The draft ISO/ASTM CD 52927 “Additive manufacturing — General principles — Main characteristics and corresponding test methods” has changed from status CD (“Committee Draft” – draft for enquiry, subject to members input) to DIS (“Draft International Standard” – draft for enquiry, subject to public input). This draft specifies the main requirement for testing and characterising of metallic, ceramic or polymer parts manufactured by additive manufacturing.
The document provides:
- A list of quality characteristics of parts and the corresponding test procedures.
- Recommendations on the scope and content of test and part supply agreements.
- Information on monitoring the process.
- Annexes on test methods for metallic, polymer and ceramic materials including the following:
- Definition of criticality of part
- Surface requirements
- Geometric requirements
- Mechanical requirements;
- Hardness
- Tensile strength
- Impact strength
- Compressive strength
- Fatigue strength
- Crack extension
- Physical and chemical property requirements
- Performance criteria and quality characteristics
In addition, the document contains a comprehensive list of standards for various (mechanical) testing and characterisation methods.
