Scope: This standard specifies a method for the determination of fluid permeability of permeable sintered metal materials (the pores of which are continuous or interconnected). The tests are carried out in cases where fluid permeability can be expressed by viscous and inertial permeability coefficients (see Appendix A). This standard does not apply to slender tubular samples, because the pressure drop of the fluid through the direction of the inner hole of the tubular sample is not negligible compared with the pressure drop of the fluid through the wall thickness of the tubular sample (see Appendix A.5).
