When testing coatings, scratch hardness refers to the force necessary to cut through the film to the substrate. The most common test is Mohs scale , which is used in mineralogy . One tool to make this measurement is the sclerometer .
Hardness testing NewSonic EN
Our hardness reference blocks include factory certificates (MPA certification also if requested) enabling ongoing verification and calibration of your UCI hardness testing devices to ensure consistently stable results. Reference blocks are available in different versions with certified hardness.
Rockwell Hardness Testing
Hardness is a characteristic of a material, not a fundamental physical property. It is defined as the resistance to indentation, and it is determined by measuring the permanent depth of the indentation...

What are the different hardness testing methods? ExtruDesign
Rockwell Hardness Testing. In the Rockwell test, we use the depth of the penetration to determine the hardness of the material rather than the surface area to determine the hardness. (In Brinell test we use the surface area of indent to determine the hardness). The remaining all actions are the same as the Brinell hardness testing.
