kovuusarvona
Kovuusarvona is a term used in materials science to describe a specific type of hardness measurement, particularly prevalent in certain Scandinavian contexts. It translates directly to "hardness value" in English. This value is typically determined through standardized indentation tests, where a known load is applied to a surface using a specific indenter geometry. The resulting indentation size, or the depth of penetration, is then used to calculate the hardness number.
Different scales exist for hardness testing, such as Vickers, Brinell, and Rockwell, each with its own indenter
