ISO 13317-4:2014规定了通过重力作用下在液体中沉降的颗粒质量来确定颗粒尺寸分布的方法。该方法基于直接质量测量，给出了等效球形颗粒直径的质量分布。通常情况下，重力液体沉降法适用于1μm至100μm尺寸范围内的样品，且满足颗粒雷诺数小于0.25的沉降条件。

ISO 13317-4:2014 specifies the method for the determination of particle size distribution by the mass of particles settling under gravity in liquid. This method is based on a direct mass measurement and gives the mass distribution of equivalent spherical particle diameter. Typically, the gravitational liquid sedimentation method applies to samples in the 1 μm to 100 μm size range and where the sedimentation condition for particle Reynolds number less than 0,25 is satisfied.
