An Empirical Approach to Determining Rockwell Hardness Measurement Uncertainty

Abstract
Characteristics of the empirically developed Rockwell hardness test make it difficult to determine measurement uncertainty using methods traditionally applied to other metrological measurements. An empirical approach to determining Rockwell hardness uncertainty has been developed, which provided a method based on the familiar procedures and practices of Rockwell hardness testing laboratories. The approach views the hardness machine and indenter as a single measuring device, and considers uncertainties associated with the overall measurement performance of the Rockwell hardness machine with respect to reference standards. The approach also considers the uncertainty contributions associated with the machine repeatability and the usage of the machine over time with varying environmental conditions and with different operators.Proceedings Title
