ISO 6506 / 6507 / 6508
Hardness Testing of Metallic Materials
Hardness testing quantifies a material’s resistance to permanent surface deformation. Three principal methods cover the range from soft alloys to hardened steels: Brinell (ISO 6506), Vickers (ISO 6507), and Rockwell (ISO 6508). Results guide heat-treatment verification, incoming material inspection, and quality control throughout metalworking supply chains.
What it measures
- Brinell Hardness Number (HBW)
- Vickers Hardness (HV)
- Rockwell Hardness (HRC / HRB / HRA)
- Knoop Hardness (HK) -- microindentation
