WARNUNG — Dieses Dokument gibt nicht vor, alle unter Umständen mit der Anwendung des Verfahrens verbundenen Sicherheitsaspekte zu behandeln. 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.
Dieses Dokument umfasst den Betrieb und die Produktionskontrolle von PBF-Maschinen und -Prozessen (pulverbettbasiertes Schmelzen) für Bereiche mit kritischen Anwendungsanforderungen. Von einer kritischen Anwendung wird ausgegangen, wenn ein Funktionsausfall der Bauteile zu einer unmittelbaren Bedrohung führt.
Dieses Dokument gilt für die Fertigung von Bauteilen und mechanischen Probekörpern unter Verwendung des pulverbettbasierten Schmelzens (PBF) mit Laser- und Elektronenstrahlen.
Spezifikationen für bestimmte Anwendungsbereiche sind in den jeweiligen Normen angegeben.

Fabrication additive de métaux - Caractéristiques et performances du procédé - Procédé de fusion sur lit de poudre métallique en vue de répondre aux applications critiques (ISO/ASTM 52904:2024)

1.1 La présente pratique décrit le fonctionnement et le contrôle de production des machines et des procédés de fusion sur lit de poudre métallique (PBF) pour répondre à des applications critiques, telles que les composants aérospatiaux commerciaux et les implants médicaux. Les exigences contenues ci-après sont applicables aux composants de production et aux éprouvettes d'essai mécaniques utilisant la fusion sur lit de poudre (PBF) avec des faisceaux laser et électroniques.
1.2 La présente norme ne prétend pas traiter de tous les problèmes de sécurité, s'ils existent, associés à son utilisation. Il est de la responsabilité de l'utilisateur de la présente norme d'établir des pratiques de sécurité, d'hygiène et d'environnement appropriées, et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.
1.3 La présente Norme internationale a été élaborée conformément aux principes internationalement reconnus de normalisation établis dans la Décision sur les principes pour l'élaboration de normes internationales, guides et recommandations publiée par le Comité des obstacles techniques au commerce (OTC) de l'Organisation mondiale du commerce.
