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.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical Barriers
to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 261, Additive manufacturing.
ISO 17296 consists of the following parts, under the general title Additive manufacturing — General

ISO 17296-3:2014(E)

Introduction
Additive manufacturing is a process of joining bulk raw materials to make parts from 3D model data,
usually layer upon layer, as opposed to subtractive manufacturing and formative methodologies. It is an
inherent part of the parts development or production process. It is used to manufacture prototypes and
production parts.
This part of ISO 17296 aims to offer recommendations and advice to machine manufacturers, feedstock
suppliers, machine users, part providers, and customers, to improve communication between these
stakeholders concerning test methods.
This International Standard has been developed within a set of consistent documents from terminology
to test methods and data exchange.
The manufacturing of parts by additive manufacturing processes is subject to numerous variables.
The processes described in ISO 17296-2 can be used to manufacture parts that meet technological
requirements only if these factors are controlled, optimized and, if necessary, customized for each order.
When assessing parts quality, comparison with the specific requirements is one of the most important
aspects.
Additive manufacturing processes require the selective application of thermo-physical and/or chemical
mechanisms to generate the part. Thus it is possible to produce parts with different characteristics,
depending on the method used and the process parameters. However, complete testing of all parts
characteristics is neither cost-effective nor technologically feasible. Therefore, when formulating parts
specifications, the nature and scope of testing is an important issue.

1 Scope
This part of ISO 17296 covers the principal requirements applied to testing of parts manufactured by
additive manufacturing processes.
This part of ISO 17296
— specifies main quality characteristics of parts,
— specifies appropriate test procedures, and
— recommends the scope and content of test and supply agreements.
This part of ISO 17296 is aimed at machine manufacturers, feedstock suppliers, machine users, part
providers, and customers to facilitate the communication on main quality characteristics. It applies
wherever additive manufacturing processes are used.

4 Main characteristics and corresponding test methods
4.1 General
Each development and fabrication phase of a part has a specific purpose. The performance criteria
determine the type of part and the choice of additive manufacturing process. This part of ISO 17296
develops the following main quality characteristics:
— feedstock:
— bulk raw material requirements: powder particle size, morphology, surface and distribution,
density (tap and apparent), flowability/pourability, ash content, and carbon content;
— parts:
— surface requirements: appearance, surface texture, and colour;
— geometric requirements: size, length and angle dimensions, dimensional tolerances, and
geometrical tolerancing (deviations in shape and position);
— mechanical requirements: hardness, tensile strength, impact strength, compressive strength,
flexural strength, fatigue strength, creep, ageing, frictional coefficient, shear resistance, and
crack extension;
— build material requirements: density and physical and physico-chemical properties
[microstructure analyses (non-destructive testing)].
NOTE The following other characteristics of parts have been identified but, due to the specificity of additive
manufacturing, will be provided in a future version of this part of ISO 17296:
— build material requirements: ductility;
— thermal properties (e.g. operating temperature range, dimensional stability in heat, softening temperatures,
melting point, specific heat, thermal conductivity, and coefficient of linear thermal expansion);
— electrical requirements (e.g. disruptive strength, dielectric properties, magnetic properties, and electrical
conductivity);
2) To be published.

ISO 17296-3:2014(E)

— physical and physico-chemical properties (e.g. internal defaults, flammability, toxicity, chemical composition,
chemical resistance, water absorption, crystalline structure, suitability for food, biocompatibility, sterility,
photostability, translucence, solidification point, glass transition, and corrosion).
4.2 Selection criteria
Testing categories given in Tables 1 to 3 shall be applied to guide the relation between customer and part
provider, applicable for metal parts, plastic parts, and ceramic parts. These testing categories define the
level of criticality of the parts:
— H: tests for highly engineered parts (safety critical);
— M: tests for functional parts that are not safety critical;
— L: tests for design or prototype parts.
For each testing category, the characteristics indicated (+) shall be fulfilled, the characteristics indicated
(o) are recommended, and the characteristics indicated (-) are not applicable. An agreement between
the customer and the part provider may exclude some of them due to specific applications of the part.
The choice of a testing category shall be subject to agreement between customer and part provider.
NOTE Test categories are defined according to the application and the type of material.
