标准摘要
[中文适用范围]： 本文件规定了在标准化条件下测定金属粉末表观密度的漏斗法。 该方法适用于自由流经直径 2.5 mm 孔口的金属粉末。 然而，它可用于难以流过 2.5 mm 直径孔口但可流过 5 mm 直径孔口的粉末。 ISO 3923-2[1] 中规定了测定不会流过直径 5 mm 孔的粉末表观密度的方法。 [外文原描述]： This document specifies the funnel method for the determination of the apparent density of metallic powders under standardized conditions. The method is intended for metallic powders that flow freely through a 2,5 mm diameter orifice. It can, however, be used for powders that flow with difficulty through a 2,5 mm diameter orifice but flow through a 5 mm diameter orifice. Methods for the determination of the apparent density of powders that will not flow through a 5 mm diameter orifice are specified in ISO 3923‑2 [1] .
