This International Standard specifies a method for the deter-mination of green strength by measuring the transverse rupture strength of compacts of rectangular cross-section.
Specification for metallic powders - Determination of green strength by transverse rupture of rectangular compacts
This part of ISO 3923 specifies the Scott volumeter method for the determination of the apparent density of metallic powders. It is applicable to powders that will not flow freely through a 5 mm orifice (see ISO 3923/1). Part 3 of this International Standard specifies the oscillating funnel method for the determination of apparent density of such powders, and this is preferred since it gives better preci-sion, but it cannot be used in cases where the powder may change its properties due to the vibration action applied to the powder during testing.
