Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in li aison with ISO, also ta ke part in th e work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
Draft International Standards adopted by the technical committees are circulated to the member bodies for
voting. Publication as an International Standard requires approval by at l east 75% of the member bodies
casting a vote.
Attention is drawn to t he possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/ASTM 52915 was prepared by ASTM Internati onal (as ASTM F2915) and was adopted, under a special
“fast-track procedure”, by Technical Committee ISO/TC 261, Additive manufacturing, in parallel with its
approval by the ISO m ember bodies. This has been done under a P artner Standards Development
Organization (PSDO) agreement on cooperation between ISO/TC 261, Additive manufacturing, and ASTM
International committee F42, Additive Manufacturing.
