BS 6043-2.21.1:2001

This standard BS 6043-2.21.1:2001 Methods of sampling and test for carbonaceous materials used in aluminium manufacture. Electrode coke. Air reactivity of calcined coke is classified in these ICS categories:

• 75.160.10 Solid fuels
• 71.100.10 Materials for aluminium production

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.
