标准摘要
[中文适用范围]： 本文件规定了一种测定可渗透烧结金属材料的流体渗透性的方法，其中孔隙故意连续或互连，在流体渗透性可以用粘性和惯性渗透性系数表示的条件下进行测试（见附录 A）。 本文件不适用于非常长的小直径空心圆柱体试件，其中流体沿圆柱体孔流过的压降与流体流过壁厚的压降相比可能不可忽略（见 A.5)。 [外文原描述]： This document 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). This document does not apply to very long hollow cylindrical test pieces of small diameter, in which the pressure drop of the fluid in passing along the bore of the cylinder might not be negligible compared with the pressure drop of the fluid passing through the wall thickness (see A.5).
