Subcommittee F42 publishes new ISO/ASTM 52941 standard for AM

Stay up to date with everything that is happening in the wonderful world of AM via our LinkedIn community.

ASTM International committee F42 along with ISO TC261 has published the new ISO/ASTM 52941 standard that provides the additive manufacturing industry with qualification requirements and test methods for laser beam powder bed fusion (LB-PBF) in aerospace applications.

This standard improves the ability for AM components to be qualified for civil, commercial, and military aircraft, as well as space propulsion, payload, and manned space flight.

Developed under ASTM Subcommittee F42.07, Additive Manufacturing Technologies Applications, the ISO/ASTM 52941 standard covers Additive Manufacturing, System performance and reliability, and Acceptance tests for laser metal powder-bed fusion machines for metallic materials for aerospace applications.

ISO/ASTM 52941

The F42 subcommittee is a unique collaboration between leading standard organizations ASTM and ISO focused specifically on developing additive manufacturing standards. The enormous challenges of standardizing an entirely new and revolutionary production method required this first of its kind alliance between the competing organizations.

Currently active standards under the jurisdiction of F42.07 subcommittee are:

  • ISO/ASTM52942-20 Additive manufacturing — Qualification principles — Qualifying machine operators of laser metal powder bed fusion machines and equipment used in aerospace applications
  • ISO/ASTM52941-20 Additive manufacturing — System performance and reliability — Acceptance tests for laser metal powder-bed fusion machines for metallic materials for aerospace application

Proposed New Standards under the jurisdiction of F42.07 are:

  • WK66637 Additive Manufacturing — Finished Part Properties — Specification for 4340 Steel via Laser Beam Powder Bed Fusion for Transportation and Heavy Equipment Industries
  • WK67583 Additive Manufacturing — Feedstock Materials — Powder Reuse Schema in Powder Bed Fusion Processes for Medical Applications
  • WK73170 Additive manufacturing — Qualification principles — Qualifying machine operators of laser metal powder bed fusion machines and equipment used in aerospace applications
  • WK70164 Additive Manufacturing — Finished Part Properties — Standard Practice for Assigning Part Classifications for Metallic Materials
  • WK72659 Guideline for Material Process Validation for Additive Manufacturing of Medical Devices
  • WK71269 Additive manufacturing — Qualification principles — Quality requirements for industrial additive manufacturing sites
  • WK71375 Additive Manufacturing Qualification principles Part 1 :Qualification of Machine operators for metallic parts production
  • WK71376 Additive manufacturing — Qualification principles — Part 2: Qualification of machine operators for metallic parts production for PBF-LB
  • WK71377 Additive manufacturing — Qualification principles — Part 3: Qualification of machine operators for metallic parts production for PBF-EB
  • WK71378 Additive manufacturing — Qualification principles — Part 4: Qualification of machine operators for metallic parts production for DED-LB
  • WK71379 Additive manufacturing — Qualification principles — Part 5: Qualification of machine operators for metallic parts production for DED-Arc
  • WK73231 Additive manufacturing — System performance and reliability — Acceptance tests for laser metal powder-bed fusion machines for metallic materials for aerospace application
  • WK74302 Additive manufacturing for construction — process characteristics and performance — specification for manufactured polymeric UV cured structures for residential applications
  • WK73688 Additive manufacturing — Qualification principles — Generic machine evaluation and KPI Definition for LPBF-M Processes in Automotive Applications
