BS 6043-2.13:1996

This standard BS 6043-2.13:1996 Methods of sampling and test for carbonaceous materials used in aluminium manufacture. Electrode coke is classified in these ICS categories:

• 75.160.10 Solid fuels
• 71.100.10 Materials for aluminium production

This lnternational Standard specifies a method for the measurement of the bulk density of granular carbon and graphite materials used in the manufacture of carbon electrodes for the production of aluminium.

Bulk density depends on the size, shape and porosity of the granules. For samples with similar grain size and shape, comparison of the real density with the bulk density (tapped) allows the porosity to be assessed. Coke porosity is an important quality parameter which can affect the quality and performance of the carbon electrodes.
