical safety assessment

Autoflammability / Self-ignition temperature at 101 325 Pa:
386 °C

Additional information

The self-ignition temperature of the test item was determined in a study conducted in accordance with EC Method A.16 and it was found to ignite by self-heating at 386 °C (Dunning 2018).

The study is a GLP compliant, guideline experimental study and is acceptable for assessment of this endpoint.
