However, we haven’t talked as much about comparing the scales and what makes them different. Here we want to go more into comparing the hardness scales themselves. First though, a quick word about testing methodology. These different scales are measured by using different hardness testing equipment and methodology, but Vickers, Rockwell and Brinell and even Shores have one thing in common, they are all measuring the hardness by indentation. Whether it’s the carbide ball of a Brinell Test or the... Continue reading
