Samuel Low, Alessandro Germak, Konrad Herrmann

Abstract

The measurement of hardness is used extensively by many of the world's manufacturing industries. The conventional hardness tests are the most commonly used methods for acceptance testing and production quality-control of metals and metallic products. For these industries to be successful, it is important that measurements made by suppliers and customers agree within some practical limits. Measurement traceability is a key factor in assuring hardness measurement agreement. This paper discusses the traceability issues related to the measurement of conventional hardness, including calibration, verification and uncertainty.
