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 document 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

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 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).

Introduction
Equipment manufacturers and service providers publish material properties for additively manufactured
components or specimens produced by powder bed fusion of metals using laser or electron beams.
Such published material properties are not always comparable, due to missing specifications on how
associated measurements were conducted. For example, the number of specimens tested, the number of
build jobs used, the specimen´s geometry and variations due to orientation are individually determined and
usually not published.
The objective of this document is to specify the minimum requirements for the determination and reporting
of material properties to support transparency and uniformity of material data sheets.

Additive manufacturing of metals — Powder bed fusion —
Presentation of material properties in material data sheets
1 Scope
This document specifies minimum content to be reported in material data sheets to justify the published
material property values. This document does neither aim to define compulsory test quantities nor to define
any basis for qualification purposes. Individual additions and extensions are permissible. This document is
intended for use by organisations throughout the additive manufacturing supply-chain, e.g., manufacturers
of PBF-LB/M or PBF-EB/M machines or comparable metal-powder-bed equipment, powder suppliers, service
providers and users of the additively manufactured components.

5 Material properties to be displayed
If a material is processed that is quantitatively specified according to its chemical composition and
mechanical properties for conventional manufacturing processes (e.g., for semi-finished products, bars,
profiles, bright products), at least those material properties shall be tested and reported (see Clause 7) that
are quantified in the respective standards for conventional means of manufacturing. An example for the
material grade 1.4404 according to EN 10088-3 is given in Annex A.
In cases where no standards are published that allow a definition of the scope of properties to be presented,
at least the following characteristic values shall be reported:
Chemical composition of the consolidated material
—  constituents mass in mass %
Mechanical properties
—  hardness e.g. in HV/HBW/HR/ HK
Vickers/Brinell/Rockwell/Knoop
—  yield strength R ; R in MPa
p e
—  tensile strength R in MPa
m
—  elongation at break A in %
Physical properties
—  relative density ρ in %
6 Optional material properties to be displayed
Optionally, properties can be shown in accordance with the material- and application requirements and the
applied test methods. Examples are (not an exhaustive list):
Mechanical properties:
— impact energy;

7 Boundary conditions for the determination of material properties
7.1 General
The manufacturing result of a PBF process depends on multiple influencing factors along the process chain.
Therefore, it is necessary to state the boundary conditions under which the reported properties were
derived. This includes
— the applied PBF machine(s) (see 7.2),
— the applied feedstock (see 7.3),
— the applied process parameters (see 7.4),
— the applied shielding gas (see 7.5),
— the applied powder spreading device (see 7.6), and
— the applied post-processing (see 7.7).
Thus, a material data sheet consists of two main parts:
a) The basic-information section, where the
