ISO 12982-1:2000
Carbonaceous materials used in the production of aluminium — Calcined coke — Determination of the reactivity to air — Part 1: Ignition temperature method
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.
