The work of preparing International Standards is normally carried out throughIsotechnicalcommittees.Eachmemberbodyinterestedinasubjectforwhichatechnical 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. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives) Attention is drawn to the possibility that some of the elements of this document may be the subject 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 constituteanendorsement. For an explanation on 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 the following URL: www.iso.org/iso/foreword.html. The committee responsible for this document is Iso/TC 261, Additive manufacturing in cooperation with ASTM F42, Additive Manufacturing Technologies, on the basis of a partnership agreement between ISO and ASTM International with the aim to create a common set of ISO/ASTM standards on additive manufacturing. iv @ IS0/ASTM International 2017 - All rights reserved
