This standard is designed to complement the standard ISO/ASTM 52900, which describes different additive manufacturing processes using a variety of materials. This standard covers the testing of components manufactured from metallic materials using additive technologies. As with conventional manufacturing processes (e.g. casting and milling), metallic parts produced by additive manufacturing technologies have critical-to-quality characteristics. These include in particular density, strength, hardness, surface quality, dimensional accuracy, residual stresses, absence of cracks, voids and structural homogeneity, which are typically tested in additively manufactured components. The quality of additively manufactured components is essential if functional components are produced on an industrial scale. Thus, it is necessary to qualify additive manufacturing processes according to uniform criteria and to apply standardized in-process and post-process testing. Once approved, this standard will have the designation ISO/ASTM 52908.
The title and scope are in draft form and are under development within this ASTM Committee.
