Application Summary AI generated
This standard specifies the method for testing the surface hardness of pattern materials used in investment casting, such as waxes and plastics. It is applied in foundries and quality control laboratories to evaluate the resistance of pattern surfaces to indentation or deformation during handling and storage. The test ensures pattern integrity, which directly impacts the dimensional accuracy and surface finish of the final cast metal parts.
