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.

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 document was prepared by Technical Committee 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, and in collaboration with the European Committee
for Standardization (CEN) Technical Committee CEN/TC 438, Additive manufacturing, in accordance
with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

ISO/ASTM 52909:2022(E)
Introduction
AM produced metallic parts are being intensively developed and used more widely today with an
expected faster growth in near future. This document aims to support customers’ needs to address
specifics of the AM deposited parts – location and orientation dependent local properties and their
variations over the part or deposition chamber.
This document provides a list of accurate terminologies and existing standards dedicated to mechanical
testing of metallic materials, guidance on designation of coordinate systems and their application to AM
specimens/parts designation, and recommendations on possibilities for local properties measurement.

INTERNATIONAL STANDARD ISO/ASTM 52909:2022(E)
Additive manufacturing of metals — Finished part
properties — Orientation and location dependence of
mechanical properties for metal powder bed fusion
1 Scope
This document covers supplementary guidelines for evaluation of mechanical properties including
static/quasi-static and dynamic testing of metals made by additive manufacturing (AM) to provide
guidance toward reporting when results from testing of as-build specimen or those excised from
printed parts made by this technique or both.
This document is provided to leverage already existing standards. Guidelines are provided for
mechanical properties measurements and reporting for additively manufactured metallic specimen as
well as those excised from parts.
This document does not purport to address all of the safety concerns, if any, associated with its use. It is
the responsibility of the user of this standard to establish appropriate safety, health and environmental
practices and determine the applicability of regulatory limitations prior to use.
This document expands upon the nomenclature of ISO/ASTM 52900 and principles of ISO/ASTM 52921
and extends them specifically to metal additive manufacturing. The application of this document
is primarily intended to provide guidance on orientation designations in cases where meaningful
orientation/direction for AM cannot be obtained from available test methods.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/ASTM 52900 and
ISO/ASTM 52921 apply.

3.1 Definition
3.1.1
part location
location of the part/sample/specimen within the build volume
Note 1 to entry: The part location is normally specified by the x, y, z coordinates for the position of the geometric
centre of the part´s bounding box with respect to the build volume origin.
3.2 Abbreviations
The abbreviations used in this document, and in particular in Figure A.1, are listed in Table 1.
Table 1 — Abbreviations
Abbreviation Signification Comment
S Start Any base of the specimen or part that provides a surface upon which
deposition starts (see Annex A).
E End Any area of a specimen or part that provides a surface upon which the
specimen or part deposition ends (see Annex A).
M Middle Mid-plane of a specimen or part between start and end (see Annex A).
B Both Crack growth captures both start and end of build (see Annex A).
RD Scan direction This may or may not be the same throughout the build (see Annex A).

3.3 Acronyms
The acronyms used in this document for illustrating crack growth directions with respect to the build
direction are listed in Table 2 and illustrated in Figure A.4.
Table 2 — Acronyms
Acronym Signification
XY, YX, XZ, ZX, The first letter represents the direction normal to the crack plane and the second letter repre-
YZ, ZY sents the expected direction of crack extension.
XYB Indicates that crack growth captures both the start and end of the build in XY direction.
XZE Indicates that the crack growth occurs from the end to the start of build in the XZ direction.
XZS Indicates that the crack growth occurs from the start to the end of build in the XZ direction.
YXB Indicates that crack growth captures both the start and end of the build in YX direction.
YZE Indicates that the crack growth occurs from the end to the start of build in the YZ direction.
YZS Indicates that the crack growth occurs from the start to the end of build in the YZ direction.
ZXM (or
Indicates that crack growth occurs at the middle plane in ZX direction.
ZX1/2)
In situations in which a test specimen is created from other locations with respect to the start of the
build (for example ¼, ¾, etc. distance from the start of the build) in the ZX direction, the notation
used should indicate this location. For example, ZX1/4 indicates that testing was conducted in the ZX
direction at a location one quarter of the way from the start of the build.
In situations where a test specimen (i.e. either a standard size or miniaturized specimen) is excised
from a portion of the build volume (e.g. from an actual part) this should be noted. The terminology
provided above should still be used to indicate the location of the excised sample with respect to the
original build volume.
