Abstract
Rockwell hardness is a method-dependent measurement of the deformation of a material in response to an applied force. It is not a fundamental physical property of a material. There are no alternative measurement systems to directly or independently measure Rockwell hardness, nor are there intrinsic artifacts on which to base Standard Reference Materials. Nevertheless, Rockwell hardness is an important measurement, widely used for process control and acceptance testing of metallic materials and 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.
