Additive manufacturing - Finished part properties - Orientation and location dependence of mechanical properties for metal powder bed fusion (ISO/ASTM DIS 52909:2021)
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.

3.1 Definition
3.1.1
Part location
location of the part/samplespecimen location within the build volume. 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 origin3.2 Abbreviations
The abbreviations used in this document and in particular in Figure A.1 are listed in Table 1.
Table 1 — AbbreviationsAbbreviation 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 specimenor part that provides a surface upon which the 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)

Abbreviation Signification Comment
B Both crack growth captures both start and end of build. (see Annex A)
RD Raster direction this may or may not be the same throughout the build. (see Annex A)
3.3 AcronymsThe acronyms used in this document are listed in Table 2. They are illustrated in Figure A.4.
Table 2 — AcronymsAcronym Signification
XY, YX, XZ, ZX, the first letter represents the direction normal to the crack plane and the second letter represents
YZ, ZY the expected direction of crack extensionXYB 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 ZX1/2) indicates that crack growth occurs at the middle plane in ZX direction
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.4 Summary of guide
4.1 The purpose of this document is to provide guidelines for test methods referenced in Clause 2
and also use some of the terminologies defined in ISO/ASTM 52900 for use with metal additive
manufacturing test specimens. Test specimens may be built directly to net-shape, or near net-shape, or
excised from a part.4.2 Standard geometries can be used based on the reference standards indicated in Clause 2, however,
direct testing of a part is a highly recommended practice for metal AM (See Annex A.6).
4.3 In order to investigate and document orientation and location-specific mechanical properties,
cut small-scale specimen from the relevant locations of the parts should be achieved . This document
describes some principles to applyfor the testing of various properties.5 Significance and use
5.1 Although evaluation of mechanical properties of many additively manufactured materials can be
conducted using the guidelines developed for conventional materials within existing testing standards,
the coordinate systems and nomenclature specific to conventional materials testing (for example in
ASTM E399, ISO 12135 and ASTM E647) are not sufficient to be applicable across the full spectrum
