Testing of carbonaceous materials - Determination of bulk density by buoyancy method and the open porosity by impregnation with water - Solid materials
The method is used for the determination of the bulk density by buoyancy method, measured in g/cm<(hoch)3>, and the open porosity by impregnate with water, measured as volume fraction in %, of carbon and graphite materials (solid materials).
