This standard is the first part of a series, specifying the principles of Rockwell hardness (Scale A) testing for hard metals, requirements for testing equipment, specimen specifications, the specific procedures for testing, and how to express and report the results. This method is specifically used for determining the Rockwell hardness (Scale A) of hard metals. The core instrument for performing this test is the Rockwell hardness tester, which uses a diamond cone indenter to apply the test force in two steps (typically 588 N/60 kgf), and then obtains the hardness value by measuring the residual depth of the indentation. This method is particularly suitable for hard metal materials such as tungsten carbide.
