Scope

This part of GB/T 230 specifies the specifications of the Rockwell hardness tester (hereinafter referred to as the hardness tester) used for the determination of Rockwell hardness (A, B, C, D, E, F, G, H, K, N, T scales). Testing method. This part specifies the direct test method for testing the basic functions of the hardness tester and the indirect test method for the comprehensive test of the hardness tester. The indirect test method can be used independently for regular routine inspection of hardness testers in use. If the hardness tester can also be used for hardness testing by other methods, the hardness tester shall be tested separately according to each method. This section also applies to portable hardness testers, but the term "change of location" in the requirements of 6.1a) does not apply.
