It defines an ignition temperature method for the determination of the reactivity to air of calcined petroleum coke used in the manufacture of anods for the production of aluminium. A heating rate of 5 Degree C/min is used for petroleum coke specifications, whereas 10 Degree C/min is used for statistical process control of calcination kilns and for anode butt quality control.

This part of ISO 12982 describes an ignition temperature method for the determination of the reactivity to air of calcined petroleum coke used in the manufacture of anodes for the production of aluminium. A heating rate of 5 °C/min is used for petroleum coke specifications, whereas 10 °C/min is used for statistical process control of calcination kilns and for anode butt quality control.

NOTE ISO 12982-2 (in preparation) will give a thermobalance method for the determination of the reactivity to air of calcined coke.
