Scope

This second edition cancels and replaces the first edition (i. e. ISO 4022:1977). The test is carried out under such conditions that the fluid permeability can be expressed in terms of viscous and inertia permeability coefficients (see annex A). Does not apply to very long hollow cylindrical test pieces of small diameter. Annex B gives test fluids.
