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

is used for petroleum coke specifications, whereas 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.
