Significance of porosity.—This is briefly outlined. Standard reference method.—The requirements of an engineering testing method are simplicity, rapidity and convenience with no more accuracy than practical considerations justify. There should, however, be also available a standard reference method , that is, a laboratory method where accuracy is the main requirement. Types of pores.—Six types of pores are described and the process of absorption under various conditions is analyzed. Defitions.—Definitions are proposed for the terms, permeability, penetrability, absorptivity, porosity. bulk density, closed‐pore space and “cracks” and “holes,” and methods of measurement are suggested.
