ASTM 18 – Standard Test Methods for Rockwell Hardness and Rockwell Superficial Hardness
ASTM E18 – Standard Test Methods for Rockwell Hardness and Rockwell Superficial Hardness
Hardness Standards?
For years, users of Rockwell Scale Hardness Testers have been attempting to achieve correlation between customer and vendor, machine to machine, and operator to operator. In many cases, this simple expectation has been an unrealistic goal. The major source of this dilemma has been the lack of a good, consistent hardness standard.
