BS EN ISO 4022:2018规定了一种测定可渗透烧结金属材料流体渗透性的方法，其中孔隙率有意连续或相互连接，测试条件是流体渗透性可以用粘性和惯性渗透系数表示（见附录a）。交叉引用:ISO 2738购买本文件时提供的所有现行修订均包含在购买本文件中。

BS EN ISO 4022:2018 specifies a method for the determination of the fluid permeability of permeable sintered metal materials in which the porosity is deliberately continuous or interconnecting, testing being carried out under such conditions that the fluid permeability can be expressed in terms of viscous and inertia permeability coefficients (see Annex A).Cross References:ISO 2738All current amendments available at time of purchase are included with the purchase of this document.
