Technical standards
Tupy shots and grits are classified according to their shapes and sizes and according to standards SAE J444 and SAE J445, which specify the mechanical tests and SAE J827 which establishes limits for shape deviation, chemical composition, microstructure, hardness and non-magnetic contaminants.
