GB/T 9097-2016 specifies the determination method of apparent hardness and microhardness of sintered metal materials (excluding cemented carbide). The standard describes the test principle and puts forward requirements for the accuracy of the required equipment. Detail the specific steps of sample preparation, standardize the test process of apparent hardness and microhardness, including the selection of test force, loading method, Measuring location determination, etc. Through this standard, the relevant Hardness can be accurately measured, providing a basis for performance evaluation and quality control of sintered metal materials, and is widely used in material research and development, production and testing.
