Evolution of standardisation project on AM - general principles, main characteristics and corresponding test methods

Article
Guido Heunen
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.
