Significance and Use
4.1 The overall aim of this guide is to provide quality guideline data for powder test methods commonly used for characterizing metal powder feedstock used in AM.
4.2 These guidelines are intended for users of powder characterization test methods, to provide guidance on expected test data variability, when developing standard operating procedures for test methods in-house, and when approving laboratory data from in-house powder testing.
4.3 These guidelines are intended for users of powder characterization test method data, to give an indication of the levels of test data variability that can be obtained from different laboratories, when approving and using test data from external laboratories.
4.4 This guide considers powder test methods that could be used to characterize metal powder feedstock used in Powder Bed Fusion (PBF), Binder Jetting (BJT), and Directed Energy Deposition (DED) processes. This guide does not consider methods to examine or assess the binder-powder formulation in BJT.
Scope
1.1 This guide provides:
1.1.1 Quality assessment guidelines on currently active ASTM International, and selected International Organization for Standardization (ISO) powder test methods, for metal powder feedstock used in additive manufacturing (AM).
1.1.2 Characterization data for AM grade metal powders; both within laboratory and interlaboratory study data, for the purpose of comparative quality evaluation of the data.
1.1.3 A description of the most commonly used powder test methods and references to their associated standard documents.
1.1.4 Best practice guidance on how to apply the aforementioned powder test methods, to make them more suited for AM metal powder characterization.
1.2 Units—The values stated in SI units are to be regarded as the standard. No other units of measurement are included in this standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
