Advanced technical ceramics. Ceramic composites. Physical properties. Determination of density and apparent porosity Ingestion-build-202139 PD IEC TR 61948‑4 isWhat is BS EN 1389 Density and porosity of ceramics about? BS EN 1389 is a European Standard that describes two methods for the determination of the bulk density and open porosity of ceramic matrix composites with fibrous reinforcement. Two methods are described and are designated as Methods A and B, as follows: Method A: determination of bulk density only by measurement of dimensions and mass Method B: determination of bulk density and open porosity
