Key result
Relative self-ignition temperature:
ca. 184 °C
Remarks on result:
preliminary test
Under the study conditions, relative self-ignition temperature of the test substance was observed at 184 °C.
Executive summary:

A study was conducted to determine self ignition temperature of the test substance according to EU Method A.16. A specific amount of the test substance is placed in an oven, in a wire-mesh cube at room temperature; the temperature difference/time curve of the sample of test substance is recorded while the temperature of the oven is increased to 400°C at a rate of 0.5°C/min. For the purpose of this test, the temperature of the oven at which the sample temperature reaches 400°C by self-heating is called the self-ignition temperature. Three replicate tests were performed. Under the study conditions, relative self-ignition temperature of the test substance was observed at 184 °C.
