Additive manufacturing - Round robin testing - General guidelines (ISO/ASTM TR 52917:2022)
This document is focused on the management of the round robin study (RRS) and can provide guidance for the scope development, planning, and execution of the RRS study. It can provide guidance to identify the feedstock, machine operations, process controls, and post-processing operations prior to running the study. RR organizers can identify controlled and free parameters in the study. This document can also provide guidance on the selection and use of test methods that can be applicable. The RRS investigates the variations found in AM parts. The outcome of the study can be used to improve the maturation of AM technologies.
A RRS, as described in this document, is different from an inter-laboratory comparison because an inter-laboratory study establishes the variability in a measurement method when undertaken by multiple users on a well-controlled artefact.
Additive Fertigung - Ringversuche - Allgemeine Leitlinien (ISO/ASTM TR 52917:2022)
Dieses Dokument fokussiert sich auf das Management der Ringstudie (RRS) und kann als Anleitung für die Entwicklung des Anwendungsbereichs, die Planung und die Ausführung der RRS-Studie dienen. Es kann als Anleitung für die Identifizierung des Ausgangsmaterials, des Maschinenbetriebs, der Prozesssteuerungen und der Nachbearbeitungsaktivitäten vor dem Beginn der Studie dienen. RRS-Organisatoren können kontrollierte und freie Parameter in der Studie identifizieren. Dieses Dokument kann außerdem als Anleitung für die Auswahl und Nutzung anwendbarer Prüfverfahren dienen. Die RRS untersucht die in AM-Teilen erkannten Abweichungen. Das Ergebnis der Studie kann verwendet werden, um die Reife von AM-Technologien zu verbessern.
Eine wie in diesem Dokument beschriebene RRS unterscheidet sich von dem laborübergreifenden Vergleich, weil diese die Variabilität in einem Messverfahren bei Anwendung durch mehrere Anwender an sorgfältig kontrollierten Artefakten bestimmt.
Fabrication additive - Essais interlaboratoires - Lignes directrices générales (ISO/ASTM TR 52917:2022)
Le présent document est axé sur la gestion de l’étude interlaboratoires (EIL) et peut fournir un guide pour le développement du domaine d’application, la planification et l’exécution de l’étude EIL. Il peut fournir un guide pour identifier la matière première, les opérations de la machine, les contrôles de procédé et les opérations de post-traitement avant d’exécuter l’étude. Les organisateurs d’EIL peuvent identifier des paramètres contrôlés et libres dans l’étude. Le présent document peut également fournir un guide sur la sélection et l’utilisation des méthodes d’essai qui peuvent être applicables. L’EIL examine les variations observées dans les pièces de FA. Le résultat de l’étude peut être utilisé pour améliorer la maturation des technologies de FA.
Une EIL, telle que décrite dans le présent document, est différente d’une comparaison interlaboratoires parce qu’une étude interlaboratoires établit la variabilité d’une méthode de mesure lorsqu’elle est mise en œuvre par de multiples utilisateurs sur un artefact bien contrôlé.

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.

ISO/ASTM TR 52917:2022(E)
Introduction
This document outlines the steps with regard to aspects of design to conduct and run a round robin
study (RRS) to assess the degree of variability in an additive manufacturing material or process.
The RRS can be used to study variations arising from the AM production process including feedstock,
machine operation, process control, and post processing. The RRS plan can identify various aspects of
the AM process to be considered to execute the study so that it is possible to maximize the consistency
of the results based on the objective of the study.
Additive manufacturing is still a developing technology and round robin studies play an important role
to help generate the information needed to populate materials engineering databases, determine design
allowables, and improve processing and post-processing consistency in order to drive maturation.
The result of the RRS is a qualitative or quantitative assessment of the material used or the process
variability, rather than the assessment of accuracy and precision of a specific test method from an inter-
laboratory study. Additionally, RRS can involve other entities besides laboratories.
Round robin studies differ from normal research studies by having different participants, each trying
to undertake a nominally identical process. The aim is to determine the effect of the desired variables
on the process outcome. The output can be used for different applications such as the demonstration
of process robustness or for derivation of material property data. A well-conducted RSS does not
guarantee small variability, but ensures that any observed variability is indicative of the material or
process, not poor study design.
