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. 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
patent rights. ISO 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.
The committee responsible for this document is ISO/TC 261, Additive manufacturing, in cooperation with
ASTM Committee 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.
This document cancels and replaces the first edition (ISO 17296-3:2014), which has been technically
revised and merged with document ASTM F3122-14 Standard Guide for Evaluating Mechanical
Properties of Metal Materials Made via Additive Manufacturing Processes and therefore re-designated
and renamed to ISO/ASTM 52927 Additive manufacturing — General principles — Main characteristics
and corresponding test methods
The main changes compared to the previous edition are as follows:
— The main types of materials (metallic, polymers and ceramics) are separated in specific Annexes
following the main part containing general requirements,
— This version includes the contents of ASTM F3122-14 Standard Guide for Evaluating Mechanical
Properties of Metal Materials Made via Additive Manufacturing Processes and merges them with
(formerly) ISO 17296-3.

Introduction
Additive manufacturing is a process of joining materials to make parts from 3D model data, usually
layer upon layer, as opposed to subtractive manufacturing and formative methodologies. It is used to
manufacture prototypes and production parts.
This document aims to offer recommendations and advice to machine manufacturers, feedstock
suppliers, AM system users, part providers, and customers, to improve communication between these
stakeholders concerning test methods.
This document has been developed within a set of consistent documents from terminology to test
methods and data exchange.
Additive manufacturing processes require the selective application of thermo-physical and/or chemical
mechanisms to generate the part. Thus, it is possible to produce parts with different characteristics,
depending on the method and the process parameters used. However, complete testing of all
characteristics for every part is neither cost-effective nor technologically feasible. Therefore, when
formulating parts specifications, the nature and scope of testing is an important issue.
This document provides an overview of test methods for the characterization of the mechanical
properties of metals, ceramics and polymers. It lists all the applicable standards based on specimens
manufactured in a traditional process and gives the complement applicable when these specimens are
manufactured by additive manufacturing.
At the time of publication of this document, the state of the art does not allow to describe all these
specificities related to additive manufacturing. This document will therefore be regularly revised in
order to incorporate the knowledge acquired in the field of additive manufacturing.
