303-12 What should be paid attention to in the sample pretreatment for the determination of fluidity of metallic powder?
 
Metallic powders are generally tested in receiving state.
In some cases, the powder can be dried.
However, if the powder is easily oxidized, drying should be carried out in a vacuum or in an inert atmosphere.
If the powder contains volatile substances, it is not allowed to dry.
