Overview

EN ISO/ASTM 52941:2020 (adopted as EN ISO/ASTM 52941:2020 / SIST EN ISO/ASTM 52941:2021) specifies requirements and test methods for the qualification and re‑qualification of laser metal powder‑bed fusion (L‑PBF) machines used to produce metallic components for aerospace applications. It defines acceptance tests to verify system performance and reliability and can also be used for periodic inspections or after maintenance and repair.

Key topics and technical requirements

This standard focuses on machine‑level performance verification and includes test methods and criteria for:

Laser beam tests

Measurement of laser power and power stability (continuous‑wave and pulsed lasers)
Beam characteristics, minimum beam waist position and thermal stability
Laser beam position, trajectory accuracy and scanning speed
Requirements for multi‑laser systems

Mechanical function tests

Build platform positioning and feeding platform movement
Powder feed and powder spreading device performance, including spreader movement

Process environment and auxiliary systems

Build area heating system and control
Atmosphere control inside the working chamber (oxygen/inert gas management)
Gas flow testing (e.g., hot wire anemometry) as an optional test

Data, safety and documentation

Data recording provisions during tests
Verification of safety systems
Test reporting and re‑qualification procedures

Optional demonstrations

Use of demonstrator parts, build area assessment artifacts and trajectory patterns for additional verification

The standard references normative documents for laser measurement and AM terminology (e.g., ISO 11146, ISO 11554, ISO/ASTM 52900, 52921).

Practical applications

This standard is intended to:

Guide acceptance testing for newly installed L‑PBF machines destined for aerospace production

Support re‑qualification after major maintenance, repair, or upgrades

Provide a checklist for periodic inspections to maintain process control and traceability

Inform procurement and acceptance criteria when buying or commissioning machines

Who uses this standard

Aerospace manufacturers and suppliers using L‑PBF for metallic parts

Machine OEMs and system integrators conducting factory acceptance tests

Quality, qualification and maintenance engineers responsible for machine certification

Conformity assessment bodies and auditors validating machine readiness for aerospace use
