NF EN ISO/ASTM 52924, E67-024 (08/2023)

This document establishes the classes of part properties required or achievable for additively manufactured polymer parts to provide a common understanding of part quality. It is intended for suppliers of polymer part manufacturing services that use additive manufacturing machines and for customers of these services. Part designers as well as buyers and manufacturing service providers can specify, in a traceable manner, the level of part properties required or achievable using this document. The classification is based on mechanical, physical and geometric properties. Other properties may be defined between the buyer and the manufacturing service provider. This document applies to parts that have been manufactured from a thermoplastic polymer by thermal material fusion reaction typically achieved by powder bed fusion (PBF) or material extrusion (MEX) processes. The part property classification applies to parts in manufacturing condition that have been unpacked from the manufacturing space, with all support structures having been removed, but before any post-processing operations. Some industries (e.g. aerospace and medical) typically specify additional requirements.
