Overview
ISO/ASTM TS 52930:2021 provides qualification principles for additive manufacturing (AM) equipment used in PBF-LB (powder bed fusion - laser beam) processes. The technical specification focuses on machine-related aspects of installation qualification (IQ), operational qualification (OQ) and performance qualification (PQ) that directly influence material consolidation and the ability to produce repeatable, conforming metal parts. It is machine-centric, intended for organizations with established quality systems, and explicitly excludes feedstock qualification and post-processing beyond powder removal. Process mapping, risk assessment and validation planning are identified as necessary pre-conditions but are outside the document’s scope.
Key Topics
- Definitions & scope: IQ, OQ, PQ, FAT, SAT, SPC and other AM-specific terms referenced to ISO/ASTM 52900.
- Installation Qualification (IQ): Objective evidence that equipment and ancillary systems are installed per manufacturer specifications and supplier recommendations.
- Operational Qualification (OQ): Establishes process control limits and action levels to ensure product meets predetermined requirements.
- Performance Qualification (PQ): Demonstrates that the process consistently produces conforming parts under anticipated production conditions.
- Supportive activities: Calibration, verification, system acceptance tests (FAT/SAT), documentation and change control.
- Statistical process control (SPC): Process capability evaluation included (Annex A) for monitoring process stability and variability.
- Revalidation: Criteria for when revalidation is necessary (e.g., equipment changes or process drift).
Applications
This standard is practical for:
- AM manufacturers and OEMs using metal PBF-LB for serial production
- Quality, validation and process engineers implementing machine qualification programs
- Procurement teams conducting FAT/SAT and acceptance testing of PBF-LB equipment
- Regulated industries (aerospace, medical, automotive) that require documented IQ/OQ/PQ and demonstrated process control
Benefits include providing a structured framework to qualify AM machines, reduce reliance on destructive end-product testing, support statistical monitoring (SPC), and help ensure consistent part quality in production environments.
