ISO 18754:2003
Fine ceramics (advanced ceramics, advanced technical ceramics) — Determination of density and apparent porosity
ISO 18754:2003 specifies a method for the determination of the apparent solid density, bulk density and apparent porosity of fine ceramics.
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 may not be satisfactory. The method may also not give satisfactory open porosity result if it is less than 0,5 %.
