BS ISO 21687:2007

Carbonaceous materials used in the production of aluminium. Determination of density by gas pyknometry (volumetric) using helium as the analysis gas. Solid materials. | Status: Current, Confirmed

1 Scope This International Standard specifies a method for the determination of the density of green and calcined petroleum coke and similar solid materials (e.g. electrodes). This standard is also suitable for hydrocarbons with a high-temperature boiling range and for other solid materials. This method is not suitable for graphitized material.
