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).

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.

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).

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.

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.
