An apparatus for the measurement of the flow-capillaries radius in rigid porous materials
by the Barus–Bechhold method
A method of measuring the radius of the largest pore in rigid porous materials by the Barus—Bechhold method was described. The scheme and the principle of action of the constructed porosimeter making use of this method was presented. The suitability of the apparatus was illustrated by the results, of determination of the flow-capillaries radius in sintered polystyrene and poly(methyl methacrylate).
