Carbonaceous materials used in the production of aluminium — Baked anodes and cathode blocks — Part 2: Determination of apparent density and of open porosity using a hydrostatic method

This document specifies a hydrostatic method for the determination of the apparent density and the open (to water) porosity of carbonaceous products used in the production of aluminium. This hydrostatic method was developed principally to determine the open porosity but can also be used to measure the apparent density. This document is especially applicable to samples of complex on irregular geometry (due to drilling difficulties).
