Fine ceramics (advanced ceramics, advanced technical ceramics) — Determination of density and apparent porosity
Two methods are described and are designated as Methods A and B, as follows:
— Method A: Determination of bulk density, apparent solid density and apparent porosity by liquid displacement (Archimedes' method).
NOTE 1 This method is not appropriate for the determination of an apparent porosity greater than 10 %. For materials with higher porosity, the accuracy of the measurement might not be satisfactory. This method might also not give a satisfactory open porosity result if it is less than 0,5 %.
NOTE 2 This method is also not suitable for materials which are known to have an average pore size of greater than 600 µm.
— Method B: Determination of bulk density only, by measurement of geometric dimensions and mass.
