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 liaison with ISO, also take part
in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all
matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for
the different types of ISO documents should be noted (see www.iso.org/directives).
ASTM International is one of the world’s largest voluntary standards development organizations
with global participation from affected stakeholders. ASTM technical committees follow rigorous
due process balloting procedures.
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and ASTM International shall not be held responsible for identifying any or all
such patent rights. Details of any patent rights identified during the development of the document
will be in the Introduction and/or on the ISO list of patent declarations received
(see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does
not constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT),
see www.iso.org/iso/foreword.html.
This document was prepared by ASTM Committee F42, Additive Manufacturing Technologies (as
ASTM F3303‐2018), and drafted in accordance with its editorial rules. It was assigned to Technical
Committee ISO/TC 261, Additive manufacturing, and adopted under the “fast‐track procedure”.
Any feedback or questions on this document should be directed to the user’s national standards
body. A complete listing of these bodies can be found at www.iso.org/members.html.
