GB/T 21838.1-2019 provides a detailed test method for the instrumented indentation test of metal hardness of materials and material parameters. The standard describes the principle and puts forward requirements for the accuracy and indenter characteristics of the instrument and equipment. Clarify the preparation specifications of the sample, including size, surface state, etc. Describe the test process in detail, covering indentation force control, displacement measurement, data collection and processing. According to this standard, the relevant characteristics of metal materials can be accurately obtained, providing strong data support for material research and development and mass testing, and promoting the research and application of metal material performance.
