Additive manufacturing for aerospace - General principles - Part classifications for additive manufactured parts used in aviation (ISO/ASTM 52967:2024)
1.1 This document is intended to be used to assign part classifications across the aviation industries that use AM to produce parts.
1.2 This document is applicable to all AM technologies defined in ISO/ASTM 52900 used in aviation.
1.3 This document is intended to be used to establish a metric for AM parts in downstream documents.
1.4 This document is not intended to establish criteria for any downstream processes, but rather to establish a metric that these processes can use.
1.5 The part classification metric could be utilized by the engineering, procurement, non-destructive inspection, testing, qualification, or certification processes used for AM aviation parts.
1.6 The classification scheme in this document establishes a consistent methodology to define and communicate the consequence of failure associated with AM aviation parts.
1.7 This document is not intended to supersede the requirements and definitions of the applicable regulations or policies, including but not limited to the ones listed in Annex A1.
1.8 Tables A.1.1-A.1.3 align the existing regulations and guidance with the four part classes established herein. However, this alignment should not be construed as an alignment of the existing regulations to each other.
1.9 The material or process, or both, in general does not affect the consequence of failure of a part, therefore the classification scheme defined in this document may be used outside AM.
1.10 The user of this document should not assume regulators’ endorsement of this document as accepted mean of compliance.
1.11 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 document to establish appropriate safety, health, and environmental documents and determine the applicability of regulatory limitations prior to use.
1.12 This document was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Fabrication additive pour l'aérospatiale - Principes généraux - Classification de pièces pour les pièces produites par fabrication additive utilisées dans l'aviation (ISO/ASTM 52967:2024)
1.1 Le présent document se destine à être utilisée pour attribuer des classifications de pièces dans les industries de l'aviation qui utilisent la fabrication additive pour produire des pièces.
1.2 Le présent document s'applique à toutes les technologies de FA définies dans la norme ISO/ASTM 52900 utilisées dans l'aviation.
1.3 Le présent document se destine à être utilisée pour établir une mesure pour les pièces FA dans les documents en aval.
1.4 Le présent document ne se destine pas à établir des critères pour les processus en aval, mais plutôt à établir une mesure qui puisse être utilisée dans ces processus.
1.5 La mesure de classification des pièces pourrait être utilisée par les processus d'ingénierie, d'approvisionnement, d'inspection non destructive, d'essai, de qualification ou de certification utilisés pour les pièces d'aviation FA.
1.6 Le système de classification du présent document établit une méthodologie cohérente pour définir et communiquer les conséquences d'une défaillance associée aux pièces d'aviation FA.
1.7 Le présent document ne se destine pas à remplacer les exigences et les définitions des réglementations ou politiques applicables, y compris, mais sans s'y limiter, celles énumérées à l'Annexe A.1.
Tables A.1.1-A.1.3 alignent la réglementation et les directives existantes avec les quatre classes de pièces établies dans le présent document. Cependant, il convient que cet alignement ne soit pas interprété comme un alignement des réglementations existantes les unes par rapport aux autres.
1.8 Le matériau ou le procédé, ou les deux, n'a généralement pas d'effet sur la conséquence d'une défaillance d'une pièce; le système de classification défini dans le présent document peut donc être utilisé en dehors de la FA.
1.9 Il est recommandé à l'utilisateur du présent document de ne pas supposer que les autorités réglementaires approuvent le présent document, en tant que moyen de conformité accepté.
1.10 Le présent document ne prétend pas répondre à toutes les préoccupations en matière de sécurité, le cas échéant, associées à son utilisation. Il incombe à l'utilisateur du présent document d'établir des pratiques appropriées en matière de sécurité, de santé et d'environnement et de déterminer l'applicabilité des restrictions réglementaires avant utilisation.
1.11 Le present document a été élaboré conformément aux principes de normalisation internationalement reconnus établis dans la Décision sur les principes d'élaboration de normes, guides et recommandations internationaux publiée par le Comité des obstacles techniques au commerce (OTC) de l'Organisation mondiale du commerce (OMC).

Introduction
The use of additive manufacturing (AM) technology allows designs that may not be achieved with
traditional manufacturing methods. It is important to understand the risk associated with the AM usage
by understanding the consequence of failure (including the loss of intended function) of the usage. Such
information can be beneficial in establishing consistent manufacturing, inspection, or qualification processes
relative to a defined risk scale, which can serve as supporting data when seeking regulatory approval of an
AM part. A part classification scheme based on a part’s consequence of failure can provide a consistent risk
metric. Without carefully defined part classes, the ability to accurately gauge the consequence of failure
associated with additively manufactured aviation parts within and across programs, projects, and suppliers
becomes exceedingly difficult, resulting in mitigations that are either not commensurate or inconsistent.
The part classification scheme documented here does not affect a part’s functional requirements, but rather
is used to group additive manufacturing aviation parts into categories which can be used in downstream
standards. For example, this classification scheme can be used in material and process specifications to
determine the appropriate levels of process control, thermal post processing, qualification, and inspection
to ensure AM parts meet their application requirements. This classification scheme does not specify how the
classification is used in any downstream processes. The use of the classification shall be left to the cognizant
engineering or production entities, or downstream documents which reference this standard.

1.2 This practice is applicable to all AM technologies defined in ISO/ASTM 52900 used in aviation.
1.3 This practice is intended to be used to establish a metric for AM parts in downstream documents.
1.4 This practice is not intended to establish criteria for any downstream processes, but rather to establish
a metric that these processes can use.
1.5 The part classification metric could be utilized by the engineering, procurement, non-destructive
inspection, testing, qualification, or certification processes used for AM aviation parts.
1.6 The classification scheme in this practice establishes a consistent methodology to define and
communicate the consequence of failure associated with AM aviation parts.
1.7 This practice is not intended to supersede the requirements and definitions of the applicable
regulations or policies, including but not limited to the ones listed in Annex A1.
Tables A.1.1-A.1.3 align the existing regulations and guidance with the four part classes established herein.
However, this alignment should not be construed as an alignment of the existing regulations to each other.
1.9 The material or process, or both, in general does not affect the consequence of failure of a part,
therefore the classification scheme defined in this document may be used outside AM.
1.10 The user of this standard should not assume regulators’ endorsement of this standard as accepted
mean of compliance.
1.11 This standard 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, health, and environmental practices
and determine the applicability of regulatory limitations prior to use.
1.12 This international standard was developed in accordance with internationally recognized principles on
standardization established in the Decision on Principles for the Development of International Standards, Guides
and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
