This European Standard specifies a method for the measurement of the permeability to
gases of dense, shaped refractory products.
Note : The method specified takes account of the dynamic viscosity of the gas,
and therefore the results obtained may not be directly comparable with those
obtained by earlier methods which took no account of viscosity. The
determination is generally made by the Passage of ak. Other gases may be used
when required and the viscosities of air and nitrogen are given.
