Study performance

The cube is filled with the substance to be tested and is tapped gently, adding more of the substance until the cube is completely full.

The cube is then suspended in the center of the oven at room temperature.

One thermocouple is placed at the center of the cube and the other between the cube and the oven wall to record the oven temperature.

The temperatures of the oven and sample are continuously recorded while the temperature of the oven is increased to 400°C, or to the melting point if lower, at a rate of 0.5°C/min.

When the substance ignites the sample thermocouple will show a very sharp temperature rise above the oven temperature

Conclusions:
Reactive Red 45:1 showed relative self-ignition temperature 258.9 °C.
Executive summary:

The relative self-ignition temperature for solids of test substance, Reactive Red 45:1, was determined.

The procedure was performed according to the Method A.16. Relative self-ignition temperature for solids,Council Regulation (EC) No.440/2008, Published in O.J. L 142, 2008
