Metallic powders - Determination of apparent density - Part 1: Funnel method
Published By:International Organization for Standardization (ISO)
This part of ISO 3923 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 may, 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.
