Gives the procedure for measuring the permeability to gases of dense shaped refractory products, i.e., measurement of the property by which the material allows a gas to pass through it when under a difference of pressure. The determination is generally made by the passage of air. The method described in this Section takes account of the dynamic viscosity of the gas.
