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.

Introduction
This document covers the definition and communication of requirements for purchased parts made by
additive manufacturing. It is intended to enable efficient and unambiguous communication between the
part providers and the customers of parts made by additive manufacturing to ensure that the resulting
part meets the customer’s requirements. It is intended that the document is used by the part providers
and/or the customers of parts made by additive manufacturing.
This document is a top-level standard in the hierarchy of additive manufacturing standards in that it
is intended to apply to parts made by any additive manufacturing process and any material type. The
document allows for different requirements based on the classification of the criticality and expected
end use of the parts made by additive manufacturing.

1 Scope
This document defines and specifies requirements for purchased parts made by additive manufacturing.
It gives guidelines for the elements to be exchanged between the customer and the part provider
at the time of the order, including the customer order information, part definition data, feedstock
requirements, final part characteristics and properties, inspection requirements and part acceptance
methods.
It is applicable for use as a basis to obtain parts made by additive manufacturing that meet minimum
acceptance requirements. More stringent part requirements can be specified through the addition of
one or more supplementary requirements at the time of the order.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

3.1
pre-shipment inspection
inspection carried out by the part producer on the parts to be supplied according to the part definition
or on the test units in order to verify that these parts are in compliance with the order requirements
3.2
qualification part
part fabricated prior to commencing production which is used to qualify specific aspects of the
manufacturing process or part characteristics in order to use as a basis to initiate production

3.3
first production part
part with the same geometry (and with the same tolerances), same material and same properties as the
one requested by the order that allows verification by the customer (3.8) that the production processes
are capable of producing parts that meet the requirements
3.4
reference part
part with characteristics similar to the desired final parts but with different geometry or scale or
features that can be easily measured or characterized
Note 1 to entry: Reference parts are typically sacrificial parts with simple geometries that are used to verify
build properties and reduce measurement effort.
3.5
acceptance
agreement between the customer (3.8) and the part provider (3.7) that the delivered part(s) meet the
purchase order requirements
3.6
inspection plan
set of instructions specifying the process of verification including appropriate resources and sequence
of inspections to be referenced by the manufacturing plan

This document is a top-level standard in the hierarchy of additive manufacturing standards in that it
is intended to apply to parts made by any additive manufacturing process and any material type. The
document allows for different requirements based on the classification of the criticality and expected
end use of the parts made by additive manufacturing.

Additive manufacturing — General principles —
Requirements for purchased AM parts
1 Scope
This document defines and specifies requirements for purchased parts made by additive manufacturing.
It gives guidelines for the elements to be exchanged between the customer and the part provider
at the time of the order, including the customer order information, part definition data, feedstock
requirements, final part characteristics and properties, inspection requirements and part acceptance
methods.
It is applicable for use as a basis to obtain parts made by additive manufacturing that meet minimum
acceptance requirements. More stringent part requirements can be specified through the addition of
one or more supplementary requirements at the time of the order.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their content
constitutes requirements of this document. For dated references, only the edition cited applies. For
undated references, the latest edition of the referenced document (including any amendments) applies.

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

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.

Introduction
This document covers the definition and communication of requirements for purchased parts made by
additive manufacturing. It is intended to enable efficient and unambiguous communication between the
part providers and the customers of parts made by additive manufacturing to ensure that the resulting
part meets the customer’s requirements. It is intended that the document is used by the part providers
and/or the customers of parts made by additive manufacturing.
This document is a top-level standard in the hierarchy of additive manufacturing standards in that it
is intended to apply to parts made by any additive manufacturing process and any material type. The
document allows for different requirements based on the classification of the criticality and expected
end use of the parts made by additive manufacturing.
