SIST EN ISO/ASTM 52920:2023 PDF

Overview

EN ISO/ASTM 52920:2023 (ISO/ASTM 52920:2023) defines qualification principles and requirements for industrial additive manufacturing (AM) processes and production sites. It is aimed at part manufacturers and is independent of material and specific AM technology (applies to technologies defined in ISO/ASTM 52900). The standard specifies criteria for AM-relevant processes, quality‑relevant characteristics across additive system operations, and sequences and activities within an AM production site. It complements, rather than replaces, an organization's quality management system.

Key topics and technical requirements

The standard addresses practical, process-focused topics for AM qualification and quality assurance, including:

• Infrastructure and site requirements
  • AM system installation, ancillary equipment, feedstock storage, IT infrastructure, foreign object debris (FOD) controls, and provision of process resources.
• Manufacturability assessment and review
  • Design and manufacturing reviews, process finalization and post‑processing considerations.
• Qualification of additive system operations
  • Scope of qualification, validation planning, process mapping, risk assessment, and creating a master validation plan.
• IQ/OQ/PQ approach
  • Installation Qualification (IQ), Operational Qualification (OQ) and Performance Qualification (PQ) for AM systems and the complete process chain.
• Manufacturing plan and documentation
  • Manufacturing plan specification, documentation and traceability of process steps, and required IQ/OQ/PQ documentation.
• Process-specific requirements
  • Data preparation, feedstock management, system set‑up, build cycle operations, and process finalization.
• Quality assurance and controls
  • Personnel competence, handling non‑conformities, continuous improvement, production run approval and part approval. Annexes cover post‑processing and supplementary guidance.

Note: Environment, health and safety (EHS) is not covered comprehensively and is addressed in equipment manufacturer guidance and other AM standards.

Applications and who should use it

This standard is intended for:

• AM part manufacturers and production site managers establishing or scaling industrial AM operations
• Process engineers and validation engineers implementing IQ/OQ/PQ for AM
• Quality managers integrating AM‑specific requirements into QMS
• Suppliers and OEMs qualifying AM processes for series production
• Auditors and certification bodies assessing AM production readiness

Use cases include qualifying new AM equipment, validating production processes for serial manufacturing, establishing traceability and control of feedstock, and documenting manufacturing plans and approvals.
