There are two main testing methods for metal hardness testing. One is the static test method, in which the test force is applied slowly without impact. The determination of hardness mainly depends on the indentation depth, indentation projection area or indentation gravure area. Static test methods include Brinell hardness, Rockwell hardness, Vickers hardness, Knoop hardness, Webster hardness and Pasteur hardness. Brillouin, Perot and Vitrification are the most widely used testing methods, and they are the main testing methods for metal hardness testing. The Rockwell hardness test here is the most widely used and widely used in product inspection. According to statistics, 70% of the hardness testers currently used are Rockwell hardness testers. Another test method is dynamic test method, in which the application of test force is dynamic and influential. This includes Shore hardness and Richter hardness tests. Dynamic testing method is mainly used to test the hardness of large immovable workpiece.
