Overview
EN ISO/ASTM 52927:2024 - published jointly by ISO/ASTM and adopted by CEN - defines the principal requirements and test methods for parts produced by additive manufacturing (AM). The standard identifies main quality characteristics for both feedstock and finished parts, specifies procedures to build test specimens using AM processes, and recommends the scope and content of test and supply agreements to improve communication across the AM supply chain. It supersedes EN ISO 17296‑3:2016 and consolidates content from previous ISO and ASTM documents.

- Chemical characteristics (composition, ash/carbon content)
- Quality characteristics for parts
- Surface requirements (appearance, colour)
- Geometric and dimensional requirements (profile, roughness, orientation, tolerancing)
- Mechanical requirements (hardness, tensile, compressive, flexural, fatigue, creep, shear, friction)
- Test specimen production
- Specific procedures for building specimens using AM processes to ensure representative test results
- Process monitoring and testing scope
- Recommendations for process monitoring, feedstock testing, and part testing aligned to intended part performance
- Agreement guidance
- Recommended content and scope for test and supply agreements between vendors, machine manufacturers, and customers
- Material-specific annexes

- Annex B: polymer materials
- Annex C: ceramic materials
Applications
This standard is practical for:
- Developing AM qualification programs and test plans
- Defining acceptance criteria in supplier contracts and purchase specifications
- Designing representative specimens and comparative tests for AM-produced parts
- Establishing consistent feedstock inspection and lot-release procedures
- Guiding R&D when comparing AM process parameters and machine platforms

Who should use this standard
- Machine manufacturers - to specify build and monitoring requirements
- Feedstock suppliers - to define powder/filament quality and tests
- AM system users and part providers - to qualify parts and processes
- Customers and procurement teams - to include clear test/supply agreement terms

Future revisions intend to expand coverage to thermal, electrical and physico‑chemical properties as AM knowledge advances.
