Density and Porosity of Dense Shaped Refractory Products - Test Method - BS EN 993-1:1995, BS 1902-3.8:1995
Methods of test for dense shaped refractory products. Determination of bulk density, apparent porosity and true porosity.
The bulk density is the ratio of the mass of the dry material of a porous body to its bulk volume.
The mass of a dry test piece of a specified geometrical form is determined by weighing and the dimensions are measured. From these values and from the true density of the material, the volume, bulk density and true porosity are determined by calculation.
