Rockwell Hardness - A Method-Dependent Standard Reference Material
Samuel R. Low III, R J. Gettings, Walter S. Liggett Jr, Jun-Feng Song
Rockwell hardness is not a fundamental physical property of a material. It is a method-dependent measurement of the deformation of the material to an applied force. There are no alternative measurement systems to directly or independently measure Rockwell hardness, nor are there intrinsic artifacts to base these standards on. Nevertheless, Rockwell hardness is an important measurement, widely used for process control and acceptance testing of metals and metal products. As a result, reference materials are essential for comparing Rockwell test results. This paper describes the challenges of developing a reference material for a method-dependent measurement.
