Overview
EN ISO/ASTM 52926-3:2023 - Additive manufacturing of metals - Qualification principles - Part 3: Qualification of operators for PBF‑EB (ISO/ASTM 52926-3:2023) is a CEN‑adopted international standard that defines the capabilities, responsibilities and assessment criteria for operators of powder bed fusion - electron beam for metals (PBF‑EB/M) systems. It provides guidance for both theoretical and practical qualification of personnel who set up, run and support PBF‑EB metal additive manufacturing in general industrial applications.
Key topics and requirements
- Scope and intent: Guidance for qualification of AM machine operators in metallic part production using PBF‑EB/M; intended for general industrial use and regulated sectors.
- Training expectation: Candidates should receive theoretical and practical training (example cited: 24 hours) or possess equivalent experience before assessment.
- Assessment structure:
- Theoretical test: Minimum of 20 multiple‑choice questions (four options, one correct); minimum passing score 60%.
- Practical test: Demonstration of hands‑on skills to perform all process steps according to a documented manufacturing plan.
- Technical topic areas evaluated (aligned with clauses 4.2.2–4.2.7):
- PBF‑EB/M system knowledge: system components, functions, process advantages and limitations.
- Feedstock activities: powder handling, characteristics and consumables.
- System set‑up: build platform, chamber and beam-related setup.
- Manufacturing/build activities: process parameters and their effects on as‑built parts.
- Post‑processing: finishing, heat treatment and handling after build.
- Quality‑related activities: inspection, traceability and process control.
- Documentation: Qualification tests should follow documented procedures or manufacturing plans.
Practical applications
- Ensures consistent, safe and reproducible PBF‑EB production of metal parts.
- Useful for:
- Manufacturers adopting or scaling PBF‑EB/M production lines.
- Quality managers and production engineers developing operator competency programs.
- Training providers designing syllabus and assessments for PBF‑EB operator courses.
- Regulated industries (aerospace, automotive, medical, railway, industrial plants) where operator competence affects part conformity and safety.
Who should use this standard
- AM machine operators, shift leads and supervisors
- HR and competency assessors
- Certification bodies and training organizations
- Design and process engineers implementing PBF‑EB workflows
