The paper deals with one of the technological properties of metal powders, such as tap density. The objective is to analyze the state standard in force for determining the density of metal powders after tapping, taking into account operational experience in the field of powder metallurgy. It is established that the methods identified in the standard for determining the density of metal powders have contradictions and discrepancies. A simple and reliable device is proposed and manufactured for mechanical tapping of powders.
