Features: The accuracy and comparability of metal hardness test results are affected by many factors, mainly including the surface quality and shape and dimensions of the specimen, the accuracy and stability of the hardness tester, and particularly the selection of test conditions and operational techniques and experience of the test personnel, which greatly influence the correctness of the test results. In addition, selecting appropriate methods for testing based on the type, characteristics, and applications of metallurgical products is also very important for correctly evaluating the hardness properties of materials. These test method standards are specifically formulated for the characteristics of various hardness tests, thereby restricting the aforementioned influencing factors.
