Control of cleanliness of metal powder feedstock used in Additive Manufacturing (AM) processes is essential to ensure quality of final AM components. This standard is needed to guide users of metal powders for AM on identification and selection of test methods suitable for detecting, quantifying and classifying contamination. The standard will be used by users of AM machines to allow them to perform cleanliness assessment of unused powders and re-used powders.
