Additive manufacturing - Material extrusion-based additive manufacturing of plastic materials - Part 1: Feedstock materials (ISO/ASTM 52903-1:2020)

This document describes a method for defining requirements for plastic materials used in extrusion-based additive manufacturing (AM) processes. Materials include unfilled, filled, and reinforced plastic materials suitable for processing into parts. These materials can also contain special additives (e.g. flame retardants, stabilizers, etc.). Processes include all material extrusion-based AM processes.
This document is intended for use by manufacturers of materials, feedstocks, plastic parts or any combination of the three using material extrusion-based AM.
NOTE       In some cases, material manufacturers can also be feedstock manufacturers. In other cases, a material manufacturer can supply materials (example: pellets) to a feedstock manufacturer (example: converter of pellets into filaments).
This document does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Additive Fertigung - Materialextrusion-basierte additive Fertigung von Kunststoffen - Teil 1: Ausgangsmaterialien (ISO/ASTM 52903-1:2020)

Dieses Dokument beschreibt ein Verfahren zur Definition von Anforderungen an Kunststoffmaterialien, die in additiven Fertigungsprozessen (AM, en: additive manufacturing) auf Grundlage von Werkstoffextrusion verwendet werden. Materialien beinhalten nicht gefüllte, gefüllte und verstärkte Kunststoffmaterialien, die für die Verarbeitung zu Teilen geeignet sind. Diese Kunststoffe können auch spezielle Additive (z. B. Flammschutzmittel, Stabilisatoren usw.) enthalten. Die Prozesse umfassen alle AM-Prozesse auf Grundlage von Werkstoffextrusion.
Dieses Dokument ist zur Nutzung durch Hersteller von Werkstoffen, Ausgangsmaterialien, Kunststoffteilen oder jeglicher Kombination der drei unter Verwendung von AM auf Grundlage von Werkstoffextrusion vorgesehen.
ANMERKUNG   In manchen Fällen können Werkstoffhersteller auch Ausgangsmaterialhersteller sein. In anderen Fällen kann ein Werkstoffhersteller einem Ausgangsmateriallieferanten (Beispiel: Umformung von Granulat in Filamente) Werkstoffe (Beispiel: Granulat) bereitstellen.
In diesem Dokument werden nicht alle Sicherheitsrisiken, falls vorhanden, behandelt, die bei Anwendung der Norm auftreten können. Es liegt in der Verantwortung des Anwenders dieses Dokuments, geeignete Vorkehrungen für den Arbeits-, Gesundheits- und Umweltschutz zu treffen und vor der Anwendung festzulegen, welche einschränkenden Vorschriften gelten.

Fabrication additive - Fabrication additive de matériaux plastiques à base d'extrusion de matière - Partie 1: Matières premières (ISO/ASTM 52903-1:2020)

Le présent document décrit une méthode pour définir les exigences pour les matériaux plastiques utilisés dans les procédés de fabrication additive (FA) à base d'extrusion. Les matériaux comprennent des matériaux plastiques non filaires, filaires et renforcées adaptées à la transformation en pièces. Ces matériaux peuvent également contenir des additifs spéciaux (par exemple, retardateurs de flamme, stabilisants, etc.). Les procédés comprennent tous les procédés de FA à base d'extrusion de matière.
Le présent document est destiné à être utilisé par les fabricants de matériaux, matières premières, pièces en matière plastique ou toute combinaison des trois utilisant la FA à base d'extrusion de matière.
NOTE       Dans certains cas, les fabricants de matériaux peuvent également être des fabricants de matières premières. Dans d'autres cas, un fabricant de matériaux peut fournir des matériaux (exemple: pastilles) à un fabricant de matières premières (exemple: conversion de pastilles en filaments).
Le présent document ne prétend pas répondre à toutes les préoccupations en matière de sécurité, le cas échéant, associés à son utilisation. Il est de la responsabilité de l'utilisateur de la présente norme d'établir des pratiques appropriées de sécurité et de santé, et environnementales et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.

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
