Metallic powders - Determination of apparent density - Part 1: Funnel method (ISO 3923-1:2018); German version EN ISO 3923-1:2018
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.
