Batec Hardness Testing Issues
Balls that are fiveeighths of an inch diameter (16mm) and larger are surface ground flat and parallel. For hardness testing very large and therefore very expensive balls an alternative hardness test method must be used. This alternative method is used for hardness testing balls made of exotic materials that may cost hundreds of dollars a piece.
