FAQ
What standards and norms apply to the quality of metal powders?
The quality of metal powders for additive manufacturing is regulated by various standards and norms that define the requirements and test methods for the characterization of metal powders. Some of the most important standards and norms are
DIN EN ISO/ASTM 52907:2020-05: Additive manufacturing - Base materials - Methods for characterization of metal powders. This standard covers the documentation, traceability, sampling, particle size distribution, chemical element composition, density, morphology and flowability of metal powders.
DIN EN ISO 3953:2011-05: Metal powders - Determination of tap density. This standard describes the method for determining the tap density of metal powders, which is a measure of the packing density and porosity of the powders.
DIN EN ISO 4490:2008-12: Metal powders - Determination of particle size distribution by sieve analysis. This standard describes the method for determining the particle size distribution of metal powders by sieving, which influences the particle size and particle shape of the powders.
