GB/T 5766-2023 "Test Method for Rockwell Hardness of Friction Materials" specifies the test method for Rockwell hardness of friction materials (such as brake pads). Using a Rockwell hardness tester (primarily the H scale), the indentation depth of a diamond cone indenter under a specific load is measured and converted into a hardness value to evaluate the material's compressive resistance and wear resistance.
