This second edition cancels and replaces the first edition (i. e. ISO 3923:1977). 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 freely through a 5 mm diameter orifice. Methods for powders that will not flow through a 5 mm diameter orifice are specified in parts 2 and 3.
