GB/T 4340.1-2024 Metallic Materials, Vickers Hardness Test, Part 1: Test Methods is a Chinese national standard that specifies in detail the principle, hardness gauge, specimen, test procedure, result uncertainty and test report of the Vickers Hardness Test for metals. It is suitable for the determination of Vickers Hardness of metal materials under different test force ranges, including the requirements of the indentation measurement device of the Vickers hardness tester, the preparation and requirements of the sample, the selection and application of the test force, and the Measuring method of the diagonal length of the indentation. The implementation of the standard will improve the accuracy and conformity of the metal hardness of materials test.
