Results of Proficiency Test of the Hardness Calibration Laboratories Using the Reference Indentation for Brinell Hardness

Nae Hyung Tak, Hoon Sik Bae

Abstract

The indentation measurement of Brinell hardness is an important element that can determine the accuracy of measurement results. However, although the performance of hardness testers have significantly improved over the years, the deviation of indentation measurements among the testing centers has not changed. It is not even difficult to find testers who have differing measurement results for the same indentations. This paper is related to the proficiency test of calibration laboratories using the Brinell hardness reference indentation specified in ISO 6506-3.
