GB/T 21838.1-2008 specifies the instrumented indentation test method for the hardness of materials and material parameters of metals. In the performance testing of metal materials, the test can accurately obtain key data. The standard specifies the applicable range of metal materials, elaborates the test principle in detail, and introduces the composition and technical requirements of instrumented indentation equipment. Standardize the preparation process of samples, and make strict regulations on the test process, such as loading and unloading methods, indentation depth control, data collection Frequency, etc. Also give the calculation method of Hardness and material parameters. Provide a unified and scientific operation specification for instrumented indentation testing of metal materials, and help improve the accuracy and Reliability of testing.
