Key result
Remarks on result:
no self-ignition observed up to the melting point
Conclusions:
Three replicate tests were performed. The relative self-ignition temperature of the test item: no ignition was observed up to around 100°C, when the test item melted.
Executive summary:

The purpose of this test is to provide preliminary information on the autoflammability of solid substances at elevated temperatures. 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 item is recorded while the temperature of the oven is increased to the melting of test item (about to 100°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. No relative self-ignition temperature of α,α’-Dichloro-p-xylene was observed up to around 100°C.

Description of key information

No relative self-ignition temperature of α,α’-Dichloro-p-xylene was observed up to around 100°C.

Key value for chemical safety assessment
